check engine light
my check engine light is on and the vehicle is idleing high approx. 1500 rpms could this be a throttle position sensor issue or some other sensor.
Have the codes scanned somewhere to find out more about the problem.
Most common cause would be a vacuum leak. Check all rubber hoses and look for damage. Its could be a idle air control valve but i doubt it. Is the check engine light on? and is there any codes present? As for it being the TPS highley unlikely. If you had a bad TPS it would run rough, and would throw a code for sure.
check your codes I actually have a bad idle control valve and a bad throttle position sensor so anything is possible make sure to have checked. my second oxygen sensor was reading bad due to a exaust leak so best to get codes read. you can do that at and auto zone or advanced auto. my engine light was on due to all these
