Code P1472 GMC Description
The P1472 GMC diagnostic trouble code (DTC) indicates that the Particulate Matter (PM) Sensor Signal Message Counter is incorrect. This code is typically found in diesel vehicles equipped with a diesel particulate filter (DPF) system. The PM sensor is responsible for monitoring the amount of particulate matter in the exhaust gases and providing feedback to the engine control module (ECM) for proper emission control.
Common Causes of P1472 GMC
- Faulty PM sensor
- Wiring or connection issues in the sensor circuit
- ECM software or hardware malfunction
- Exhaust system leaks or damage
- Contaminated DPF system
Symptoms of P1472 GMC
- Check engine light illuminated
- Reduced engine power
- Increased fuel consumption
- Rough idling or engine misfires
- Failed emissions test
How to Fix P1472 GMC
- Diagnose the issue by using a scan tool to retrieve the DTC and perform a thorough inspection of the PM sensor, wiring, and connections.
- Test the PM sensor's functionality by checking its resistance and signal output.
- Repair or replace any damaged wiring or connections in the sensor circuit.
- Clean or replace the PM sensor if it is found to be faulty.
- Reset the ECM and perform a regeneration process to ensure proper DPF function.
Cost to Fix P1472 GMC
