Code P1472 2015 Chevrolet Silverado Description
The P1472 diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado 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 responsible for capturing and storing soot particles from the exhaust to reduce emissions. The Particulate Matter Sensor is a crucial component of this system as it monitors the amount of particulate matter in the exhaust gases.
Common Causes of P1472 2015 Chevrolet Silverado
- Faulty Particulate Matter Sensor: The sensor itself may be malfunctioning, providing incorrect data to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the sensor and ECM can disrupt the signal transmission.
- Software Glitch: An issue with the software programming of the ECM or sensor can cause the incorrect message counter.
- Exhaust System Blockage: A clogged DPF or exhaust system can impact the sensor's readings.
- Environmental Factors: Extreme temperatures or driving conditions can also affect the sensor's performance.
Symptoms of P1472 2015 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P1472 code is the illumination of the check engine light on the dashboard.
- Reduced Fuel Efficiency: A malfunctioning Particulate Matter Sensor can lead to inefficient regeneration cycles, causing the vehicle to consume more fuel than usual.
- Poor Engine Performance: The engine may experience a decrease in power and responsiveness due to incorrect data from the sensor affecting engine management.
- Increased Emissions: The vehicle may emit higher levels of pollutants due to the DPF system not functioning optimally.
How to Fix P1472 2015 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scan tool to retrieve the DTC and pinpoint the exact cause of the P1472 code.
- Inspect the Particulate Matter Sensor: Check the sensor for any physical damage or signs of malfunction.
- Test Wiring Connections: Inspect the wiring harness for any damage or corrosion, and repair or replace as needed.
- Perform Software Update: Update the ECM software to ensure proper communication with the sensor.
- Clean or Replace DPF: If necessary, clean or replace the DPF to ensure proper functioning of the entire system.
Cost to Fix P1472 2015 Chevrolet Silverado
The typical repair costs for addressing a P1472 code on a 2015 Chevrolet Silverado can range from $200 to $600, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.

2. What are the common symptoms of code P1472 on a 2015 Chevrolet Silverado?
Symptoms may include a check engine light, reduced fuel efficiency, decreased engine performance, or the diesel particulate filter (DPF) failing to regenerate properly.
3. What causes the P1472 code to appear on a 2015 Chevrolet Silverado?
Common causes include a faulty particulate matter sensor, wiring or connection issues, software glitches in the engine control module (ECM), or excessive soot buildup in the exhaust system.
4. Can I drive my 2015 Chevrolet Silverado with a P1472 code?
Driving with this code is possible but not recommended, as it may lead to further damage to the DPF system or reduced engine performance if the issue is not addressed.
5. How do you diagnose a P1472 code on a 2015 Chevrolet Silverado?
Diagnosis involves scanning for codes, inspecting the PM sensor and its wiring for damage or corrosion, checking for exhaust leaks, and verifying sensor data using a diagnostic tool.
6. How do you fix the P1472 code on a 2015 Chevrolet Silverado?
Repairs may include replacing the particulate matter sensor, repairing damaged wiring or connectors, updating the ECM software, or cleaning/replacing the diesel particulate filter.
7. How much does it cost to fix the P1472 code on a 2015 Chevrolet Silverado?
The cost varies depending on the repair, ranging from $150-$400 for a PM sensor replacement to $1,000+ if the DPF requires replacement.
8. Can a dirty diesel particulate filter cause a P1472 code on a 2015 Chevrolet Silverado?
Yes, excessive soot buildup in the DPF can impact the PM sensor’s functionality and trigger the P1472 code.
