P0451 indicates an issue with the Evaporative Emission Control System Pressure Sensor Range/Performance. Diagnostic time is approximately 30 minutes at local shop rates. Repair time depends on whether the sensor or ECM (Engine Control Module) is faulty. Have you noticed any other symptoms or recent maintenance work? This could help narrow down the root cause.

Thanks for the clarification, Kev. The P045-1 code points to either a failing pressure sensor or an ECM issue. I'm hoping it's just the sensor—no recent work or other problems reported. Appreciate your help!
