p0135:: how serious?

[Peter]

i have code p0135 on my gen1 solara right now. anyone know how serious this code is? should i get it fixed right away?

reason i ask is cuz i wanna do it myself but dont have the tools/space at my apartment in sf. so i wanna wait to go back to socal to do the fix.

ps. i've already driven about 1k miles w/ the check engine light on...

i am going to tell you a secret: try P1035 in yahoo and google, you will find a lot of info about it.

if i remeber correctly, it is the bank2 sensor 2 sensor voltage problem. if you dont feel difference in performance, than it is not serious

rewording my question: will this cause further damage if i put it off? i have googled and yahooed, but all i find are repair threads.

135? thats just the cat converter sensor. I'd say dont worry about it. The only 2 sensors that matter are sensor 1's because those are what actually measure for correct mixture, not really so foe the 135 which is throwing your code.

interestingly, i tried to yahoo it and i found myself wrong. it is bank1 sensor 1 oxygen sensor. and guess what, this is answer for your concern i found on the internet for you.

sweet, thanks for the replies, i knew i could count on my fellow solaraguys to come through for me on this one.

Ironically enough, I got the same problem. Im debating whether to change it out myself ($150) [Sadly im not too mechanically inclined] or take it to a Toyota Dealership ($280). Either way, I am going to buy an OE O2 Sensor. I do notice a slight difference.

Hence my question to all of you..

When I take my foot off the accelerator, it dips to about 900RPM then jumps to 1100RPM. is this normal, is the O2 sensor responsible for it or is the car in some kind of "safe mode"?


Thanks a ton,
