I got a CEL and the dealership told me it was the oxygen sensor on the right bank.
Now, I like to think that I know cars, but when my wife asked me what the O2 sensor was and what it did, I could only give a reasonable approximation of what I thought it did. Can anyone help?
By the way, the $500 I paid for the extended warranty from CarMax just paid off. It was $460 for the repair. I know we all hear about people who buy used cars and think the extended warranty is a ripoff, but with CarMax it was easy to make the claim and close it out. I just owed the dealership the $75 deductable.
Huge fan of the extended warranty.
So far ECP has covered my steering rack and linkage, exhaust manifold including the O2 sensor. Mine wasn't $500 though,
I had Lexus include it ($1500CDN) when I purchased the car
I just took B2S2 out and cleaned it with compressed air then put it back.
It was a little loose when I took it out so probably
that was why CEL was on.
Reseted ECU and no CEL so far
If CEL comes back on, then I found the sensor for $105 on ebay (Bosch, new)
My car is a 2001 IS300
Here some pics:
"Y" Pipe sensor:
I had to take the passenger seat out to unplug the sensor.
I just put on a megan racing down pipe, and I must say the the O2 sensor was bitch to get off! I had to heat it up with a torch, and now it is basically stripped, so I could not tighten that much when I put it back on.
Anyway
Apparently it was fine until just an hour ago I was driving and the CEL and flashing traction off light came on.
So I have a question, do you think I need to replace my O2 sensor, or should I just bring it somewhere and get it tightened more, and see what happens? And what will they say if I bring it to the dealership? Will it be covered by the warranty? Or will they say tough shit?
I can assure you it WILL NOT be covered under warranty. You messed it up and as soon as they see the aftermarket part on there then they will stop work and tell you sorry.
I just replaced mine myself.... I got the OEM part from lex for 176.00 well worth the xtra 66.00 so i didnt have to cut/match up any wires... it was just plug and play... took me all of 30 min to do...the CEL for an O2 sensor shouldnt have anything to do with your trac button... if trac wont work you have another issue.... You probably ruined it with the torch.... I'd get a new one throw some anti-seize on there and plop that bitch in and be done with it..
And I would like to add that I think it is stupid that I have to pay for a new o2 sensor just because I put on a new downpipe. I don't even understand what causes the problem, why does it make the CEL go off?
The down pipe probably isnt your problem.... It was heating it up with a torch to get it off initially..... when you crank on those things they break... sensitive.... make sure you put anti-seize on there when you throw the new one on and you wont have an issue....
