For the Volkswagen P0122 fault code, you need to clean the throttle body or repair the throttle body wiring. Below are the relevant introductions to the two solutions: 1. Cleaning the throttle body: First, remove the intake hose to expose the throttle body, disconnect the negative battery terminal, turn off the ignition switch, straighten the throttle plate, spray a small amount of carburetor cleaner into the throttle body, and then carefully wipe the deep parts of the throttle body with a polyester cloth or high-density non-woven fabric. 2. Repairing the throttle body wiring: It is necessary to go to a professional auto repair shop for repairs. Remember not to attempt repairs on your own, as this may damage the car's wiring.
