Code P113E 2018 GMC Sierra Description
The P113E diagnostic trouble code (DTC) for a 2018 GMC Sierra indicates a problem with Exhaust Gas Temperature Sensor 4 not being plausible. This sensor is responsible for monitoring the exhaust gas temperature in the exhaust system. When the sensor detects an issue with the exhaust gas temperature reading, it triggers the P113E code. This can lead to various performance issues in the vehicle, as the engine control module relies on accurate exhaust gas temperature data to adjust fuel injection and timing.
Common Causes of P113E 2018 GMC Sierra
- Faulty Sensor: The exhaust gas temperature sensor itself may be faulty and not providing accurate readings.
- Wiring Issues: Corroded or damaged wiring connected to the sensor can cause communication problems and trigger the P113E code.
- Exhaust System Problems: Issues with the exhaust system, such as leaks or blockages, can affect the sensor's readings.
- Engine Control Module (ECM) Malfunction: A malfunction in the ECM can also lead to erroneous exhaust gas temperature readings.
Symptoms of P113E 2018 GMC Sierra
