Code P242D 2017 Chevrolet Silverado Description
The P242D code on a 2017 Chevrolet Silverado indicates a problem with the Exhaust Gas Temperature Sensor 3 Circuit High Voltage. This sensor is responsible for monitoring the exhaust gas temperature and sending the data to the engine control module. When the sensor detects a high voltage in the circuit, it triggers this diagnostic trouble code.
Common Causes of P242D 2017 Chevrolet Silverado
- Faulty Exhaust Gas Temperature Sensor 3: The sensor itself may be defective and require replacement.
- Damaged Wiring or Connectors: Corrosion, fraying, or disconnection in the sensor circuit can trigger the high voltage reading.
- Engine Control Module Issue: A malfunction in the ECM can also cause the sensor to report high voltage inaccurately.
- Exhaust System Leak: A leak in the exhaust system before the sensor can lead to erroneous temperature readings.
- Extreme Engine Conditions: Operating the vehicle at high temperatures or under heavy loads can potentially damage the sensor.
Symptoms of P242D 2017 Chevrolet Silverado
- 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.
- Reduced Fuel Efficiency: A malfunctioning Exhaust Gas Temperature Sensor 3 can cause the engine to run inefficiently, leading to decreased fuel economy.
- Poor Performance: The vehicle may experience a loss of power or rough idle due to incorrect fuel mixture ratios.
- Increased Emissions: A faulty sensor can result in higher emissions output, potentially causing the vehicle to fail emissions tests.
- Overheating: In extreme cases, a malfunctioning sensor can cause the engine to overheat due to improper combustion.
How to Fix P242D 2017 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble code and pinpoint the source of the problem.
- Inspect Wiring and Connectors: Check the wiring harness and connectors for any damage or corrosion. Repair or replace as needed.
- Replace Exhaust Gas Temperature Sensor 3: If the sensor is found to be faulty, install a new sensor following manufacturer guidelines.
- Clear Error Codes: After completing the repair, clear the error codes and reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the sensor is functioning correctly.
Cost to Fix P242D 2017 Chevrolet Silverado
