Re: 6 ohms and 0.45 volts?
Okay.... summats wrong here, or maybe I dont know how to read your postings....
CO < 0.30% Actual 2.86%
HC <200ppm Actual 258ppm
Lambda 0.97 to 1.03 Actual 1.07
I'm having a bit of a problem comprehending this. Is it that the actual Lambda reading is 1.07 which means you're running lean, but the CO reading is 2.86 which indicates you're running very rich. Can you explain to me whether actual means your cars readings and the figures before the actual readings is what it's supposed to be?
Passing a Danish MOT requires a Lambda figure between 0.97 and 1.029 and a CO reading not greater than 0,3. If I'm understanding this correctly something is wrong, and I'm suspecting a leak somewhere in the exhaust system. Since the Lambda isnt fluctuating between 0.2 and 0.85 volts (IE running in closed loop) The leak could be well before the lambda probe.
