Frequently asked questions about U0612
What does U0612 mean?
Lost Communication With Intake Air Temperature Sensor 1 Bank 2. The control module stopped receiving expected network messages from the Intake Air Temperature Sensor 1 Bank 2 node on the vehicle communication bus.
Is U0612 generic or manufacturer-specific?
U0612 exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.
Can TuningBot remove U0612 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 U0612 is removable in your case.
