Code P242B Description
The P242B diagnostic trouble code (DTC) refers to the Exhaust Gas Temperature Sensor Circuit Range/Performance Bank 1 Sensor 3. This code indicates that there is an issue with the exhaust gas temperature sensor located in bank 1 sensor 3 of the vehicle's exhaust system. The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine. This information is crucial for the engine control module (ECM) to adjust fuel delivery and other parameters to optimize engine performance and emissions.
Common Causes of P242B
- Faulty exhaust gas temperature sensor
- Wiring or connector issues in the sensor circuit
- Exhaust leaks near the sensor
- ECM software or programming issues
- Sensor contamination or buildup
Symptoms of P242B
- Check Engine Light illuminated on the dashboard
- Reduced fuel efficiency
- Engine misfires or rough idle
- Increased emissions
- Loss of power or acceleration
How to Fix P242B
- Begin by diagnosing the specific cause of the issue using a scan tool to read the DTC and testing the exhaust gas temperature sensor.
- Inspect the wiring and connectors for any damage or corrosion, repairing or replacing as necessary.
- Clean the sensor and its surroundings to remove any contamination that may be affecting its performance.
- If the sensor is faulty, replace it with a new one and reset the ECM to clear the DTC.
- Test drive the vehicle to ensure the issue has been resolved and the check engine light does not reappear.
Cost to Fix P242B
The cost of repairing a P242B DTC can vary depending on the specific cause of the issue and the labor rates in your area. Generally, the cost of replacing the exhaust gas temperature sensor can range from $100 to $300, including parts and labor. Additional costs may apply if wiring or connectors need to be repaired or replaced. It is recommended to consult with a trusted auto repair shop for a more accurate estimate based on your vehicle's make and model.
