Code P1120 2007 Ford Fusion Description
The P1120 code for a 2007 Ford Fusion indicates that the Throttle Position Sensor (TPS) is out of range. The TPS is a crucial component of the electronic throttle control system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal engine performance. When the TPS is out of range, it means that the signal being sent to the ECM is not within the expected parameters, which can lead to various issues with the vehicle's performance.
Common Causes of P1120 2007 Ford Fusion
- Faulty Throttle Position Sensor
- Wiring or connector issues
- Dirty throttle body
- ECM malfunction
- Mechanical issues with the throttle system
Symptoms of P1120 2007 Ford Fusion
- Rough idling or idle fluctuations
- Hesitation or lack of response when pressing the gas pedal
- Stalling or difficulty starting the engine
- Poor acceleration or loss of power
- Illumination of the Check Engine Light
How to Fix P1120 2007 Ford Fusion
- Begin by verifying the code with a scan tool to confirm the TPS is indeed out of range.
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as needed.
- Clean the throttle body to ensure smooth operation and proper TPS signal transmission.
- Test the TPS using a multimeter to check for proper voltage and resistance values.
- Replace the TPS if it fails the tests and recalibrate the new sensor to ensure accurate readings.
