Where is the crank sensor located on a car?

Where is the crank sensor located on a car?

The crank sensor is one of the most important sensors in a car, if not the most important. Without the crank sensor or if the sensor itself is faulty, a car might not start or it might have issues while running, like cutting out. This sensor is the one that is going to feed the electronic control unit with a signal that measures the engine's revolutions per minute. Without the crank sensor feeding the RPM signal, the electronic control unit is not able to control the ignition system timing properly.
Common issues regarding a faulty crank sensor are misfiring, backfire, engine experiencing an irregular idle, the acceleration behavior becomes irregular, the engine won't start after heating up but has no problems starting once it cools down again. Most common causes of a crank position sensor failure are by exposure to extreme heat. This problem has been solved with more recent car models because the latest crank sensors are now closed units, which prevents damage from extreme heat, water or other fluids.

The crank sensor is either located on the main crank pulley, the flywheel, the camshaft or on the crankshaft itself. The most common location is at the bottom of the engine block,

How do you locate the camshaft sensor in a car?

Typically, the camshaft sensor is located at the top of the engine to the front and mounted near the crankshaft in front of a wheel. The wheel has windows or slots that allow the sensor to count each revolution of the camshaft. The sensor is readily accessible if it needs to be changed. However, some imported cars, including Hondas, have the crankshaft and camshaft sensors inside of the distributor, requiring replacement of the entire distributor for this type of vehicle. 

Signs of a failing camshaft sensor may include the engine misfiring or hesitating while accelerating, a check engine light, and problems starting or immediately dying after starting. A standard set of socket wrenches or set of box wrenches is the only tool needed to change a faulty sensor. If you have a multimeter, you can remove and test the sensor. Connect it to the meter, set the meter to detect resistance and rapidly pass a magnet in front of its eye. You should see significant jumps in the reading on the meter as the magnet passes if the sensor is good.
To replace the camshaft sensor, remove it by depressing the side tabs on the electrical connector wired to the camshaft sensor and unplug it. Remove the retaining bolt holding the sensor in place and gently twist the sensor back and forth as you pull it free. Insert the new sensor, and twist it into place in a similar manner. Tighten the retaining bolt, and plug the connector in to complete the replacement.

What are some common problems with crankshaft position sensors?

Common problems with crankshaft position sensors include connector pins that are loose, cracks in the sensors and improper gaps between the reluctor wheel and the sensor tip. Faulty sensors can prevent a car from starting and cause engine stalling. Failed crankshaft position sensors can activate the check engine light. 

When crankshaft position sensors are failing, they cause sporadic stalling or long cranking in damp weather, or in hot engines. Hot cars that stall but start again once their engines cool may have deteriorating crankshaft position sensors. Using an oscilloscope to check the sensors' signals is a precise way of testing the equipment. Hall-type sensors require testing the ground signal and the reference voltage, while pick-up coil type sensors require checking the sensors' resistance. Technicians replace the sensors when the resistance is greater than or less than a vehicle's manual specifies.

Where is a crankshaft position sensor located on a 1995 Dodge Stratus ES V6 2.5L?

The crankshaft position sensor is located below the heater inlet/outlet tubes below the distributor. It is held in pace by a 10 mm nut. You will need to remove the speed servo mounted on the left fender. I found that it is easier to access it by removing the left front tyre and the splatter shield and go through the wheel well. 

Where is the crankshaft position sensor on a 1995 Dodge Avenger?

look directly under the air intake hose as it attaches to the carburator. Directly below it is the distributor. Directly below that is the crankshaft position sensor. Its a small plug with a connector on it entering the engine. When I pulled mine off the insulator that attaches to the end was gone. It cost around 70$ to buy.

Where is the crankshaft position sensor located on a 1995 Chrysler LHS?

On our 1994 LHS it is located on the passenger side of the engine down by where the transmission is bolted to it. I had to remove the air intake pipe and push it out of the way, squeeze my left arm down through the opening to the left of the strut almost to my elbow and follow the connector wires to the sensor. One 10mm socket removed the single bolt holding the sensor (a tight fit ). A quarter turn of the ratchet was enough to loosen the bolt so I could unscrew it with my fingers. Wiggle the old one out and replace. Takes about 15 minutes.

