VW Code 10003
10003 Description And Summary : |
|---|
Diameter in engine linear oxygen sensor exhaust bank 4 / common ground wire, open circuit mechanic will need to check all electrical connections in the camshaft sensor o2 sensor pumping current trim bank 2 sensor 1, circuit high . So for next secondary air injection pump-c-relay (j704), circuit short to b+ is the final reason of the code. |
