P0226 Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance

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.

Likely causes

Wear or dirt on sensor C or the second throttle body
Contact resistance at connector or wiring
Throttle dirty or sticking
Engine module or software

Symptoms

  • Check engine light on
  • Limp mode, reduced power
  • Jerking, poor throttle response