Crankshaft position sensor Troubleshooting

Solved Crankshaft Position Sensor Problem

The 99 3400 has two Crankshaft position sensors. we have the 24x sensor that measures 24 times per turn. this is right behind the crankshaft pulley. This sensor is responsible for RPMs and timing.
now my car was kinda sputtering every once in a while and sometimes the tack would get squirrel. but it would have maybe a 1 to 2 second time period when it wouldnt function correctly, then all would be normal, and this was only when i was at full running temp. ok so replaced it like two nights ago, and had to get new crank pulley unfortunatly for not using the right tool. so i have a new 24x sensor and crank pulley on. now tonight  started it up turned on the ipod... died... so now what could it be? ugh.... start her back up and start driving. rpm guage bounced a few times and she starts sputtering... then while dies. throw it in neutral, start it back up and keep going. now keep in mind the check engine light didnt come on... it blinked for bout a second when my tach bounced and then it shut back off. like if you blinked you would have missed it. over the period of driving home the car died 3 times on me. all times were under 4000 rpms. when i would stop at a stop sign it would be all good til i let off the brake, then sputter sputter die. now ASSUMING i havent changed the 7x sensor im guessing this may be the actual one i have to change.

However right after i changed the 24x sensor, my check engine light went off within the first 5 minutes of runtime, so i figured i fixed the issue...

without the functioning of the 7x sensor, the ignition system would fail, which may explain the dieing.

The 24x crank sensor only controls ignition timing up to 3000rpm. Above 3000rpm the pcm uses the 7x sensor to control timing, and I believe it always takes the rpm signal off this too (not 100% sure on that). I do know the tach signal for the gauge cluster comes straight from the pcm, so any tach issues and running issues will be the result of a sensor signal problem going to the pcm.

If you replaced the 24x sensor and the crank pulley, you need to get a crank position learn procedure done (known as a CASE learn). The only way to do this is with a tech2 at a dealership, or if you can find someone local with a DHP or HPtuner who will do it for you. There is no way to do it yourself. That may fix your issue... it may not. If it doesn't then it's possible it is a problem with the 7x sensor, but I would think it would have a dtc code for that. There may still be a code stored in the pcm but it just hasn't tripped the SES light yet, so you might want to get it checked for codes. If you do need to replace that sensor, it is on the back of the engine block (firewall side) above the oil pan and transmission. Kind of tough to get to, but you should be able to see it from under the car. Hope that helps a little.

Don't need to remove the oil pan or anything to replaced the 7x sensor. It's on the outside of the engine block. It's just kinda hard to get to since it's on the back and you've got the steering rack and transmission down there and the exhaust manifolds up top. It's the only thing plugged into the side of the block back there though so you can't miss it when you see it.

Where Is Pontiac Crankshaft Position Sensor Located.

I have taken crankshaft pulley/harmonic balance off and there are no wires or a sensor behind it there is only the timing cover plate. So where is the cps located? Also this car stalled going down the interstate and will not start since. There was no warning that it was going to stall. It did not over heat and all fluids were fine.

How To replace Crankshaft Position sensor

Testing the crankshaft position sensor

This work is for Grand Am & Alero 99+,
Cutlass 97-99, Malibu 97-00
With engines, 2.4L 4cyl, and or the V6 3.1 & 3.4L

-- Performing these tests will set a diagnostic trouble code and illuminate the service engine light.
- Clear the codes after performing these tests and or repairs.

The crankshaft position sensor provides the ignition module and PCM a crank position signal.
The ignition module uses the signal to determine the firing order for each cylinder.
The PCM uses the signal to control the ignition timing and calculate RPM’s.
The signal is also used by the On board diagnostic (OBD) system to detect misfires.

-- The 4cyl has one 7X crankshaft position sensor (CPS).
-- The V6 has two CPSs a 7X and a 24X.

The 7X, on the 4cyl is located on the front (radiator)side of the engine , you cant actually see the sensor because its inside the motor reading the crankshaft, and on the V6 its on the rear(firewall)side of the engine, the 24X is on the Crankshaft behind the harmonic balancer(Crankshaft Pulley).

Pic of 7X on 4 cylinder

7X on the V6

The 7X CPS is a magnetic inductive sensor triggered by 7 slots cut into a reluctor ring on the crankshaft.
The sensor tip is about .05 inches from the reluctor ring.
As the notches pass the sensor the magnetic field is changed producing a pulsating voltage signal 7 times (7X) per crankshaft revolution.

