How many volts does a throttle position sensor send?
The throttle position sensor gets 5 Volts and Ground from the ECM. As the engine in your pickup or van idles (and the throttle plate is closed), the throttle position sensor sends the ECM a voltage signal of about 0.9 to 1 Volts.
How do you remove a throttle position sensor?
Remove the air cleaner and the air induction hose leading to the throttle body by undoing the clamps and pulling them off. Remove the electrical connector from the throttle position sensor by pulling the connector apart.
What is the voltage when the throttle is open?
As the throttle moves from its idle position, at around 0.5 s, the output progressively increases with increasing throttle opening. With the throttle at its fully open position, the output is around 3.7 V.
Where does the TPS go on a big bore throttle?
When you receive a Big Bore Throttle Body from LC Engineering, you will notice that you will need to remove and reinstall your throttle position sensor blade onto the new throttle body . The blade is what engages the TPS to the throttle shaft.

What should I do if my throttle position sensor fails?
This is intended to at least allow a driver to get off a busy highway in a safer manner. Once the TPS begins to fail, even partially, you’ll need to replace it right away. Replacing the TPS will include clearing relevant fault codes, and may require software reprogramming of the new TPS module to match other engine management software.
How do you adjust the throttle position on a car?
1. Loosen the jam nut and unscrew the throttle stop screw all the way so that the throttle blade closes fully against the throttle body itself. 2. Turn the stop screw back in until it just touches the linkage, then turn in ¼ turn more. This extra ¼ turn keeps the throttle blade from sticking against the inner bore of the throttle body. 3.

What does the accelerator pedal position sensor do?
The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator.
How is pedal position converted to signal return?
There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM.
How can I check the voltage of my accelerator pedal?
With a voltmeter, probe the accelerator pedal sensor. It will have 5 volts for reference and next to it a varying signal. Turn the key on and slowly depress the pedal. The voltage should climb from .5 to 5.0 smoothly. Replace it if the voltage spikes or it has no voltage at the signal wire.
Where is the accelerator pedal position sensor located?
If you’ve done any type of research (before finding this tutorial), you probably already know that: The Accelerator Pedal Position sensor is inside the Accelerator Pedal Assembly. The Accelerator Pedal Assembly is not connected to the throttle plate via a cable (like in the good ole’ days).

What should the voltage be on the accelerator pedal?
With a voltmeter, probe the accelerator pedal sensor. It will have 5 volts for reference and next to it a varying signal. Turn the key on and slowly depress the pedal. The voltage should climb from .5 to 5.0 smoothly.
What happens to the app sensor when the pedal is depressed?
That APP Sensor 1’s signal increases as the accelerator pedal is depressed, from below 1.1 volt at 0% pedal travel (pedal at rest) to above 2.1 Volts at 100% pedal travel (pedal fully depressed). That APP Sensor 2’s signal decreases from above 3.9 Volts at 0% pedal travel to below 2.9 Volts at 100% pedal travel.
