Code P2486 GMC Description
The P2486 GMC code indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit on Bank 2 Sensor 5. This sensor is responsible for measuring the temperature of the exhaust gases leaving the engine. The EGT sensor helps the engine control module (ECM) monitor and adjust the air-fuel mixture for optimal performance and emissions.
Common Causes of P2486 GMC
- Faulty EGT sensor
- Damaged wiring or connectors
- ECM malfunction
- Exhaust system leaks
- Engine overheating
Symptoms of P2486 GMC
- Decreased engine performance
- Poor fuel economy
- Rough idling or stalling
- Check Engine Light illuminated
- Increased emissions
How to Fix P2486 GMC
- Begin by diagnosing the EGT sensor using a multimeter to check for proper voltage and resistance.
- Inspect the wiring and connectors for any signs of damage or corrosion. Repair or replace as necessary.
- If the sensor and wiring are in good condition, the issue may lie with the ECM. Have the ECM tested and reprogrammed if needed.
- Clear the code from the ECM and test drive the vehicle to ensure the issue has been resolved.
- Monitor the EGT sensor readings periodically to ensure proper function.
Cost to Fix P2486 GMC
