PRNDL Reverse Input Open Circuit

What does code B1628 mean?

The OBD-II diagnostic code B1628 is triggered when your vehicle's Engine Control Unit (ECU) detects an issue described as: "PRNDL Reverse Input Open Circuit".

Although it is a universal OBD2 code applicable to almost all modern cars (since 1996), how to fix it depends heavily on the brand. Repairing this fault is not the same on an Audi as it is on a Honda.
