172 ph1 intermitent lambda

[Namos251]

Hello,

I was hoping someone may be able to help. I need to know which ecu pins are for the pre cat lambda. My ph1 has two lambda and the wiring diagram only lists 1 lambda I think. Unless they both wire into the same points?? Not sure if that would br possible.

Thanks

Neil

Thanks for that. Does this mean my ph1 is wired the same as the ph2 due to having two lambda or would that be a bad guess?

The only way to 100% be sure is to check the pins match the wires on the end of the sensors . You’ll have to check continuity I’m afraid

same lambda phase 1 and 2. it's just a generic 4 wire.

Cheers for the replies guys. I've decided to pay someone to do it. Don't fancy playing with the loom with so much trial and error involved.

What you attempting to do anyway with the lambdas?
