Throttle Position Sensor: Adjustments
Throttle Position Sensor Circuit.
The TP sensor is not adjustable. The reading should be checked only when the TP 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.
