DTC codes / Volkswagen codes / P1470
P1470 on Volkswagen vehicles indicates that the engine control module has detected an electrical fault in the Leak Detection Pump (LDP) circuit, which is part of the evaporative emission control system. The computer monitors the LDP's electrical circuit for expected voltage or current and flags this code when the signal is out of range, indicating an open, short, or component failure.
Guidance is general and written for Volkswagen vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
