    I have a 1st Generation (1995-1999) Toyota Avalon with a P1135 error also. I change the Denso Air Fuel Sensor P/N: 234-9007 and it solve the problem and the check engine light went away. I change it from the top instead of going under the car it was really easy. Hope this help like other have help me.

How many parts have the P1135 diagnostic code on a 2003Toyota Rav 4? I have replaced the air/fuel sensor and the code P1135 comes back on. I'm being told now that it's 2 sensors in the a/c


The air/fuel sensor and the a/c are two different entities. P1135 is the bank1 sensor 1 air fuel heater circuit code. If you have a four cylinder this sensor would be before the catalytic converter. Since this is a heater circuit issue I would check fuss to wake sure the heater fuse, if one is present, is not blown. Also what brand of sensor did you install? Did you clear the code with a scan tool after you installed the new part.

2002 toyota le 29,780 Miles check light on during driving code p1135


Code p1135 is a code for an Air/Fuel sensor (oxygen sensor). Bank 1 sensor 1. IT comes up when their is a problem with air/fuel mixture in the engine. It would be anything from a blocked air cleaner, faulty or fouled spark plugs to a blocked exhaust pipe/catalytic convertor. I would get these checked out, and if they are all fine the sensor its self or sensor circuit may have failed, requireing replacement. With your low miles, hopefully this maybe covered under warranty if it is the sensor.

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.
