Special Notes
- One faulty sensor can cause this DTC and drop the Sensor Voltage Supply MVB reading. Unplugging the front -or- rear wiring harness to eliminate 4 sensors at a time is advised during the diagnosis. Make sure to cycle the ignition off and back on before evaluating the MVBs. After the front -or- rear of the vehicle are determined to be problematic it is recommended to unplug the senors one at a time to see which one crashes the Sensor Voltage Supply MVB reading.
