Throttle Position (TP) Sensor Adjust

The TPS is not adjustable. Each time the voltage drops below 1.25 volts and stops, the ECM assumes that this value is 0 throttle angle and measures percent throttle from this point on. Therefore no adjustment is necessary.

If the proper range cannot be attained, replace the sensor.
