P0228 Code: Throttle/Pedal Position Sensor C Circuit High Input
🟠 Moderate severity · drivable
Drivable, but the sensor reading is wrong, so throttle response may be limited — fix it soon.
What P0228 means
The third throttle or accelerator pedal position sensor (circuit C) is sending voltage that's too high. The computer sees an unexpected pedal position and may restrict throttle or set a limp mode to protect the engine.
Symptoms
- Check engine light is on
- Reduced throttle response
- Possible limp mode
- Engine surging or hesitation
Common causes
- most common: Faulty throttle or pedal position sensor
- common: Wiring shorted to power in the sensor circuit
- rare: Faulty engine computer (PCM)
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Replace the throttle or pedal position sensor | Yes | $50–200 |
| Repair wiring shorted to power | Mechanic | $50–150 |
Frequently asked questions
Can I drive with a P0228 code?
Yes, but throttle response may be limited. Fix it soon to avoid limp mode.
What is the most common cause of P0228?
A faulty position sensor, though a wiring short to power is also possible.
How much does it cost to fix a P0228?
Usually $50–200 for a new sensor, or $50–150 if wiring repairs are needed.
