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

Quick Answer

The P2469 Chevrolet code indicates a problem with the exhaust gas temperature sensor circuit on Bank 2 Sensor 3. Common causes include Faulty Sensor: The exhaust gas temperature sensor itself may be malfunctioning, providing incorrect readings to the engine control module, Wiring Issues: Damaged or corroded wiring in the sensor circuit can cause intermittent connections or a high voltage signal, triggering the P2469 code, Connector Problems: Loose or damaged connectors in the sensor circuit can disrupt the signal between the sensor and ECM, leading to code activation. 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.
