This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with a sensor that measures how hot the exhaust gases are. It's like a thermometer for the car's exhaust system, and it's not working right.
The code P246E indicates an issue with the electrical circuit of the exhaust gas temperature sensor located on Bank 1, Sensor 4. This sensor helps monitor the temperature of the exhaust gases to ensure the engine is running efficiently and within safe temperature limits.
The exhaust gas temperature sensor measures the temperature of the exhaust gases leaving the engine. This information is used by the engine control module (ECM) to optimize engine performance and emissions. A fault in the sensor's circuit can lead to incorrect readings, affecting engine operation and emissions control.
• Check Engine Light illuminated
• Poor fuel economy
• Possible engine performance issues
• Faulty exhaust gas temperature sensor
• Wiring issues such as shorts or open circuits
• Connector problems or corrosion
Bank 1: The side of the engine where cylinder 1 is located.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for damage or corrosion
• Test the exhaust gas temperature sensor for proper operation
• Replace the faulty exhaust gas temperature sensor
• Repair or replace damaged wiring or connectors
• Clear the code and test drive to ensure the issue is resolved
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance and inspection of exhaust components
• Ensure proper installation of sensors
• Use quality replacement parts
Sensor Issue
• Address the issue promptly to prevent further damage
• Consult a professional mechanic if unsure
• Avoid driving the vehicle under heavy load until repaired
Check with the vehicle manufacturer for warranty coverage on emission-related components.
This code has become more common with the increased use of exhaust gas temperature sensors in modern vehicles for emissions control.
Moderate – While not immediately critical, it should be addressed soon to prevent potential engine or emissions issues.
Driving with a faulty exhaust temperature sensor can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The exhaust gas temperature sensor is typically located in the exhaust system, near the catalytic converter or turbocharger, on Bank 1.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor engine performance and increased emissions, potentially causing further damage.
Q: Can I drive my car with this code?
A: While you may still be able to drive, it's best to address the issue soon to avoid potential engine damage.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
