Code P1120 2009 Ford Fusion Description
The P1120 diagnostic trouble code (DTC) for a 2009 Ford Fusion indicates that the throttle position sensor (TPS) is out of range. The TPS is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). When the TPS is out of range, it means that the signal being sent to the ECM does not align with the expected values, leading to potential issues with engine performance and drivability.
Common Causes of P1120 2009 Ford Fusion
- Faulty throttle position sensor
- Wiring or connector issues
- Dirty throttle body
- Malfunctioning engine control module (ECM)
- Electronic throttle control system malfunction
