In 2003, the automatic transmission four-eye polo, EPC fault light on, power off, speed 1000 rpm or more. No gas. What's wrong?

EPC fault light mainly reflects the fault of electronic throttle, indicating that there is something wrong with the throttle. Possible 1, mechanical failure, such as the damage of the electronic throttle motor and position sensor itself, resulting in the mismatch between the throttle opening and the actual expected opening; 2. Electronic failures, such as wiring problems, lead to computer signals inconsistent with reality, resulting in poor power.
