check engine light

[katt68]

i posted an earlier question on here about the check engine light coming on . i have tried to read the codes myself but am having a hard time disphering the info. i think it is the throttle position sensor. is there any way of checking it or cleaning it? also, i am in nova scotia canada, you guys have said pep boyss and stuff do free code readings, anyone know of any places/shops in canada that do the same?

You can check the TPS by hooking up an analog voltmeter and looking at the voltage output while moving it through its range. You are looking for a smooth change of the needle on the voltmeter which matches the movement of the TPS. Jerks or dropouts to 0 volts point to a problem with the TPS.

There is no way of cleaning it that I'm aware of.
