ROFL!

Right - found one issue - didnt get any voltage from the Pin 2. Weird! I decided to further investigate, and found that I had miswired the sensor.

Ryan very kindly incorporated a new loom for the lamda which I didnt have before (ie power and signal) .

I had wrongly assumed that the two black wires were power and earth, and that the single white wire was the signal. Turns out that one of the black wires was signal, and the other two powered the heater.

I have corrected the fault now in the wiring, testing the polarity to pin 2 with a voltmeter (what I should have done in the first place!)

Tested again, and got basically fuck all still from the Pin 2.

I checked the lambda and found it to be deeply coated in thick oil (somewhat unsurprisingly!)

But I wonder if attaching the leads the wrong way round has done damage to the sensor as well ? (cant see why it would, but seeing as it aint working......

I have presumed that the ECU hasnt been damaged by this - dont see how it would be, and car still runs right except the usual probs most of which predate the loom change which is when this error first occurred.;

Any thoughts?
