Which sensor is the lambda, and which one is 02?
same one
same one…actually the one before cat is lambda, the one after is your 02 Sensor
? They are both called 02 sensors in our part of the world. They are interchangable. They do the same function for different uses. The first one monitors the mixture directly as it comes out of the cylinder head while the other monitors the efficiency of the catalyzer.
I agree with CIN, lambda and 02 are the same terminology.
The car has 2 - one for fuel control and one for reference.
true, but the reason i asked was because i was fitting a MIL eliminator kit, and obviously didnt want to wire it into the one which reads fuel mixture. All done now! cheers anyway guys
