Setting your tps sensor?

93ImprezaSFI · 08-30-2010, 03:18 PM

I would like to know how to set your tps sensor to the exact setting and what tools I need to do it with.

I just recently bought a new tps and I know I didn't set it right, I just did it by ear. My car runs like crap and I think that's the problem.

Fully closed the TPS should be 0.2-1.0 volts. The factory setting is .35v.

All you need is a philips head screwdriver and a mulitmeter with a thin lead to jam in the back of the connector to read voltage. A paperclip works nicely for this.

The red wire is the 5v reference signal, the black is the ground. The light green wire (pin 3) has the ECU signal on it. Take the reading off of that one for the output voltage.

I'm looking at newer wiring diagrams so the color of the signal wire may be different for your car.
