What does diagnostic code PO607 mean?

Answer 1

Diagnostic code P0607 refers to a malfunction in the Engine Control Module (ECM) or Powertrain Control Module (PCM). This code indicates that the control unit has detected an internal issue, which may be due to a faulty ECM/PCM, poor electrical connections, or other related components. It typically triggers a check engine light and may lead to drivability issues if not addressed. Diagnosis often requires checking for additional codes and inspecting the vehicle’s wiring and connections.
