P2472 Code - Exhaust Gas Temperature Sensor 4 Circuit Intermittent
Quick Answer
The P2472 diagnostic trouble code (DTC) refers to an issue with the Exhaust Gas Temperature (EGT) Sensor 4 Circuit Intermittent. Common causes include Faulty EGT Sensor: The EGT Sensor 4 itself may be faulty and need to be replaced, Wiring Issues: Damaged or corroded wiring connected to the EGT Sensor 4 can cause intermittent circuit problems, Poor Connection: Loose or poor connections between the sensor and the ECM can lead to intermittent circuit issues. 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 P2472 Description
The P2472 diagnostic trouble code (DTC) refers to an issue with the Exhaust Gas Temperature (EGT) Sensor 4 Circuit Intermittent. This sensor is responsible for monitoring the exhaust gas temperature in the vehicle's exhaust system. The EGT sensor provides crucial data to the engine control module (ECM) to ensure optimal fuel combustion and emissions control.
Common Causes of P2472
- Faulty EGT Sensor: The EGT Sensor 4 itself may be faulty and need to be replaced.
- Wiring Issues: Damaged or corroded wiring connected to the EGT Sensor 4 can cause intermittent circuit problems.
- Poor Connection: Loose or poor connections between the sensor and the ECM can lead to intermittent circuit issues.
- ECM Malfunction: In rare cases, a malfunctioning ECM can incorrectly trigger the P2472 code.
Symptoms of P2472
- Check Engine Light: The most common symptom associated with the P2472 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A faulty EGT sensor can lead to incorrect fuel mixture, resulting in decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or hesitation when the EGT sensor is not functioning properly.
- Increased Emissions: A malfunctioning EGT sensor can cause the vehicle to produce higher emissions than usual.
How to Fix P2472
- Diagnose the Issue: Use a scan tool to retrieve the DTC and determine the specific cause of the intermittent circuit issue with the EGT Sensor 4.
- Inspect Wiring: Check the wiring harness connected to the EGT Sensor 4 for any signs of damage, corrosion, or poor connections. Repair or replace as needed.
- Test EGT Sensor: Test the EGT Sensor 4 using a multimeter to ensure it is functioning correctly. Replace the sensor if it is faulty.
- Clear DTC: After completing the repair, clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2472
The cost of repairing a P2472 code can vary depending on the cause of the issue and the labor rates in your area. On average, the cost of replacing an EGT Sensor 4 can range from $100 to $300, including parts and labor. Additional costs may apply if wiring repairs or ECM diagnostics are needed. It's recommended to consult with a professional mechanic to get an accurate estimate based on your specific vehicle make and model. Labor rates at auto repair shops typically range from $80 to $150 per hour.
