Throttle/Pedal Position Sensor F Maximum Stop Performance

Where it lives

For P2168, the part to look at first is the sensor named here.

Check these first

• A faulty throttle position sensor F circuit
• Corrosion or damage at the sensor F connector
• A sensor F installation or calibration fault
• A throttle body or throttle valve fault
• A failed idle air control valve

What to do next

1. Read the throttle position sensor F voltage on a scan tool
2. Move the pedal to the maximum stop and watch the signal
3. Clean the sensor F connector and wiring
4. Check the throttle body for carbon or sticking
5. Replace the throttle position sensor F if the signal is out of range
6. Clear the code and retest
