Does anyone know where I can get an oxygen sensor wire extender? Or if one is even made for the car? I have an 03 TL-S, and the extension would be for the O2 sensor sitting on the Catalytic Convertor itself. Thanks in advance!

 

Excelerate has them I believe, he is a vendor on here.

 

whats up? are you installing a high flow cat and need to put in the `spark plug anti fouler` thing? or some secret mod?

excelerate would be my first call too- Josh is the cat man!
and probably not that far from you, he has a performance shop,,plus the speed parts biz

 

got a random tech hi flow, but the o2 wire doesnt reach, extended it for now but cutting and extending, but going to buy new o2s and dont wanna cut the new ones.

 

you will want to extend/protect the end of the o2 with the anti fouler device
I dont know about your exact product- speaking in general about hi flow cats and too much flow screws with readings

 

Agree with ^^^

step 0) buy harness from excelerate for $29
step 1) buy anti foulers at autozone (comes in pairs)
step 2) drill one anti fouler (1/2in)
step 3) connect anti foulers together
step 4) install o2 sensor in anti fouler onto cat.

 

had not heard the double trick,,just saw fsttyms1 pics of drilled out anti fouler

 

i will have to try this anti fouler thing, because it is throwing a p0420 code, and the yellow light in my face gets pretty annoying lol. is there a diy anywhere? sorry, didnt have time to search.

 

I believe fsttyms1 used 2, cause 1 isn't long enough.
Either way, they come in pairs.

edit: here's a diy.

Yep, need to drill one out and put the both together.

 

sidebar - how much should o2 sensors cost?

 

What exactly does this do to make the CEL turn off? Er, how does it help the O2 sensor work? I've had the p0420 for a while and already replaced the cat 2 years ago. Was going to look into replacing the O2 sensor if my EGR cleaning doesn't resolve the code, but this sounds a lot cheaper. Or is this fix only for getting a CEL when installing a new high-flow cat?

 

Amazon has OS sensors with longer leads.....you just have to read the product description carefully to find them. Look for the same sensor that has a higher price for no apparent reason and check the product verbiage.

smarty.
