In this guide, you will find instructions on how to check the engine oil level on a Volkswagen.
The purge valve on Volkswagen vehicles is part of the Evaporative Emission Control (EVAP) system.
The main function of the purge valve (N80) is to capture fuel vapor from the fuel tank and return it to the fuel system so that it can be burned in the engine instead of being released in the air. The purge valve is short for the canister purge valve, but it may also be called the evap purge valve.
In this guide, we diagnose a Volkswagen Jetta that has a bad purge valve. We will look at the Diagnostic Trouble Code (DTC) triggered by a faulty purge valve on a VW, symptoms, and where the purge valve is located.
This valve opens on command by the Engine Control Unit (ECU) to purge fuel vapors from the charcoal canister into the intake manifold. The purge valve is also used to tests for vapor leaks by pulling a vacuum. When it fails, it causes fault codes such as P0441 or P0444 or other codes related to "evap system malfunction" pointing to a faulty N80 sensor.
On Volkswagen Jetta, Golf, CC, Passat, EOS, CC, etc., the purge valve is mounted on the engine's top or side, generally on the passenger side.
