Frequently asked questions about U012E
What does U012E mean?
Lost Communication With Camshaft Position Control Module. The control module stopped receiving expected network messages from the Camshaft Position Control Module node on the vehicle communication bus.
Is U012E generic or manufacturer-specific?
U012E is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove U012E at file level?
Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U012E is removable in your case.
