Oxygen sensors (Air fuel ratio sensors) are a common problem on many vehicles. A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor.

Some background info on difference of Oxygen Sensors and Air/Fuel Ratio Sensors. What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor. It can detect a wider range of air/fuel ratios than the basic O2 sensor. Also, the AFR Sensor has a little bit more circuity to enable it to detect more minute variations in the exhaust system air content (more sensitive than the O2 sensor). Therefore, it is able to make better adjustments through the ECM to add or subtract fuel to produce a better mix of air/fuel to maximize efficiency and minimize emissions.

O man I wish you worked on this car more. I just bought one with bad head gasket and bad clutch. I’m struggling. The axles don’t come off so I gave up on that for now and I’m making it up as I go taking apart the top of the engine. I reached the point to take this sensor out but I don’t have this socket and I’m stuck! 😢
chris hi do you check the sensor with the engine off or running ?
Hi, my car kia stonic 2018 1.6 crdi had new dpf,turbo,egr,intake manifold and o2 sensors, and it's still running rich , showing 0.9v at idle and when cruising at constant speed stays at 0.4-0.5v, when giving it throttle it goes down to 0.1-0.2 , when releasing the gas pedal goes as high as 1.4v , running i guess as it regenerates the dpf every 130 miles and has a thin layer of soot inside exhaust tailpipe. Any suggestion what could be wrong with it, kia don't seem to know what's wrong with it .
Thank you
Not throwing any codes.
Chris how do you find the cooloant temp sensor ….i got a mitsubishi grandis …the fan dosent come in so it overheats idles rough and rpm fluctuates could that be the problem?
thanks for your video can u give me your number to contact you on whatsapp?
I cant seem to take it off. It is really in there. Any advice anyone?
How to check a air temperature sensor
Thank you for your great videos! Quick question…after changing the sensor what would you do if the engine light came back on and the same code p2197 came back on 😮💨🤦
8 years later I’m using this video and how to clean mag sensor haha
you make everything look easy! i was changing one on a saturn sc2 an it was so dang seized up an i went out everyday for a week an sprayed it with pb blaster i had to end up getting a big ole cheetapipe an break it loose
I literally lookes for "chrisfix o2 sensor" and i didnt remember any video on this, but here it is and now my car runs smooth again
I had the same issue with oxygen sensor bank 1. However it did not gave me check engine light which is really weird. When we scanned it, the same code appeared though.
One of the best mechanics on youtube ❤ very informative
It’s Not only for Toyota and Lexus every car need it to be cleaned
