I have read the Haynes explanation of the throttle position sensor, but still makes no sense to me. It tells the computer the position of the throttle? Does the PCM really need a sensor to determine this information? I would think the PCM would take care of the air/fuel mix based on what the throttle was doing. How does a bad TPS manifest itself? symptoms? can the PCM function without it? besides the check engine light being on all the time. I unplug mine and it doesn't seem to make a difference.
