Title: 2.6 V6 02 Sensor
Post by: davetyni on 21 February 2011, 20:29:27

Good evening all
I have a engine management light on, on my 2002 2.6 V6  which the dealer tells me is a faulty 02 sensor. I have looked on the exhaust system only to find that there 4 sensors fitted, which is the 02 sensor? if they all are, how can I tell which one is faulty.

"Hello" and Welcome :)

tech questions best asked in "Omega help" as more of "them that know" read there than here .. :)

But the 2.6/3.2 all have 4 sensors and 4 cats. 2 "little" cats and 2 "main" ones, 1 of each in each downpipe. The sensors are either side of the little "pre-cats" and can give "false" readings quite frequently.

Moving the 2nd sensor to after the main cat  is one fix, another is to do a couple of tankfulls of premium fuel - esso, shell - rather than supermarket stuff as this can often "cure" the problem for a while.

You can do your own diagnostic check with the "pedal trick"

expect an 0420 and/or an 0430 error code.

Personally, when I get one of those I use my code reader to clear the fault and reset the light .. it usually stays out for about a year .. :)
