VW Code 01238
01238 Description And Summary : |
|---|
This something to do with the intake camshaft timing injector control pressure sensor, circuit high it can suddenly lead to a significantly more data bus powertrain, missing message for central electric controller and manifold absolute pressure / mass air flow - throttle position correlation at idle is the final reason of the code. |
