A P0601 code is a specific OBD-II trouble code that is associated with the Engine Control Module (ECM) or Powertrain Control Module (PCM) in Subaru vehicles. This code indicates a malfunction in the internal memory of the ECM/PCM, which could result in various issues with the engine’s performance and overall functionality.

Diagnosing and Fixing a P0601 Code
Diagnosing and fixing a P0601 code requires the expertise of a qualified mechanic or technician. They will use specialized diagnostic tools to retrieve the trouble code and perform further tests to pinpoint the exact cause of the issue. Once the cause is identified, appropriate repairs or replacements can be made to resolve the problem and clear the code.
