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. P0225 is the general circuit fault of sensor C without telling low from high (those are P0227/P0228). Ford sets it when the digital sensor of the second throttle body has been faulty for more than 4 s and switches on the warning light and the powertrain fault lamp; communication faults of the sensor line have their own codes. The result is reduced power.

Likely causes

Sensor C or second throttle body faulty
Wiring or connector (supply, signal line)
5 V reference disturbed
Engine module

Symptoms

  • Check engine light and powertrain fault lamp
  • Reduced power
  • Rough idle, jerking
