I'm at work and don't have either hte car or Dialogy's to hand. Can someone please look up the Ho2 sensor for me on an F7R-710 and tell me if it has two or three wires?
I'm hoping it has three!
Cheers,
Mick |

Four... Bugger
ECU only has two. A Signal Input and a Switched Earth. I'm trying to find the Signal Earth and if you're saying there's a fourth wire what the hell is that?
Cheers anyway Dan and it looks like i'm gonna have to wait till I get home then and have a peer under the bloody car with a multi meter in hand. |

FPMSL at your secret code. I must remember to decode it before trying to wire up the new ECU then 
I was pretty sure that Renault would have used the smae common earth for the Ho2S as the MAP, IACV and Knock sensor. Just gotta make 4 wires fit 3 pins then which isn't too bad.
Cheers again |
