Thank you for sharing.
Thank you so much 🙏
Had codes 1135 and 1155 changed both the o2s and light went off for 2 days now same codes came back. Now gotta look deeper
It’s not an O2 sensor. It’s an AIR Fuel Ratio sensor. Much more costly and works different than and o2
You’re correct but where is the “Air fuel sensor heater circuit”. I got the Air fuel sensor heater circuit response malfunction message. What should I do?
@@jackjones9460 Its not a separate unit. Inside the A/F sensor is the heater unit. I'm also going crazy with the P0125 and P1135 errors. I have replaced the AF sensor, Coolant sensor and the thermostat with Original TOYOTA parts but the errors are still there.

@@ksd9756any luck yet? Im having the exact same thing
@@ksd9756 Did you ever resolve this? My own Avalon is throwing a P1135, P1133, and P0125 codes and I'm wondering if it's fixable by myself or if I'm gonna need to hire a mechanic to help. I'm broke af so I'm hoping it's something I can fix myself.
Hey I got 01 Toyota Tacoma V6 motor 3.4. Got the p1135. I replace the oxygen sensor up stream. But still same code. Can plz help me to find the fuse or relay. Plz may be that is the problem. Plz ye video wasn't clear to me about the fuse part
There is a fuse in the engine bay fuse box for the 02 sensors labeled AF Heater. I believe the 2001 Tacoma also has a relay. I would examine the wiring for any opens or shorts. The heater element in the sensor can also be tested using a meter. Even new sensors can be bad sometimes. Here is a video I made testing the heater element of an 02 sensor. th-cam.com/video/CviauEqXTLk/w-d-xo.html
Do you have the exact part number of the sensor?
I have a p1135 and a p1130
That what I have also. Did you get yours resolved? What did you replace?
I also have p0100 and p0101 which relate to MAF sensor.
