Code P1472 2017 GMC Sierra Description
The P1472 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates that the Particulate Matter Sensor Signal Message Counter is Incorrect. This code is specifically related to the diesel particulate filter (DPF) system in the vehicle. The DPF is designed to capture and store soot particles from the exhaust gases to reduce emissions. The Particulate Matter Sensor is responsible for monitoring the efficiency of the DPF by measuring the amount of particulate matter in the exhaust stream.
Common Causes of P1472 2017 GMC Sierra
- Faulty Particulate Matter Sensor: The sensor itself may be malfunctioning and providing inaccurate readings to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the sensor and ECM can disrupt the signal message counter.
- Software Glitches: Software issues within the ECM or sensor calibration can lead to incorrect data being transmitted.
- DPF Problems: Issues with the diesel particulate filter, such as clogging or damage, can affect the sensor's readings.
Symptoms of P1472 2017 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Power: The vehicle may experience a loss of power or acceleration due to the incorrect signal from the Particulate Matter Sensor.
- Poor Fuel Economy: A malfunctioning DPF system can lead to decreased fuel efficiency as the engine may not be operating optimally.
- Increased Emissions: If the DPF is not functioning correctly, the vehicle may produce higher emissions than usual.
How to Fix P1472 2017 GMC Sierra
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the specific DTC and pinpoint the exact cause of the incorrect signal message counter.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test Particulate Matter Sensor: Test the sensor using a multimeter to ensure it is functioning correctly. Replace if necessary.
- Check DPF System: Inspect the DPF for any clogs, damage, or leaks that could be affecting the sensor readings.
- Clear Codes and Test Drive: After making repairs, clear the DTC from the ECM memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1472 2017 GMC Sierra
The cost of repairing a P1472 code on a 2017 GMC Sierra can vary depending on the specific cause of the issue. In general, the cost of replacing a faulty Particulate Matter Sensor can range from $200 to $500, including parts and labor. If wiring repairs are needed, additional costs may apply. It is recommended to consult with a professional mechanic or dealership for a more accurate estimate based on the specific diagnosis and repair requirements. Keep in mind that labor rates can vary between different auto repair shops, so it's advisable to inquire about rates in your local area.
