Throttle Position (TP) Sensor Adjust

TPS Adjustment Check:






The TPS is not adjustable. The the reading should be be checked only when the TPS sensor or throttle body has been replaced or minimum idle air rate has been adjusted. To check the TPS reading connect a digital volt ohmmeter to the dark blue and black wires in the sensor harness. Take reading with key "ON" engine "OFF". A scan tool may also be used for this test.
