When should I adjust my TPS?
The TPS should read between 4.0 and 5.5 volts. If the TPS reads outside of this range, the sensor must be adjusted. Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver.
How is a TP sensor used in an automatic transmission?
The PCM and the TCM share the output. This sensor’s signal, along with the vehicle speed sensor, is used by the TCM to provide optimal shift timing. Most TP sensors have extra pins for extra internal functionality. For this discussion, we look at three terminals and the sensor’s connection to the automatic transmission.
When to remove the TPS on a throttle?
When doing this, it is important that the TPS should be removed to prevent contamination (a primary cause for failure) and the throttle body-to-plenum gasket replaced. We strongly recommend cleaning your throttle body thoroughly before attempting any adjustment.
What should I check before adjusting my TPS?
This should be checked prior to any adjustment of the TPS. Crankcase vapors are commonly vented into the throttle body for re-introduction into the combustion process (by the Exhaust Gas Recirculation, or EGR, valve). These vapors can leave an oily residue on the back of the throttle pate and allow sludge and dirt to accumulate.
What happens if you set the TPS too far out?
Setting the transition too far out, would result in a sluggish throttle response, since the ECU would see a longer idle section on the TPS. If your TPS makes the idle transition (below 2300 to infinite) but it will do it at 0.90mm instead of at 0.85mm does this mean the TPS is bad?
