P2469 Code - Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 3

Quick Answer

The P2469 diagnostic trouble code (DTC) refers to an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit High on Bank 2 Sensor 3. Common causes include Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, providing incorrect temperature readings to the engine control module (ECM), Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can cause circuit high readings, Poor Electrical Connections: Loose or poor electrical connections at the EGT sensor or ECM can result in an intermittent high voltage signal. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2469 Description

The P2469 diagnostic trouble code (DTC) refers to an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit High on Bank 2 Sensor 3. This code indicates that the EGT sensor located after the diesel particulate filter (DPF) on bank 2 sensor 3 is detecting a higher than normal temperature. The EGT sensor is a crucial component in modern diesel engines as it measures the exhaust gas temperature to help regulate emissions and optimize engine performance.

Common Causes of P2469

  1. Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, providing incorrect temperature readings to the engine control module (ECM).
  2. Wiring Issues: Damaged or corroded wiring connecting the EGT sensor to the ECM can cause circuit high readings.
  3. Poor Electrical Connections: Loose or poor electrical connections at the EGT sensor or ECM can result in an intermittent high voltage signal.
  4. Exhaust System Blockage: A blocked DPF or exhaust system can cause high exhaust gas temperatures to be detected by the sensor.

Symptoms of P2469

  1. Check Engine Light: The most common symptom associated with the P2469 code is the illumination of the check engine light on the vehicle's dashboard.
  2. Reduced Engine Performance: The engine may experience reduced power, acceleration, and overall performance due to incorrect temperature readings from the EGT sensor.
  3. Increased Fuel Consumption: A faulty EGT sensor can cause the engine to run inefficiently, leading to increased fuel consumption.
  4. Black Smoke from Exhaust: An excessively high exhaust gas temperature can result in black smoke emanating from the exhaust pipe.

How to Fix P2469

  1. Diagnose the Issue: Use a diagnostic scan tool to identify the P2469 code and pinpoint the exact cause of the high voltage signal.
  2. Inspect EGT Sensor: Check the EGT sensor for any visible damage or signs of malfunction. Replace the sensor if necessary.
  3. Check Wiring and Connections: Inspect the wiring harness and electrical connections for any damage or corrosion. Repair or replace as needed.
  4. Clear Fault Codes: After repairing the issue, clear the fault codes from the ECM memory to reset the check engine light.
  5. Test Drive: Take the vehicle for a test drive to ensure that the repairs have resolved the P2469 code and that the engine is running smoothly.

Cost to Fix P2469

The typical repair costs for addressing the P2469 code can vary depending on the specific cause of the issue and the cost of parts and labor. In general, replacing a faulty EGT sensor can range from $100 to $300, while addressing wiring or connection issues may add additional labor costs. Overall, the total repair cost for this issue could range from $200 to $500, excluding diagnostic fees and taxes.
