FORD TPS SENSOR REPLACEMENT PART 2 TPS TEST 1:  Testing the 5 Volt Reference Signal 1 /  2 Previous image Enlarge Next image The very first test we'll do, is to make sure that the throttle position sensor (TPS) is getting power. As you already know, this power is in the form of 5 Volts DC and is provided by the PCM. This test (as all of the tests in this article) must be done with a multimeter, either digital or analog. Also, I recommend that the engine be at its operating temperature... since the heat accumulated by the TPS from the engine may help to find a stubborn glitch in the sensor. These are the steps: Remove any plastic covers that may be hiding the TPS from view and access. Put your multimeter in Volts DC mode (don't have a digital multimeter? Need to buy one? Click here to see my recommendations:  Buying a Digital Multimeter for Automotive Diagnostic Testing ). With the RED multimeter lead, and an appropriate tool, probe the...

Throttle Body Replacement Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes. 1 Open your hood and locate your engine's throttle body. Photo may not be specific to your vehicle 2 Remove the air intake duct at the throttle body. 3 Inspect the throttle body ports for carbon build up. Throttle bore wear is also common after long periods of time and throttle body assemblies will need to be replaced if worn 4 Remove the throttle cable from the throttle body control lever. Photo may not be specific to your vehicle 5 Disconnect any air or vacuum hoses from the throttle body. 6 Remove the throttle position sensor from the throttle body. 7 Remove the throttle body mounting screws and remove the throttle body assembly. Discard the old gasket and install a new gasket between the throttle body and manifold during installati...

Throttle Actuator - Bore Working Of Cars Throttle Body Helpful Information A throttle actuator is assembled with tamper proof bolts so it cannot be taken apart, if this unit fails it must be replaced, never use an actuator that has been tempered with. The throttle actuator design is sometimes referred to as a "drive-by-wire" system, which references the absence of a throttle cable directly connected to the accelerator, drive by wire vehicles use an accelerator position sensor (APS) located at the pedal arm. Easy guide on how an automotive engine throttle actuator and throttle body with IAC valve work, this information pertains to most vehicles. A throttle actuator and throttle body are generally the same part, the actuator is fully computerized (no cable) with no IAC (idle air control) valve. These devices control the volume or amount of air that enters the engine via the driver's accelerator pedal. Throttle Actuator A throttle actuator is held to ...
