Car has about 81k and just recently after filling up got the po141 message read by autozone. reset the light and got it again within a few seconds of starting the car. checked the 15a fuse and it appears fine.

How can I located the sensor and ohm test it?

Thanks

Cory man

The P0141 code is extremely common on the 03-05 Accords. Ive replaced at least a dozen. hth

from reading that seems to be the case. Im guessing your a mechanic? Do I need the bosch oe type 4 wire? which one (what is the location ) am I testing first and how hard is replacing it? I have a jack and rhino ramps

Thanks

yea.. I replaced a few myself when I worked for Honda.

Before you buy anything, do you have your warranty manual? If you do, check to see how long the warranty is on emission parts (like your O2 sensor). If you're lucky, you might be covered for 10 years on those parts. If you don't have that manual, call one of your local honda dealerships and ask for a service writer (hopefully you get a good one) ask about the warranty on emission parts for your accord.

ok so this morning I ohmed the o2 sensor and it read as open no resistance on the meter. I went to honda got a new one and it ohmed fine. installed it, erased code and the code hasnt come back like it did before. we'll see if it happens again.

you shouldnt have a problem with the code coming back since you replaced the sensor. its a very common code. i replace at least 3 a week at work. i work at a honda dealer.

As a former Honda employee, you should know better than anyone that the only emissions parts covered after 3 years or 36,000 miles (or 4 years/48,000 miles for Certified used) on '98+ cars are the cat converter and the PCM - and even those are only covered to 8 years or 80,000 miles.

Now is that for California or 49 state-Federal cars?

And sorry, not all honda techs are up-to-date on the expiration of different warranties. Thats why we all have at least one warranty clerk to help us out.
