Hi run the "My Naff Code Reader" on my V6 and was wondering about the block reading for the 02 sensor.  The engine had only done a short trip before plugging in.

Could this be a failing sensor?

[Marks DTM Calib]

Certainly no great evidence of one, biggest issue is the readings were taken before the engine was up to temperature so the system is not in closed loop, hence the O2's are doing nothing 

[TheBoy]

O2 Sensor Loop 1,Open
O2 Sensor Loop 2,Open

Wait until these go CLOSED, then check again.

Thanks

[TheBoy]

Are they both going rich/lean at about 0.5 - 1Hz?

B2 BLM looks low. Is EGR leaking?  Any other air leaks?

[valliant1972]

Its has a new EGR fitted. Ive checked all over for leaks and found nothing. All pipes are good. Replaced all the Orings to the plenum after Vauxhall left one crushed and sticking out. Also which side is bank 2?

Thanks
