P138A Fault Code: Understanding The Description And Troubleshooting Tips
The P138A fault code is related to the Glow Plug Control Module in your automobile.
The Engine Control Module (ECM) is responsible for monitoring this module. When the ECM detects that the Glow Plug Control Module is not functioning correctly, it sets the P138A code in the On-Board Diagnostic II (OBDII) system.
This code specifically refers to the Glow Plug Control Module Control Circuit RangePerformance. In simpler terms, the P138A code indicates that there is an issue with the control circuit of the Glow Plug Control Module. This module is responsible for managing the glow plugs in your vehicle, which are essential for starting the engine, especially in cold weather.
When the control circuit is not operating within the expected range or is not performing as it should, it triggers the P138A fault code. If you encounter this fault code, it is important to have it addressed promptly. Ignoring the issue could lead to difficulties starting your vehicle, particularly in colder temperatures.
A qualified mechanic will be able to diagnose the exact cause of the problem and perform the necessary repairs to ensure your Glow Plug Control Module is functioning properly again.
