P0226Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Sensor C is a third throttle or pedal position sensor whose role depends on the manufacturer. Ford uses it for the sensor of the second throttle body on engines with two throttles and digital (SENT) sensors; with other makes it can be a further pedal or throttle channel. P0226 is the plausibility fault: the signal of sensor C is electrically valid but does not match its partner sensor or the airflow model. No manufacturer using exactly this code was found – Ford does not report sensor C plausibility separately. The logic follows the sibling checks on sensors A and B (Bosch: more than 9 % deviation, Ford: more than 7 degrees). The result is limp mode with reduced power.
- What you may notice
- Check engine light on
- Limp mode, reduced power
- Jerking, poor throttle response
- Likely causes
- LikelyWear or dirt on sensor C or the second throttle body
- PossibleContact resistance at connector or wiring
- PossibleThrottle dirty or sticking
- RareEngine module or software
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €80 – €700
