P2130
Throttle/Pedal Position Sensor/Switch F Circuit
Throttle / pedal position
Generic OBD-II
Medium
What it means
P2130 means the engine control module sees an out-of-range signal in the 'F' throttle/accelerator-pedal position sensor circuit. On drive-by-wire vehicles the ECM relies on this sensor to know how far the pedal is pressed; when the signal is faulty it often defaults to a reduced-power limp mode to keep the car controllable.
Medium
Can I keep driving? The car usually runs but may drop into reduced-power limp mode; drive gently and get it checked soon, since throttle response can become unpredictable.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced engine power / limp mode
- Poor or erratic throttle response
- Unstable idle or unexpected stalling
Common causes
Most likely first
- Faulty accelerator-pedal / throttle position sensor (circuit F)Likely
- Open, shorted, or chafed sensor wiringCommon
- Poor or corroded connector at the sensorCommon
- Dirty or carbon-filled throttle bore skewing the sensor readingLess often
- Faulty ECM (rare)Less often
How to diagnose & fix
Work through it in order
- Inspect the pedal/throttle position sensor connector and wiring for damage or corrosion.
- With key on, engine off, confirm a steady 5-volt reference and a good ground at the sensor.
- Check that the F-circuit signal sweeps smoothly as the pedal/throttle moves.
- Clean the throttle bore if carbon build-up is affecting readings.
- Replace the sensor if its signal is out of range; retest before condemning the ECM.
FAQ
Quick answers
Is it safe to drive with P2130?+
It's drivable, but the car may limp with reduced power and throttle response can be inconsistent. Keep speeds low and get it diagnosed promptly.
Can I just clear P2130?+
You can, but a genuine sensor or wiring fault brings it right back and can drop the car into limp mode again.
