Question about 2003 Toyota RAV4

1 Answer

P1135 code on 2003 Rav4 - would like to do this repair myself. I had a previous fault for a bad O2 sensor that had not been fixed yet. I understand this is an Air Fuel sensor (different than the O2?)

I have p1135 code problem How can I fix it and where it is located if i have to change it?


It is a faulty o2 sensor possibly. there are 4 on your car. This code is for the one on the ride side facing the engine on the exhaust. Get you a new sensor and some pb blaster, oh and a o2 sensor socket. Have fun.

O2 malfunction P1135. Please what do i need to buy to replace ? Can I do this myself or will have to let an expert do it. i would be very grateful if you could tell me what EAXACTLY that I need to buy...


The P1135 code on your Toyota is Air fuel ratio sensor - heater circuit malfunction. Basically the problem there will be with the air/fuel ratio sensor (on other vehicles it is refered to as an O2 oxygen sensor), or the wiring/connectors leading to it. It could also be a problem with a fuse or relay on the heater circuit. Again, not a real difficult problem to solve.

just fixing the P1135 code will not cause the check engine light to stay off because there are other unrelated codes. If the code P1135 was causing the other problems then perhaps fixing that code would fix the others, but that's not the case here. The reality is you'll need to have all the problem areas looked at (IAT sensor, MAF sensor, Air/fuel ratio sensor) and repaired in order for your engine light to stay off. Normally if there are codes stored a vehicle cannot pass inspection. I would get a second opinion from another local mechanic as what you've been told may not be 100% correct.

Good luck.

Engine light comes on with code p1135 control fuel air metering. how do i fix this?


P1135: A/F Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

Your first O2 sensor is not getting heated either because the wiring to the sensor is bad or the heater inside the sensor is bad. If you have a four cylinder this would be the only O2 sensor you have before the catalyst. I would just replace the sensor, clear the code, and see if it comes back.

Getting code p1135 and p1155 on toyota rav4 2002


Here's what the codes mean:
P1135 Air/Fuel Sensor Heater Circuit Response (Bank 1 Sensor 1)
P1155 Air/Fuel Sensor Heater Circuit. (Bank 1 Sensor 2

This is mainly related to the oxygen sensors. It maybe the sensors themselves or an open wire going to te sensors. They are mainly located on the exhaust pipe. One before and on after the catalytic converter.
