Does anybody know how to adjust TPS?I know I need to use ohm meter to check the voltage but I'm not sure which connector I should hook it up to. Also I need to know the range of voltage.

Thanks!

Dr. John mentioned that my TPS might be bad or out of adjustment on my 90 240SX so, I too am curious on how to check those two things. My service manual doesnt go that far in depth. It doesnt even explain how to remove or replace the TPS.

Then you need to acquire the Shop Manual, if you plan on working on the car!Most Nissan set the TPS at 0.40-0.44 VDC at warmed up idle throttle closed but the dynamic range is important in that >4.0 VDC is necessary to tell the ecu you are at [want] WOT.
