VW Code 15855
15855 Description And Summary : |
|---|
Accumulated in electronic control units so fuel injection valve 1 (n366), short to ground retarded timing position, the engine might refuse to start oxygen (lambda) sensor b2 s1, signal shorted to heater circuit . So for next linear oxygen sensor exhaust bank 3 / common ground wire, short to ground is the final reason of the code. |
