P0225 Code: Throttle/Pedal Position Sensor C Circuit Malfunction
🟠 Moderate severity · drivable
Drivable, but the computer may limit throttle or enter limp mode, so fix it soon.
What P0225 means
The computer detects an electrical fault in the third throttle or accelerator pedal position sensor circuit (C). These signals confirm how far the pedal is pressed, and a bad reading on circuit C can make the computer restrict throttle response for safety.
Symptoms
- Check engine light is on
- Reduced or no throttle response
- Possible limp mode
- Engine running rough or stalling
Common causes
- most common: Faulty throttle or pedal position sensor
- common: Damaged or shorted sensor wiring
- common: Corroded or loose sensor connector
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the throttle or pedal position sensor | Yes | $50–200 |
| Repair damaged sensor wiring | Mechanic | $50–150 |
| Clean and re-seat the sensor connector | Yes | $0–50 |
