O2 Sensor Question
My 2003Eu STI has lunched it's o2 sensor (rear bank)
Subaru say there are 2 sensors in the downpipe, the 1st as the fuel ratio sensor, and the 2nd is the o2 sensor.
Bob Rawle's delta dash highlighted the rear bank o2 sensor as the one that is toast
Which one of these sensors is the rear bank one?
Cheers
PS Bob, if you read this I have sent you an email.

I may be wrong, but I thought 1 sensor was in the exhaust headers ("fuel ratio") and the other sensor ("O2") was in the short cat pipe AFTER the downpipe NOT in the downpipe?
I'm sure I'll be corrected though if i'm wrong

You have 3 in the exhaust 1 in the headers(fuel ratio).1 in the uppipe by the cat(egt sensor).and 1 in the middle section by the gearbox(lambda sensor).

Thanks guys.
Have spoke to dealer, explaining the delta dash error, and they tell me that this sensor was replaced the last time I took it in with CEL issues...so it cannot be that...
The fact that the "2nd bank" o2 sensor is triggering the CEL, and that delta dash is recording a zero voltage error, and Bob has mapped the limits correctly...then WTF is going on with my motor?
