TPS
 

Does anyone know how you go about calibrateing the TPS for 92 Bonneville?? I was told it should be between .39 - .42

If you loosen the two mounting screws, it'll rotate several degrees.

but how do you know when you got it in the right spot?

Do you have a scantool or multimeter? You move the TPS a little and either turn the key on and measure the voltage with the multimeter or see what it says on the scantool for TPS voltage.

got a multimeter I'll give it a try .....thanks !
