Question about 1998 GMC Jimmy
If the throtal Position Control Sensor went out on a 1998 GMC Jimmy how would it act, and where is it located on the vehicle?
The tps is ususally at the side of the throttle body opposite where the throttle cable / tv cable mount.
sometimes it won't start, run, or run erratically. there are ways of testing this unit (by output voltage) before you commit to buying a new one. to test it you will need a dvom (digital volt ohm meter).
just a note: straight from the book... "a broken or loose tps can cause intermitten burst of fuel from the injector and an unstable idle because the ecm thinks the throttle is moving."
