SOURCE: Check engine light came on.

P1135 means that your O2 sensor has gone bad. The O2 sensor on the Toyota's are called Air fuel sensor's. If you have a 4 cylinder engine, the O2 is on the exhaust down pipe before the catalytic converter, and if it's a V6 it the O2 sensor on the fire wall side along the down pipe from the exhaust manifold. (sensor 1, bank 1) Good luck and keep me posted, check the wire harness. The wire harness could have corroded or burnt from the exhaust, but most likely it's going to be a bad O2. Keep me posted ,be glad to help

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

I have a code p1130 p1135 what does this code need to have repaired


they refer to the air/fuel sensor circuit and air/fuel heater circuit , the 0125 code refers to engine not getting to operating temperature , so that is why the other two codes are read , check coolant level, if ok check that the thermostat is opening , if it is then you may have an air lock in the coolant system so bleed the system , whilst bleeding get someone to switch the heater temp switch to hot and back to cold a few times as thats where an air lock could easily get trapped

CHECK ENGINE LIGHT JUST CAME ON. SO, HOW CAN I TELL IF MY A/F SENSOR IS BAD ON MY 2001 TOYOTA TACOMA? IT IS PULLING UP CODE P1135 BUT, IS THERE A WAY TO CHECK THE SENSOR ITSELF TO SEE IF IT IS BAD? THAT'S...


the code refers to the air/fuel sensor--heater circuit response, bank 1 sensor 1
That indicates that the HO2S( heated oxygen sensor in the exhaust manifold bank 1) is faulty --possible wiring problem or sensor failure

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.
