Title: front 02 lamba sensors
Post by: pauls on 10 October 2015, 23:17:25

After having a quick session with TB and his tech 2 today he advised me that my front 02 sensors are lazy. I have been trying to get part numbers for them so i can get a couple. But i keep getting back to the rear sensors.

my question is are these the same thing just in different parts of the exhaust. If not does anybody have the corrdct part numbers.

Same other than different cable lengths on the 2.2 certainly, never changed any on a V6.

The 3.2 does appear to suffer from this, I had same issues on my 3.2. I put known good pair on my 3.2, sourced here from twig let, but they were still lazy.  :-\

Reset codes, they were fine. But on a cold start after a few mins it could trigger the EML. Plugging in when hot/warm they were fine from Tech2 data. The dash came out, that fixed the problem  :-X  ;D

I think new o2 sensors are silly money  :-\

Go to local motor factor, and buy, couple 4 wire lambda. NGK are good.

I don't think that's the cause of your problem, just something that I'd noticed.
