P246E GMC Code - Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4
Quick Answer
The P246E GMC code refers to a fault in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 4. Common causes include Faulty EGT Sensor: The EGT sensor itself may be defective and not providing accurate temperature readings, Wiring or Connector Issues: Damaged wiring or connectors in the sensor circuit can prevent the EGT sensor from communicating with the ECM effectively, ECM Malfunction: A problem with the engine control module (ECM) can also trigger the P246E code. 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 P246E GMC Description
The P246E GMC code refers to a fault in the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 4. This sensor is responsible for monitoring the exhaust gas temperature in the vehicle's exhaust system. The EGT sensor plays a crucial role in ensuring the engine operates at the optimal temperature range, which is essential for maintaining performance, fuel efficiency, and emissions control.
Common Causes of P246E GMC
- Faulty EGT Sensor: The EGT sensor itself may be defective and not providing accurate temperature readings.
- Wiring or Connector Issues: Damaged wiring or connectors in the sensor circuit can prevent the EGT sensor from communicating with the ECM effectively.
- ECM Malfunction: A problem with the engine control module (ECM) can also trigger the P246E code.
- Exhaust System Leaks: Leaks in the exhaust system can affect the EGT sensor readings and trigger the code.
- Carbon Buildup: Accumulated carbon deposits on the sensor can interfere with its operation and cause a fault.
Symptoms of P246E GMC
- Check Engine Light: The most common symptom associated with the P246E code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The engine may experience a loss of power or decreased performance due to incorrect fuel injection and timing adjustments.
- Poor Fuel Efficiency: A faulty EGT sensor can lead to improper fuel mixture, resulting in reduced fuel efficiency.
- Increased Emissions: The vehicle may emit higher levels of pollutants due to the incorrect exhaust temperature readings.
- Rough Idle: The engine may idle roughly or inconsistently when the EGT sensor is malfunctioning.
How to Fix P246E GMC
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific fault code and pinpoint the exact cause of the problem.
- Inspect Wiring and Connectors: Check the wiring and connectors in the EGT sensor circuit for any damage or corrosion. Repair or replace as needed.
- Test EGT Sensor: Test the EGT sensor to ensure it is functioning correctly and providing accurate readings. Replace the sensor if necessary.
- Clear Fault Code: Once the repairs are made, clear the fault code from the ECM memory and reset the Check Engine Light.
- Test Drive: Take the vehicle for a test drive to ensure the issue has been resolved and the Check Engine Light does not reappear.
Cost to Fix P246E GMC
The typical repair costs for addressing the P246E code can vary depending on the specific cause of the issue. In general, the cost of replacing an EGT sensor can range from $100 to $300, including parts and labor. However, if the problem is related to wiring or ECM issues, the repair costs can be higher.
