The P12A8 fault code is related to the boost pressure sensor in your automobile. This code is triggered when the sensor detects that the pressure is too low.

During the shutdown phase of the control module, the diagnostic function checks the barometric pressure sensor, intake-manifold sensor, and the pressure sensor on the air-intake side of the throttle valve. It compares the readings from these sensors to determine if they are all measuring the same pressure.

If the boost pressure sensor indicates a pressure that is below the factory specifications, the ECM sets the P12A8 code.

When this fault code is present, it indicates that there may be an issue with the boost pressure sensor in your vehicle. It is important to address this issue promptly, as it can affect the performance and efficiency of your engine.

A qualified mechanic will be able to diagnose the exact cause of the low pressure and recommend the necessary repairs or replacements to resolve the issue.
