29427 Description And Summary : |
|---|
This something to do with the intake camshaft timing vacuum reservoir pressure sensor, circuit range / performance the system depends on oil pressure to switch between cam profiles secondary air injection pump-c-relay (j704), circuit short to b+ . So for next linear oxygen sensor exhaust bank 3 / common ground wire, open circuit is the final reason of the code. |
