Code P1406 2010 Ford Fusion Description
The P1406 diagnostic trouble code (DTC) for a 2010 Ford Fusion relates to the DPFE (Differential Pressure Feedback EGR) sensor circuit downstream hose. The DPFE sensor is a crucial component of the vehicle's EGR (Exhaust Gas Recirculation) system, which helps reduce emissions and improve fuel efficiency. The downstream hose connects the DPFE sensor to the EGR valve, allowing the sensor to monitor the pressure difference before and after the EGR valve.
Common Causes of P1406 2010 Ford Fusion
- Damaged or deteriorated downstream hose
- Hose blockages or restrictions
- Electrical issues in the DPFE sensor circuit
- Corrosion or loose connections in the sensor wiring
- Faulty DPFE sensor
Symptoms of P1406 2010 Ford Fusion
- Poor fuel economy
- Rough idling
- Hesitation during acceleration
- Engine stalling
How to Fix P1406 2010 Ford Fusion
- Begin by locating the DPFE sensor and downstream hose in the engine bay.
- Inspect the downstream hose for any signs of damage, leaks, or blockages.
- Test the DPFE sensor and sensor circuit using a multimeter to check for proper voltage and continuity.
- Replace the downstream hose if necessary, ensuring a secure and proper fit.
- Clear the DTC using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1406 2010 Ford Fusion
