12V TPS Wiring Diagram

By unknown | Published: 24 Oct 2010


For TPS adjustment, Joe G. suggested using a potentiometer in the ground circuit. I decided to try it and It really gives a much better range of adjustment than elongating holes in the TPS body.

Here is a schematic drawing showing how to wire it.

Using the above circuit, adjusting the potentiometer adds resistance to the ground leg of the TPS which raises the voltage on the TPS signal wire.

I was able to change that voltage from the stock settilng of 0.5 volt to 1.2 and above.

I have it set at 1.2 at this time and it is working the way I like it.

    […] on another TPS. my question is i have seen in a few threads that you need a 5k linear pot, but here http://dieseldatabase.com/12v-tps-wiring-diagram/?id=54 it says to use either a 500-1000 ohm pot. am i okay using the 5k pot if i back it way down? […]
