Throttle Position Sensor: Adjustments
NOTE: This check should be performed only when throttle body or TPS has been replaced, or after the minimum air flow has been adjusted.
1.
Connect a digital voltmeter from the TPS connector terminal B (dark blue wire) to terminal A (black wire). Jumpers for terminal access can be
made using appropriate connectors. A Scan tool can also be used to read TPS output voltage.
2.
With the ignition ON, engine stopped, TPS voltage should be between .42 and .54 volts.
3.
If voltage is out of range, rotate the TPS until 0.48 +/- 0.06 volts are obtained.
4.
If above voltage limitation cannot be obtained, replace TPS.
5.
Remove the voltmeter and jumpers, reconnect the TPS connector to sensor.