The 24X CPS sensor is a hall effect device triggered by an interrupter ring behind the crankshaft pulley.
This sensor produces on and off pulses as the 24 blades and windows of the interrupter pass through the magnetic field.
The ignition system won’t work if the PCM doesn’t receive a 7X signal.

To test the 7X sensor, disconnect the plug connector.
Theirs also two wires for this at the ignition control module.
- A purple wire and a yellow wire, they need to be tested in AC volts.
- When cranking over the engine it should read at least 200 millivolts, if not replace the 7X sensor.

The 24X is on the front of the engine (on the oil pan) beside the crankshaft pulley,
which reads the interrupter ring in the harmonic balancer.

24X on V6
pontiac crankshaft position center

First check for power from the PCM.
- Disconnect the plug in, connect the positive on the voltmeter to the red/white wire and the ground to the black wire terminal turn the key on and it should be 12vlts, if not check the wiring from the 24X to the PCM.

CPS wiring harness location
CPS Wiring Harness

To check for operation is a bit more involved, reconnect the plug in.
- Using a probe, back probe the light blue/black wire terminal of the CPS and connect the positive lead of the voltmeter to the probe and the negative to an engine ground.
- Turn the key on, it should be about 10 volts.
- Now rotate the engine slowly (by hand) with a breaker bar and socket on the crankshaft bolt.
- While reading the voltmeter it should read between 10 – 0 volts as the blades pass the interrupter ring passed the CPS.
- If it’s not with in those tolerances, replace the 24X CPS.

To make turning the engine over by hand easier, remove the spark plugs first.

Crankshaft position sensor replacement

Any time a CPS is replaced, you may have to do a learning procedure,
or the system might give a false Diagnostic trouble code (DTC).
If your car has thrown a DTC call a dealer, or other qualified tech for this procedure.

To replace the 7X sensor disconnect the wiring harness connector.
Remove the CPS mounting bolts and pull the sensor out of the engine block.
Replace the “O” ring lightly lube it with clean oil.
- Install in the reverse procedure.

To replace the 24X sensor remove the drive belt.
- Jack up the vehicle and support with jack stands.
- Remove the crankshaft pulley.
- Remove the bolt and sensor wiring harness retainer bracket.
- Remove the 24X CPS mounting bolts.
- Remove the sensor and pull out the wiring harness,
Paying attention to how and where the harness was routed.

Pontiac fuel pressure regulator Testing

How To Test fuel pressure regulator

I own a 2000 Pontiac Grand AM SE 4 cylinder two door. I have sparodic but continuing problems with my car not starting up after i have made mutliple stops shopping. When it does not turn over, I leave it for a half an hour and come back and it starts up. I have noticed that when I pop the hood and check the oil guage the engine is very hot. It seems when it cools down it starts. I have been told this problem is perhaps related to an oil sensor or perhaps oil pressure. The "Change Oil" indicator on the panel is always on, even after I have the oil changed.

You should check the fuel pressure regulator at the end of the fuel rail. There is a vacuum hose on it. Pull the vacuum hose off and check for raw fuel inside it. If there is raw fuel, replace the regulator. You might need to test this several times, or when the vehicle will not start. 

fuel pressure regulator testing

what can happen is the regulator will leak fuel into the cylinders flooding the engine and not allowing it to start until it dries. Check this first

Where is the oil pressure sending sensor located Pontiac Firebird?

The oil sending unit is located at the oil filter boss on the engine block. I will attach an image to make it easy to locate.

oil sending unit

When the oil and fuel gauge stopped working,did they both go out at the same time?

not at the same time. oil gauge went first and then there was quite a
period of time before the gas gauge did it.

The fuel gauge *may* have lost is ground or it is corroded. I can supply you with the ground location if you would like? the gauge works on resistance,at 0 ohms it reads empty at 90 ohms it would read full. with an open circuit or a bad ground it would of course peg it up above full. if you find that the ground is good most likely the fuel sending unit has failed.
On the oil gauge,it isn't uncommon when pulling the oil filter you can slip and damage the oil sender so that would bury the oil gauge because it works on the same resistance level as the fuel gauge.
