2007 Volkswagen Passat Q&A

2007 Volkswagen Passat Question: What are codes P06742 and 2004

Check Engine light came on - Codes P0642 and 2004 - what do these mean and what are possible solutions? -
Answer 1
This is for an ECM short or poor electrical connection. The ECM may need replaced or there is a shorted sensor on 5 volt circuit. The 2004 code is for an intake manifold runner control bank 1 stuck open. This could be the cause of the ECM fault code. Check the manifold runner for a possible short. -
