P246E Chevrolet Code - Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4
Quick Answer
The P246E Chevrolet 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 malfunctioning, providing incorrect temperature readings to the ECM, Wiring or Connector Issues: Problems with the wiring or connectors in the EGT sensor circuit can disrupt the signal transmission between the sensor and the ECM, ECM Malfunction: A malfunction in the engine control module can prevent it from receiving and interpreting the EGT sensor data correctly. 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 Chevrolet Description
The P246E Chevrolet 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, specifically in Bank 1, which typically refers to the side of the engine where the number 1 cylinder is located. Sensor 4 indicates that it is the fourth sensor in this bank. The EGT sensor plays a crucial role in helping the engine management system monitor and control emissions, fuel efficiency, and overall engine performance.
Common Causes of P246E Chevrolet
- Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Wiring or Connector Issues: Problems with the wiring or connectors in the EGT sensor circuit can disrupt the signal transmission between the sensor and the ECM.
- ECM Malfunction: A malfunction in the engine control module can prevent it from receiving and interpreting the EGT sensor data correctly.
- Exhaust System Damage: Physical damage to the exhaust system, such as leaks or blockages, can affect the EGT sensor's performance.
Symptoms of P246E Chevrolet
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience decreased power, acceleration, and overall performance due to incorrect temperature readings affecting the engine's operation.
- Increased Fuel Consumption: A faulty EGT sensor can lead to inefficient fuel combustion, resulting in higher fuel consumption.
- Emission Issues: The vehicle may fail emissions tests or produce higher emissions due to incorrect sensor readings affecting the engine's emissions control system.
How to Fix P246E Chevrolet
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific fault code and pinpoint the exact cause of the problem.
- Inspect EGT Sensor: Check the EGT sensor for any signs of damage or corrosion. Replace the sensor if necessary.
- Check Wiring and Connectors: Inspect the wiring and connectors in the EGT sensor circuit for any damage, corrosion, or loose connections. Repair or replace as needed.
- Reset ECM: Clear the fault code from the ECM's memory and reset it to see if the issue persists.
- Test Drive: Take the vehicle for a test drive to ensure that the Check Engine Light does not reappear and that the engine performance and emissions are back to normal.
