98 Toyota Avalon-check engine light

Can anyone give me some code help please? I have a 1998 Toyotal Avalon XLS 3.0 liter V-6 with 105,000 miles on it.

The check engine light is on. The code provided by the dealership when I had the valve cover gasget replaced is PO 135 B1s1. I think it is the O2 sensor but before I replace it (at a cost of about $124.00) I want to know if I am replacing the correct thing.

Thanks for any help!!

i haven't worked on a toyota, the codes are standardized industry wide though. 'p0135' means b1s1 oxygen sensor heater failure, it could be a sensor or it could be a wire feeding it or it could be the computer, only a properly done test will determine what it is. b1s1 can only mean one place 'bank1' and upstream(before catalytic converter), bank1 is always the same bank of cylinders(3) that have cylinder #1, so, find spark plug #1, follow that side exhaust manifold to the sensor(before cat) , after the cat it b1s2.

hope that helps

also, the check engine light should stay on until the computer retests the system, could take up to three 'trips' each manufacturer determines what a 'trip' consists of and how many times it must pass the test to turn the light off, sometimes unplugging the battery might work, again, depends on the manufacturer

Good info by mike:

It's the sensor in the manifold next to the firewall, usually just failure of the sensor.

yeah, i know, i've replaced a bunch of sensors for this, only once did i have a heater failure code for all four sensors, it was 'only' a fuse that was blown(by a rubbed through harness)

i just didn't want him coming back saying he replaced it and now the dealer said he needs a computer or something like that

Thumbs up

All posters are correct. At the mileage you have, the 02 sensor replacement would make sense.
