Tps Sensor trouble.

Post by ficodecko »

My car started to act funny the other day, as in, it would just die while i was driving still in gear and everything, i looked at kpro to see if i could tell what was causing it. The TPS was reading 0 and never changed and when i went over 2k rpms in gear the car would shut the injector power off. Right now im running with NO TPS and it runs ok, every once in a while it will shut the injectors off but its driveable for the most part.


TPS reads 0
Injectors turn off (0ms) over 2k rpm

im wondering why we even need a tps sensor when map and rpm determine fuel trim, and if anyone has anyother ideas of how to disable the paramaters surrounding the TPS so it stops killing my fuel

The solution is to either fix your wiring to the TPS sensor or replace the TPS sensor itself so that it reads correctly. As you can already see it will not run correctly without it.

When you unplug the TPS the ECU goes into a 'backup mode' where it uses other sensors to estimate the TP. You need the TPS - disabling it is not the right approach.

Find and fix the TPS problem. If you have swapped out a known good TPS, then start looking at the wiring.

i already know whats wrong with the car, and i know how to fix it, time snow and a warm place (or even shelter) are keeping me from it, my question was about running with no tps, but i had an idea,
the wires that go to the tps sensor are what color and what do they do? and the one that goes into the ecu what pin is that

mmmmm... I've tried and doesn't work (with PRB-KPRO). Unplug the TPS and the car don't run :cry:
