its the post cat sensor mate, and it may be buggered, check the connections and give it a good clean, but it may be on its way out

Disconnect the sensor and measure the resistance of the heater circuit in the sensor. If it's too high, the sensor needs to be replaced. If it's in spec, you've got a problem with the wiring between there and the ECU or a connector in the wiring.

Any idea what its ment to be?
Iv got custom code map and i know one of the lambda probes is turned off through the map, dont supose anyone knows wich one is turned off? iirc its the one after the cat but my be wrong.
Thanks for the replys
