Title: Engine Management Light/Oxygen Sensor
Post by: beaker on 08 October 2007, 20:50:53

The engine management light has been intermittantly coming on and off for about a week :(.  While there seems to be no loss in performance while driving, idle seems lumpy.  Have carried out the 'paper clip' test and have two fault codes:

13 - O2 Sensor 1 lead interruption.
39 - O2 sensor circuit 1 volt High.

Looking underneath I can see two O2 sensors, one in each down-pipe.

Does anyone know which is Sensor 1 or circuit 1?

I think sensor 1 is bank one (1/3/5 cylinders)

I'm inclined to agree, I think it's the offside / drivers side
