The cost of fixing this code varies depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. These factors are influential in determining the overall cost of fixing the U0072 fault code.

The U0072 fault code is related to the Controller Area Network (CAN) bus system in a vehicle. CAN bus is a standard used to connect automotive devices without a host computer.

The CAN bus uses two wires for communication, CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V.

The U0072 code sets when the vehicle communication bus ‘E’ (-) is shorted to bus E (+). This fault code indicates that a supervised periodic message that includes the transmitter device availability has not been received. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise.
