My O2 sensor always reads 0.00v....so i guess this means its bust ?
Doesnt actually seem to have any effect on my driving, which is weird. Tried cruising and part throttle driving which is where i thought the O2 sensor was used, but the car was fine.

I think i will turn O2 feedback off anyway, as others have reported that it improves the drive.

So is it bust ? and why doesnt it effect anything else ?

.....just been out and checked an it is connected still. Wire is very taught though where it bends round the y pipe. Maybe the wire is bust.

No-one else had this problem ?

Does the PFC ignore the O2 sensor in part throttle ? Or is that what i would be turning off if i used the disable O2 sensor feedback option ?

The PFC does monitor O2 voltage and does display it.

Get a high impedance volt meter and measure the voltage on both sides of the connector.

sub-zero

cewrx7r1, should the o2 reading on the PFC change in the sensor check area? My voltage is always 0.01 even though my 3 wire sensor conected to the Halmeter a/f is always changing. Did the guy who installed in not hook up the wire to the PFC, and would this cause misfiring on high load?

Thanks

The PFC O2 reading should change just as it does at the sensor or AFR meter. Seems as if it is not connected to the PFC.
