Throttle/Pedal Position Sensor/Switch "F" Circuit
Code P2130 indicates a malfunction in the Throttle Position Sensor/Switch F circuit, which prevents the engine control module from accurately reading throttle position. This sensor is critical for fuel injection timing and air intake control, so circuit faults can cause rough running and poor drivability.
What You Might Notice
- Check Engine Light (MIL) illumination
- Rough idle or inability to idle smoothly
- Misfiring at idle or highway speeds
- Engine stalling after starting
- Poor throttle response and hesitation
Most Common Causes
- 1
Throttle Position Sensor (TPS) failure
The TPS potentiometer has failed or developed an open/short circuit internally. This is the most common cause of P2130.
- 2
Connector corrosion or loose connection
The TPS connector pins are corroded, damaged, or not fully seated, breaking the circuit signal path to the PCM.
- 3
Damaged or misrouted wiring harness
The TPS circuit wiring is chafed, pinched, or has internal breaks from poor routing or collision damage.
- 4
Sticking throttle return spring or stuck throttle
A stuck throttle plate or failed return spring prevents the sensor from reading proper throttle position changes.
How to Diagnose It
- 1
Check Throttle Position Sensor (TPS) failure — The TPS potentiometer has failed or developed an open/short circuit internally. This is the most common cause of P2130.
- 2
Check Connector corrosion or loose connection — The TPS connector pins are corroded, damaged, or not fully seated, breaking the circuit signal path to the PCM.
- 3
Check Damaged or misrouted wiring harness — The TPS circuit wiring is chafed, pinched, or has internal breaks from poor routing or collision damage.
- 4
Check Sticking throttle return spring or stuck throttle — A stuck throttle plate or failed return spring prevents the sensor from reading proper throttle position changes.
How to Fix It
- 1
Replace Throttle Position Sensor
Remove the old TPS from the throttle body and install a new sensor, ensuring proper installation and connector seating. Clear the code after replacement.
- 2
Inspect and clean TPS connector
Disconnect the TPS connector, clean corroded pins with contact cleaner or fine sandpaper, check for proper fit, and reconnect firmly. Retest for code return.
- 3
Repair or replace TPS wiring harness
Inspect the TPS circuit wiring for damage, chafing, or poor routing. Repair damaged sections with proper splicing and heat shrink or replace the entire harness if severely damaged.
- 4
Check throttle body and return spring
Inspect the throttle plate for sticking and verify the return spring moves freely. Clean carbon deposits or replace the throttle body assembly if the plate remains stuck after cleaning.
