How is the throttle position sensor used in a PCM?
The PCM uses this information to determine control of various output devices, such as the fuel injectors, transmission shift solenoids, etc. Basically, the throttle position sensor is a variable resistor. Its internal resistance and output signal voltage change in relation to throttle position.
When do I need to replace my throttle position sensor?
If your vehicle requires throttle position sensor adjustment, consult the factory repair information for the exact specifications. That’s what it takes to replace your throttle position sensor.
Can a bad throttle position sensor cause spontaneous acceleration?
Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn’t step on the gas. Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow.
Where is the throttle position sensor on a Honda Accord?
Step 1: Locate the sensor. The throttle position sensor is mounted to the throttle body on top of the engine. Step 2: Disconnect the negative battery cable. Disconnect the negative battery cable and set it aside. Step 3: Remove the sensor electrical connector.

How to replace idle air control valve ( IAC )?
First step is to remove spark arrestor and decorative plate below it. Next, remove cannon plug for either TPS or IAC. Here are plugs removed from both sensors: Here, the gray sensor is the new TPS: Reinstall cannon plug for whichever sensor you replaced, then reinstall spark arrestor/air filter and you’re done.
