P242D Dodge Code - Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 3
Quick Answer
The P242D diagnostic trouble code (DTC) for Dodge vehicles specifically indicates an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit High on Bank 1 Sensor 3. Common causes include Faulty EGT Sensor: The most common cause of a P242D code is a malfunctioning EGT sensor, which may be due to internal electrical issues or sensor degradation, Wiring Problems: Issues with the wiring harness connecting the EGT sensor to the ECM can also trigger this code, such as corrosion, frayed wires, or poor connections, Exhaust System Leaks: Exhaust leaks near the EGT sensor can lead to false readings and trigger the P242D code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P242D Dodge Description
The P242D diagnostic trouble code (DTC) for Dodge vehicles specifically indicates an issue with the Exhaust Gas Temperature (EGT) Sensor Circuit High on Bank 1 Sensor 3. This code is typically associated with diesel engines, where EGT sensors are crucial for monitoring exhaust gas temperatures to ensure optimal engine performance and emissions control. In this case, Bank 1 refers to the side of the engine that contains the number 1 cylinder, and Sensor 3 is the specific sensor within that bank.
Common Causes of P242D Dodge
- Faulty EGT Sensor: The most common cause of a P242D code is a malfunctioning EGT sensor, which may be due to internal electrical issues or sensor degradation.
- Wiring Problems: Issues with the wiring harness connecting the EGT sensor to the ECM can also trigger this code, such as corrosion, frayed wires, or poor connections.
- Exhaust System Leaks: Exhaust leaks near the EGT sensor can lead to false readings and trigger the P242D code.
- ECM Malfunction: In rare cases, a malfunctioning engine control module (ECM) can incorrectly interpret EGT sensor data and set the code.
Symptoms of P242D Dodge
- Check Engine Light: The most common symptom associated with the P242D code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Performance: Drivers may notice a decrease in engine performance, such as reduced power or acceleration.
- Poor Fuel Efficiency: A faulty EGT sensor can also lead to decreased fuel efficiency, resulting in more frequent trips to the gas station.
- Rough Idling: The engine may exhibit rough idling or intermittent stalling if the EGT sensor circuit is malfunctioning.
How to Fix P242D Dodge
- Diagnose the Issue: Begin by using a diagnostic scan tool to retrieve the specific trouble code and investigate the EGT sensor circuit's operation.
- Inspect Wiring and Connections: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test EGT Sensor: Test the EGT sensor's resistance and functionality to determine if it is faulty. Replace the sensor if needed.
- Clear Codes and Test Drive: After making repairs, clear the DTCs from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P242D Dodge
The cost estimate for repairing a P242D code can vary depending on the specific cause of the issue and the extent of repairs needed. On average, the cost of replacing an EGT sensor can range from $100 to $300, including parts and labor. However, if wiring repairs or ECM diagnostics are required, the total cost could increase significantly.
