Hi folks!
I ordered myself an O2 sensor socket last week (see this thread!) (http://www.mr2roc.com/forum/viewtopic.php?t=3371&highlight=o2+sensor+color) which arrived last Friday.
So I thought I'd whip out my O2 sensors and check out my pre-cats (I also painted the heat shield while I was at it! - great guide Mark!) as I was travelling in the '2 to Stevenage on Saturday to stay with some mates who are at uni ('twas a great weekend - still feel a bit rough today s:oops: :oops: s:oops: s:lol: :lol: s:lol: )
Any way, I digress! Thankfully (touch wood) the pre-cats looked to be tip-top, but I noticed that the O2 sensor where a bit pink in colour - not the usual white s:? :? s:?
I remember reading in a thread (see here) (http://www.mr2roc.com/forum/viewtopic.php?t=3238&highlight=o2+sensor+color) that Liz's O2 sensors were pink and that this may mean that they're toast s:shock: :shock: s:shock:
So my question is; can anyone confirm what having pink O2 sensors means?
Should I clean them? - If so, what with? I have some Wynn's carb cleaner that I used to clean my MAF sensor with - I think it said on the back of the can that it was "suitable to use on O2 sensors" - so is this stuff okay to use?
The car seems to be a-symptomatic (well from what I can tell s:roll: :roll: s:roll: s:lol: :lol: s:lol: ).
Any advice will be greatly appreciated! s8) 8) s8)
Yes clean them, when i've done mine i used the same stuff you've got with no problems.
Excellent, I'll whip 'em out tonight then! s:wink: :wink: s:wink: s:lol: :lol: s:lol:

Well what did you think I was talking about! s:oops: :oops: s:oops: s:lol: :lol: s:lol:
I just thought - Should I clean all 3 O2 sensors - so I don't banjax the readings the ECU uses to correctly fuel the car?
I think I may have noticed the third O2 sensor when I painted the manifold heat shield / checked the pre-cats; - is it at the back n/s corner of the engine bay, just after the main cat?
