Where is the TPS sensor on a 97 S10-Blazer, LT model, W VIN, 4.3 Vortec 4 X 4 ? I looked in my Haynes manual and the pictures just don't match. I have had hard shift problems between 1st and 2nd and I'd like to change the TPS sensor. Any help would be welcome.

Test it first. ~0.5V at closed throttle, ~4.5V at wide open throttle, and a smooth transition from closed to open and back to closed.

The TPS is located on the driver side of the throttle body on the end of the throttle shaft. It is held in by two torx screws (possibly tamper-proof torx). It will be an all plastic sensor with a 3 wire electrical plug.

 

Thanks for the tip, I appreciate.
