Throttle/Pedal Position Sensor/Switch F Circuit
What does P2130 mean?
The P2130 code means the vehicle's onboard diagnostic system has detected: Throttle/Pedal Position Sensor/Switch F Circuit. This is a critical severity code.
Common Symptoms
- Reduced engine power
- Throttle response delayed or erratic
- Limp mode warning on dash
- Engine idle higher or lower than normal
- Check engine light on
Probable Causes (Ranked by Likelihood)
- Faulty throttle position sensor (secondary track on throttle body) Very High
- Damaged wiring or connector to TPS F circuit High
- Electronic throttle body TPS failure Moderate
- Corroded throttle body connector Moderate
- PCM input circuit failure Low
Step-by-Step Diagnostic Procedure
-
Monitor TPS F circuit voltage with scan tool -- should change smoothly as throttle opens and closes
-
Compare TPS F reading to TPS primary reading -- they should correlate (often inverse relationship)
-
Inspect electronic throttle body connector for corrosion or damage
-
Check for 5V reference and ground at throttle body connector
-
Replace electronic throttle body if TPS F signal is absent or erratic with good wiring
Frequently Asked Questions
Can I drive with code P2130?
Only short distances with caution. The PCM may enter reduced power mode since it cannot verify throttle position with the F circuit. Drive directly to a repair shop.
What is TPS circuit F?
Circuit F refers to the secondary throttle position sensor track on the electronic throttle body. Like the pedal, the throttle body has two position sensor tracks for redundancy. The PCM compares both to ensure the throttle is in the correct position.
Is TPS F part of the throttle body?
Yes. The F circuit TPS is integrated into the electronic throttle body and cannot be replaced separately. The entire throttle body assembly must be replaced if the sensor has failed.
