CHECK ENGINE LIGHT ON A lit check engine light in a vehicle is indicative of one or more problems including faulty oxygen sensors, leaking hoses or manifolds, damaged fuel injector O-rings, a blown head gasket and a loose or damaged gas cap. A blinking check engine light indicates an emergency problem that requires repair. Dealing with a check engine light on your vehicle’s dashboard can be frustrating. While the little light is meant to warn you of a problem – what the problem exactly is can be a mystery. Somewhere inside your vehicle, something happened to trigger the light. Although you'll probably have to take your car to the shop to get the exact answer, there are a few things you can do immediately after seeing the "service engine soon" light turn on for the first time. The most common cause of a lit check engine light is a faulty or loose oxygen sensor. The oxygen sensor measures the oxygen content of a vehicle's exhaust, allowing the comput...

ENGINE WARNING LIGHTS ON BMW X3 E83 2007 - the three warning lights plus eratic speedo plus erratic radio volume. On any car if you get a check engine light or other fault light this typically means one or more of the sensors has failed or has a faulty connection. The fault can be something quite simple and nothing that’s going to stop the car to something quite major that will reduce engine power and possibly stop the engine. The ECU senses this and may put the car into 'limp home' mode which typically limits the revs and the amount of power available. Usually the car is safe to drive for a short distance as the mode is intended is intended to get you home without incurring any engine damage. The quickest route to repair is to have the car plugged into a diagnostic machine which will read off the fault code stored in the ECU (providing the light is still on at this point) and indicate which sensor has failed or whether the fault is more serious. You ...

Troubleshoot Other Warning Light(s) On Car Control Panel Temp Warning Light On Your engine is overheating. Stop driving immediately and turn the engine off. Continuing to drive risks causing expensive engine damage such as a blown head gasket, or cracked or warped cylinder head. Low oil pressure or loss of oil pressure can be caused by a low oil level in the crankcase, a worn or damaged oil pump, or worn engine bearings. Allow the engine to cool down for several hours before you attempt any further diagnosis. A hot engine can be very dangerous because of steam pressure inside the radiator and coolant reservoir. Do NOT attempt to add coolant until the engine has cooled down and the radiator cap or reservoir cap can be safely opened. Overheating can be caused by a low coolant level (check the radiator, water pump, and hoses for leaks), coolant leaks inside the engine (leaky head gasket or cracks in the head or block), a stuck thermostat, or a cooling fan that isn't worki...

Engine Warning Light Is On Today’s cars are controlled by a Powertrain Control Module (PCM), your engine’s computer. If you want to repair or modify your car’s performance, you need a scantool to communicate with the PCM. Symptoms: Check Engine Light on Poor Acceleration Poor Fuel Economy Rough Idle Probable Cause(s): Oxygen Sensors Codes (P0130 to P0167) EVAP Code (P0445) That pesky Check Engine Light, the “Malfunction Indicator Lamp” or “MIL” for short, is on because your vehicle’s computer self diagnosed a fault that could cause your vehicle’s emissions to increase. It doesn’t necessarily mean your vehicle is polluting – or has a serious problem – but it might. So the light is on to let you know something is amiss that needs your attention. Trouble is, you don’t know WHAT the trouble might be. It might be something and could lead to a break-down or cause expensive engine damage, or it might be something minor like a loose gas cap (yes, the on-board diagnostics o...

Engine Working Of Car Engine Helpful Information Engine's are designed to have any number of cylinders and are created in all sizes. The pistons are designed to fire consecutively to rotate the crankshaft inside the engine block. Motor oil is used to cool and lubricate internal engine parts including the crankshaft, camshaft, cylinders, pistons, piston rings, wrist pin, lifters, rock arm, followers, intake and exhaust valves, timing gears and chain. The oil then travels back into the oil pan creating a recirculation system. The oil pump determines the amount of oil pressure the engine will have via a pressure spring fitted into a relief valve of the pump. There are primarily two styles of valve train systems, "overhead cam" which consists of a camshaft mounted on top of the cylinder head, and  "in block" systems which consist of a camshaft mounted inside the engine block, designs to perform this action will vary depending manufacturer. The cylind...
