P1472 Buick Code - Particulate Matter Sensor Signal Message Counter Incorrect

Quick Answer

The P1472 Buick diagnostic trouble code (DTC) refers to the Particulate Matter Sensor Signal Message Counter Incorrect. Common causes include Faulty Particulate Matter Sensor: The sensor itself may be malfunctioning and providing incorrect data to the engine control module, Wiring Issues: Damage or corrosion to the wiring connecting the sensor to the engine control module can lead to signal errors, Engine Control Module Malfunction: Problems with the engine control module can prevent it from interpreting sensor data correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1472 Buick Description

The P1472 Buick diagnostic trouble code (DTC) refers to the Particulate Matter Sensor Signal Message Counter Incorrect. This code is specific to Buick vehicles and indicates a problem with the particulate matter sensor signal message counter, which is responsible for monitoring the level of particulate matter in the exhaust system. Particulate matter is a type of pollution emitted by vehicles that can be harmful to both human health and the environment.

Common Causes of P1472 Buick

  1. Faulty Particulate Matter Sensor: The sensor itself may be malfunctioning and providing incorrect data to the engine control module.
  2. Wiring Issues: Damage or corrosion to the wiring connecting the sensor to the engine control module can lead to signal errors.
  3. Engine Control Module Malfunction: Problems with the engine control module can prevent it from interpreting sensor data correctly.
  4. Exhaust System Blockage: A blockage in the exhaust system can interfere with the sensor's ability to accurately measure particulate matter levels.
  5. Software Issue: An issue with the software or firmware controlling the sensor and engine control module can cause communication errors.

Symptoms of P1472 Buick

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
  2. Reduced Fuel Efficiency: A decrease in fuel efficiency may occur due to the engine not running at optimal levels.
  3. Rough Idle: The engine may exhibit rough idling or hesitation when accelerating.
  4. Increased Emissions: The vehicle may fail emissions tests or emit more pollution than usual.
  5. Reduced Power: In some cases, the vehicle may go into a reduced power mode to prevent further damage.

How to Fix P1472 Buick

  1. Diagnose the Issue: Use a diagnostic scanner to read the trouble code and perform further testing to pinpoint the exact cause of the problem.
  2. Inspect Wiring: Check the wiring connecting the sensor to the engine control module for any damage or corrosion, and repair or replace as necessary.
  3. Test Particulate Matter Sensor: Test the sensor itself to ensure it is functioning properly, and replace if faulty.
  4. Check Exhaust System: Inspect the exhaust system for any blockages that may be affecting sensor readings.
  5. Update Software: If a software issue is suspected, update the software or firmware controlling the sensor and engine control module.

Cost to Fix P1472 Buick

The cost to repair a P1472 Buick code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, you can expect to pay anywhere from $200 to $500 for parts and labor to address this problem.
