Throttle Position Sensor: Adjustments

Throttle Position Sensor (TPS):

TPS is an auto zeroing type and cannot be adjusted.

^ Use a "Scan tool" to check TP sensor output voltage with throttle closed, should be under 0.85 volts. If over 0.85 volts, check for binding throttle shaft, or TP sensor lever. If all OK, replace TP sensor.
