Code P0653 Audi Description

This fault code is stored in the Engine Control Module (ECM) when a malfunction occurs with the sensor supply voltage circuit. The Engine Control Module outputs a 5-volt supply voltage to certain sensors. Many components share the same 5-volt supply. If fault codes exist for multiple components that operate with a 5-volt supply the wiring from the Engine Control Module and the Engine Control Module itself should be tested. Also, each component should be disconnected in turn to identify a faulty component pulling down the supply circuit. The Diagnostic Trouble Code (DTC) will set when the Engine Control Module has detected the sensor 5-volt reference circuit voltage is higher than expected.
