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.
