P0229 Code: Throttle/Pedal Position Sensor C Circuit Intermittent
🟠 Moderate severity · drivable
Drivable, but the throttle signal drops in and out, so response may be erratic — fix it soon.
What P0229 means
The third throttle or accelerator pedal position sensor (circuit C) is sending a signal that comes and goes. An intermittent reading makes the computer unsure of pedal position, which can cause sudden changes in throttle response.
Symptoms
- Check engine light is on
- Intermittent loss of throttle response
- Sudden hesitation while driving
- Possible limp mode
Common causes
- most common: Loose or corroded sensor connector
- common: Damaged wiring that opens or shorts intermittently
- common: Faulty throttle or pedal position sensor
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Clean and re-seat the sensor connector | Yes | $0–50 |
| Replace the throttle or pedal position sensor | Yes | $50–200 |
| Repair damaged sensor wiring | Mechanic | $50–150 |
Frequently asked questions
Can I drive with a P0229 code?
Yes, but throttle response can drop out at any moment. Fix it soon for safe driving.
What causes an intermittent P0229 code?
A loose or corroded connector, damaged wiring, or a failing position sensor that loses contact.
How much does it cost to fix a P0229?
Often $0–50 if cleaning the connector works, or $50–200 for a new sensor.
