How to solve Jetta King p 1639 fault code?

Hello, is there a problem: P 1639 accelerator position/accelerator pedal position sensor 1/2- range/performance.

The fault causes include the fault of the throttle position (TP) sensor itself or its circuit or connector, and the fault of the electronic control module (PCM or ECM). When this fault code occurs, after cleaning the throttle, the matching is completed. If this problem persists, it usually means that a new throttle valve needs to be replaced. I hope it can help you with your car problem, and ask the car master. 4S shop professional technician, 10 minutes to solve.
