P2469 GMC Code - Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 3
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 3, Exhaust Gas Temperature Sensor Bank 2 Sensor 3 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 Sensor 3 circuit poor electrical connection. 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.

1. What does the OBDII code P2469 mean for a GMC vehicle?
P2469 indicates an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit High on Bank 2 Sensor 3, meaning the sensor is reporting a voltage higher than expected.
2. What are the common symptoms of code P2469 on a GMC?
Symptoms may include a check engine light, reduced engine performance, poor fuel economy, or the vehicle entering limp mode.
3. What causes the P2469 code to trigger?
Possible causes include a faulty EGT sensor, damaged wiring or connectors, a short circuit, or excessive soot buildup in the exhaust system.
4. How do I locate Bank 2 Sensor 3 on my GMC?
Bank 2 refers to the side of the engine opposite the #1 cylinder, and Sensor 3 is typically located farther downstream in the exhaust system, near or after the catalytic converter.
5. Can I drive my GMC with the P2469 code?
Driving with this code is not recommended, as it can lead to increased emissions, poor engine performance, and potential damage to the exhaust system.
6. How is the P2469 code diagnosed?
A mechanic will use a scan tool to confirm the code, inspect the EGT sensor and wiring for damage, and perform voltage and resistance tests on the affected circuit.
7. How do I fix the P2469 code on my GMC?
Common fixes include replacing the faulty EGT sensor, repairing or replacing damaged wiring, and cleaning soot buildup in the exhaust system.
8. How much does it cost to repair the P2469 code?
The cost varies depending on the issue, but replacing an EGT sensor typically ranges from $150 to $300, including parts and labor.
9. Can a dirty exhaust system cause the P2469 code?
Yes, excessive soot buildup can interfere with the EGT sensor's readings, potentially triggering the code.
10. How can I prevent the P2469 code from recurring?
Regular maintenance, including cleaning the exhaust system and ensuring proper fuel quality, can help prevent issues with the EGT sensor.
