How to test pre-cat O2 sensor - correct values - Toyota Aygo, Yaris, C1, 107 - P0134, P0135 lambda

[@crpth1]

Although it makes sense testing the O2 sensor directly. In case of any doubts about it's good functioning. Remain the fact that you have "torque" running well. So, simply go to the test option and read both O2 sensors. Their data is readily available. No need to pull the wires, etc. ;-)

What vales in torque for both sensors

For Yaris the resistance in heater wire is 1.3 to 2.8 ohm . Not 13ohm

Ive got around 7ohms on my both oxygen sensor. Is it bad and need to be replace?

[@michalbinar2666]

Hi, I'm fighting this code P0134. Voltage on the signal and ground is 0,0V. Is it possible for the engine unit to be damaged? The wires are fine.

Did you managed to find the problem? Having the same problem :/

[@michalbinar2666]

@@NerSkirtumo Hi Yes. the problem was in the wiring. unfortunately it's been too long and I don't remember which one it was.

What should I do if the voltage on the white wires from the engine side connector is 0V??

Where can i buy the code checker?

Help i did this and now my car wont start what did i mess up

[@kocakdjinisov7777]

is 0,93-095 ohm to low?

[@TheBlackbd]

I have error code P0140 and P0141. What do they mean? Is there any fix or do I have to replace the sensor?

Flux Incapacitator Toyota vitz and aygo same o2 sensor..??

[@mm-pf8jk]

I have done it same as you, but the erros come back. Sometimes after a day, sometime i keep reading faults

[@mm-pf8jk]

Is cleaning te 02 sensor a must for my problem?

[@MKasap-te8vm]

How did you resolved the problem?

Thanks

Sorry 11ohms with motor and o2sensor cold i suppose.

you just coppied the procedure
