Code C2774 Mercury Description
The C2774 diagnostic trouble code (DTC) for Mercury vehicles refers to a Pedal Travel Sensor Plausibility Failure. This code indicates that there is a discrepancy between the signals being sent by the accelerator pedal position sensor and the brake pedal position sensor. The vehicle's electronic control module (ECM) uses these signals to determine the driver's intended actions and adjust various systems accordingly.
Common Causes of C2774 Mercury
- Faulty accelerator pedal position sensor
- Faulty brake pedal position sensor
- Wiring or connection issues between the sensors and the ECM
- Corrosion or damage to sensor connectors
- ECM software malfunction
Symptoms of C2774 Mercury
- Hesitation or lack of response when pressing the accelerator pedal
- Inconsistent or jerky acceleration
- Difficulty maintaining a steady speed
- Illumination of the check engine light
- Decreased fuel efficiency
How to Fix C2774 Mercury
- Begin by conducting a thorough inspection of the accelerator pedal position sensor, brake pedal position sensor, and their respective wiring and connections.
- Test the sensors using a multimeter to check for proper voltage output and resistance.
- Replace any faulty sensors or damaged wiring as needed.
- Clear the DTC from the ECM's memory using a diagnostic scan tool.
- Test drive the vehicle to ensure that the issue has been resolved and that the sensors are sending accurate signals to the ECM.
Cost to Fix C2774 Mercury
The typical repair costs for addressing a Pedal Travel Sensor Plausibility Failure can range from $200 to $500, including parts and labor.
