Code P1235 2010 Ford Fusion Description
The P1235 diagnostic trouble code (DTC) for a 2010 Ford Fusion indicates that the fuel pump control circuit is out of range. This means that the powertrain control module (PCM) has detected a voltage or signal from the fuel pump control module that is not within the expected range. The fuel pump control module is responsible for regulating the fuel pump's operation, ensuring that the correct amount of fuel is delivered to the engine at all times. When this control is out of range, it can lead to issues with fuel delivery, which can affect the vehicle's performance and efficiency.
Common Causes of P1235 2010 Ford Fusion
- Faulty wiring or connectors in the fuel pump control circuit.
- Malfunctioning fuel pump control module.
- Failing fuel pump.
- Issues with the powertrain control module (PCM).
- Electrical problems such as a blown fuse or relay related to the fuel pump.
Symptoms of P1235 2010 Ford Fusion
- Engine stalling or hesitation during acceleration.
- Rough idling or misfires.
- Difficulty starting the vehicle.
- Reduced fuel efficiency.
- Check Engine Light illuminated on the dashboard.
How to Fix P1235 2010 Ford Fusion
- Begin by conducting a thorough inspection of the fuel pump control circuit, checking for any damaged wiring or connectors. Repair or replace any faulty components as needed.
- Test the fuel pump control module to determine if it is functioning correctly. Replace the module if it is found to be faulty.
- Check the fuel pump itself for proper operation. If the fuel pump is failing, it will need to be replaced.
- Verify the functionality of the powertrain control module (PCM) and address any issues if necessary, such as reprogramming or replacing the PCM.
- Clear the diagnostic trouble codes from the PCM and perform a test drive to ensure that the issue has been resolved.
