    Exclamation Lambda Wiring Diagram ?

    Does anyone have a wiring diagram on the lambda sensors ?

    I want to check all the wiring and need to know if the wires that go to the sensors go straight to the ecu or if they go to the fuse box first.

    They both utilise the same feed. F43 10AMP. Also using this feed is MAF/EVAP valve/SAI solenoid/SAI relay.

    So are you saying that they both go to a 12 amp fuse in the drivers side fuse box before going to the ecu?

    Also if their on the same feed as the MAF, could a dodgy MAF bring up the error code I'm getting tin this thread:
