Code P1472 2018 Chevrolet Silverado Description
The P1472 code indicates that the Engine Control Module (ECM) has detected an issue with the particulate matter sensor, specifically regarding the signal message counter. This sensor is integral to monitoring the levels of particulate matter (PM) in the exhaust system, particularly in diesel engines equipped with diesel particulate filters (DPF). The particulate matter sensor provides real-time data to the ECM, which uses this information to optimize fuel injection and exhaust gas recirculation, ensuring compliance with emissions standards and enhancing engine performance.
Common Causes of P1472 2018 Chevrolet Silverado
- Faulty Particulate Matter Sensor: The sensor itself may be malfunctioning due to wear or internal failure.
- Wiring Issues: Damaged or corroded wiring or connectors associated with the particulate matter sensor can lead to incorrect signal transmission.
- Software Glitch: An outdated or corrupted ECM software may misinterpret the signals from the particulate matter sensor.
- Exhaust System Blockage: A clogged DPF or exhaust system can affect the sensor's ability to accurately measure particulate matter levels.
- Contamination: Soot or other contaminants may interfere with the sensor's operation, leading to erroneous readings.
Symptoms of P1472 2018 Chevrolet Silverado
- Reduced Engine Performance: The vehicle may exhibit sluggish acceleration and decreased power output.
- Increased Exhaust Emissions: The vehicle may produce more visible smoke or emissions, indicating a potential failure in the emissions control system.
- Check Engine Light: The illumination of the check engine light on the dashboard, signaling a fault in the emissions system.
- Poor Fuel Economy: A noticeable drop in fuel efficiency may occur due to improper fuel management by the ECM.
- Limp Mode Activation: The vehicle may enter a reduced power mode to prevent further damage, limiting speed and acceleration.
How to Fix P1472 2018 Chevrolet Silverado
- Diagnostic Scan: Use an OBD-II scanner to confirm the P1472 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Inspect the wiring and connectors associated with the particulate matter sensor for signs of damage, corrosion, or loose connections.
- Sensor Testing: Test the particulate matter sensor using a multimeter or specialized diagnostic tool to determine if it is functioning within specifications.
- Software Update: If applicable, update the ECM software to the latest version to resolve any potential glitches affecting sensor readings.
- Replace Components: If the sensor is found to be faulty or the wiring is damaged, replace the particulate matter sensor or repair the wiring as necessary.
Cost to Fix P1472 2018 Chevrolet Silverado
The typical repair costs for addressing a P1472 code can range from $200 to $800, depending on the specific diagnosis and repairs needed. This estimate includes parts and labor, with the cost of a new particulate matter sensor generally falling between $100 to $300. Labor costs can vary significantly based on location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour; however, rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less. It is advisable to check local rates for a more precise estimate and to obtain multiple quotes to ensure a fair price for the repairs needed.
