Hi all.
The plug part of my lambda pulled off the other day exposing the wires. Now I've looked around and most lambda sensors have 2 white, a grey and one black wire. Mine is different. Black, red, grey and white. Anyone know which is which and which they marry up with on the loom?

Thanks

What year/model is your car? Does the plug/wires appear to be standard or did someone swap them out?

 

On an SPi, there are indeed 4 wires but they are black (ground), blue/red (lambda relay), blue/white (ECU 14), and blue/yellow (ECU 13).

You're going to have to test the sensor to know what each wire is for.

 

This might help
