TPS adjustment

[GNONYX]

Which one is more important, adjust the TPS idle reading of between 0.40 and 0.46 volts?
or
adjust until the sensor reads between 4.55 volts and 4.85 volts?

Idle reading is the way you set it. The voltage has to be below 0.5 volts.

Upper end voltage is not critical. You will achieve 100% power enrichment at around 3.9 volts so it can be off a bit on the big end.

I was always told idle is most important bc bad idle as it can cause SES light .. .4 -.46 like you said .42-.44 is ideal ...

here is decent thread

I prefer to use a round file vs a drill .. it is a balancing act and will drive you nuts GL

I always set mine to 42

I appreciate all comments
I do know how to adjust it, I just wanted to know is it the TPS is important or is the WOT voltage is or both work together

Loosen both screws, pull sensor forward, slightly snug screws and tap gently up or down from there to achieve target, once target is reached tighten screws. The voltage will be slightly higher with car running so compensate for it. For instance the key on engine off tps set to .40 at idle with engine running it normally will get closer to .42
