P041C Ford Code - Exhaust Gas Recirculation Temperature Sensor 'B' Circuit Low
Quick Answer
The P041C diagnostic trouble code (DTC) for Ford vehicles specifically refers to a fault in the Exhaust Gas Recirculation (EGR) Temperature Sensor 'B' circuit being detected as low. Common causes include A faulty EGR Temperature Sensor 'B', Damaged wiring or connectors in the sensor circuit, Malfunctioning ECM. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P041C Ford Description
The P041C diagnostic trouble code (DTC) for Ford vehicles specifically refers to a fault in the Exhaust Gas Recirculation (EGR) Temperature Sensor 'B' circuit being detected as low. The EGR system plays a crucial role in controlling emissions by recirculating a portion of exhaust gases back into the engine's intake to reduce combustion temperatures and minimize the formation of harmful nitrogen oxides (NOx). The EGR Temperature Sensor 'B' is responsible for monitoring the temperature of the exhaust gases entering the EGR system.
Common Causes of P041C Ford
- A faulty EGR Temperature Sensor 'B'.
- Damaged wiring or connectors in the sensor circuit.
- Malfunctioning ECM.
- Issues with the EGR system, such as a clogged EGR valve or cooler.
- Corrosion or contamination affecting sensor operation.
Symptoms of P041C Ford
- Check engine light illuminated on the dashboard.
- Reduced engine performance or power.
- Rough idle or engine misfires.
- Increased fuel consumption.
- Failed emissions test.
How to Fix P041C Ford
- Begin by verifying the DTC with a scan tool and confirming the presence of the P041C code.
- Inspect the wiring and connectors in the EGR Temperature Sensor 'B' circuit for any damage or corrosion.
- Test the EGR Temperature Sensor 'B' using a multimeter to determine if it is functioning within specifications.
- Replace the EGR Temperature Sensor 'B' if it is found to be faulty, ensuring the new sensor is properly calibrated and installed.
- Clear the DTC codes from the ECM and perform a test drive to confirm the repair and ensure the check engine light does not reappear.
Cost to Fix P041C Ford
The typical repair costs for addressing a P041C code on a Ford vehicle can vary depending on the specific components that require replacement and the labor involved. Generally, the cost of replacing an EGR Temperature Sensor 'B' can range from $100 to $300, including parts and labor. Additional costs may be incurred if other components of the EGR system need attention. It's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's advisable to obtain quotes from multiple sources to ensure a competitive price.
