Guys,
I am hoping at least one of you can guide me.
I have a check engine light on with a code of P1135.:sosad:. The car is Camry 2001-4 cyl.
The OBD reads " Factory installed air fuel ratio malfunction"
Any one knows what this exactly could be?
I understand these codes are not an exact science but guesses are fine.
Also let me know any auto repair service chain that's reliable.

Thanks for the help folks.

Chronoti,
its not P0135, IT IS P1135.
It may be a O2 sensor, but the code is P1135. Its regarding air/fuel ratio so it could be anywhere from the mass flow sensor to an EFO sensor

Please help

(Make sure you find out if you have either federal of california emissions) because at times they use different parts. Also the california emissions camry part are more expensive than the federal emission.):sosad:

Might DIY, Rockauto has a California O2 sensor for under $100. Check Autozone, etc for local prices. You can downloead the service manual at:

You're right. It's pretty easy to change the o2 sensor that is before the cat. I'd recommend looking around for the cheapest price o2 sensor for cali emissions and do it yourself.
You can use the money you would've spent on labor for some ie.. good food, gas and a oil changehyeah:

Just take a look under the hood and you'll realize just how easy it's going to be.:whatwhat:
