Received 0141 code which is rear O2 sensor. Under the car, on the passenger side in the middle of the catalytic converter I saw a sensor. I couldn't see any other one. Is that the right one? I'm having a real hard time loosening the sensor. I have sensor tool and socket wrench & I used PB Blaster to no avail. I am afraid I might snap something or break catalytic converter if I try push too hard..Any suggestions?? I don't have much room for leverage under the car..

 

raise the car higher and use jack stands for your safety. use i believe a 22mm wrench. spray some wd40 beforehand and it should loosen.

 

actually most of them are 7/8" wrenches, but OP said he had the right socket to do it though



but anyways OP, where are you located (trying to see how rusted the sensor might be rusted in there)

 

I drive in NYC and Northern NJ. Bolt isn't moving..Need to buy a jack that goes higher..Guess a 17" breakbar would help also..

 

good luck getting that sucker out


it might be worth it to let a shop replace it (a new bung might actually have to be welded on...)

 

Drive the car for a while so that the exhaust gets nice and warm, it may aid in getting it out. Apply a lot of force is all you can do.

 

Hi!
How many 02 sensors are on a 00 Acura TL?

 

two, one front and one rear


but i see you are from Poland, are you here in the USA or Canada though....

 

Yes. I'm from Poland. I've never been in the USA/Canada. Unfortunately...

 

Where is located the bank 1 oxygen sensor? Nearer engine? Part number this 02 sensor 36531-P8E-A11 or 36532-P8C-L21?

 

only issue with being over seas, the car might have been built to a different spec then the ones here

do you know if it is a USA ( or Canada, which is slightly different though) or a Japan Spec car?
also if a USA spec one, is it a California emissions car, or a 50 state emissions car


that that could potentially make a difference in needed part numbers




but the A11 would be the front o2 sensor, while the L21 is the rear one, both are bank 1 btw, but sensor 1 and sensor 2, to be more specific





edit: if you would like you can also PM your VIN, and i can doable check for you especially if it is a USA spec car, (is the speedo primary in MPH, along with the HVAC controls in Fahrenheit?)

 

hey can you clear your PM box Natasha

 

Hey, try now send me PM.

 

sent...

 

I replaced my upstream o2 sensor and its looks like I have lost about 5 miles per gallon on my gas mileage. I was thinking that since I haven't replaced the downstream sensor maybe that is the reason. The downstream sensor isn't bad yet but maybe mixing a new one with a old might be the issue.
