Omega General Help / Engine Management Light/Oxygen Sensor
« 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?
