Code P2472 GMC Description
The P2472 GMC code indicates a problem with the Exhaust Gas Temperature (EGT) Sensor 4 circuit in the vehicle's exhaust system. This sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. The EGT sensor helps the engine control module (ECM) adjust fuel delivery and timing to optimize performance and reduce emissions. An intermittent circuit issue with this sensor can lead to incorrect temperature readings being sent to the ECM, which can negatively impact engine performance and emissions control.
Common Causes of P2472 GMC
- Faulty EGT sensor
- Wiring or connection issues
- Corrosion or damage to sensor or connector
- ECM software or hardware malfunction
- Exhaust system leaks or damage
Symptoms of P2472 GMC
- Decreased fuel efficiency
- Reduced engine power
- Rough idling or stalling
- Hesitation during acceleration
- Increased emissions
How to Fix P2472 GMC
- Diagnose the issue by using a scan tool to monitor EGT sensor data and check for any stored fault codes.
- Inspect the EGT sensor and its wiring for any visible damage or corrosion. Repair or replace as needed.
- Check the connections to the EGT sensor and ensure they are secure and free of debris.
- Clear the fault code from the ECM using the scan tool and test drive the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying issues with the ECM or exhaust system components.
Cost to Fix P2472 GMC
The cost of repairing a P2472 GMC code can vary depending on the specific cause of the issue and the labor rates at the repair shop. On average, the parts for an EGT sensor replacement can range from $50 to $200, while the labor cost can be between $100 and $200. Overall, the total repair cost for this issue can be around $150 to $400. It's important to note that these estimates are general guidelines, and actual costs may vary based on the vehicle's make and model, as well as the location and specific repair shop rates.
