Code P101E Chevrolet Description
The P101E Chevrolet diagnostic trouble code (DTC) specifically refers to the Glow Plug Control Module Temperature Sensor 3 Circuit High Voltage. This code indicates that there is an issue with the temperature sensor in the glow plug control module, which is responsible for monitoring the temperature of the glow plugs. The glow plugs are crucial components of a diesel engine's cold-start system, as they heat up the combustion chamber to facilitate easier starting in cold weather conditions. When the temperature sensor detects a high voltage reading that is outside of the expected range, it can lead to issues with the glow plug operation and potentially affect the vehicle's performance.
Common Causes of P101E Chevrolet
- Faulty glow plug control module temperature sensor.
- Wiring or connector issues in the temperature sensor circuit.
- Corrosion or damage to the temperature sensor.
- Electrical system issues affecting the sensor's voltage readings.
- Software or programming issues in the engine control module.
Symptoms of P101E Chevrolet
- Difficulty starting the engine, especially in cold weather.
- Reduced engine performance and power.
- Increased fuel consumption.
- Illumination of the check engine light.
- Rough idling or misfiring.
How to Fix P101E Chevrolet
- Diagnostic testing to confirm the specific cause of the high voltage reading.
- Inspect and test the glow plug control module temperature sensor.
- Check the wiring and connectors for any signs of damage or corrosion.
- Repair or replace any faulty components as needed.
- Clear the DTC and reset the engine control module to see if the issue persists.
Cost to Fix P101E Chevrolet
The typical repair costs for addressing a P101E Chevrolet code can vary depending on the specific cause of the issue. In general, the cost of replacing a glow plug control module temperature sensor can range from $100 to $200 for the part, with additional labor costs of around $100 to $200. However, it's essential to consider that diagnostic time and labor rates at auto repair shops can vary, so it's recommended to check with local shops for more accurate estimates.
