donkene: Tell them to change air flowmeter and brainbox

myke20: ...I scanned it and it was shown that d culprit was d oxygen sensor. Since den no mechanic has been able to diagnose whether it is the oxygen sensor dat is bad or it is an electrical. Even to know where the bank 1 sensor 1e is na problem for dem. Now d car consumes fuel like mad...the car is toyota camry 2003 big daddy.

myke20: Thanks all d code is P1135 and its actually air fuel sensor. But they said is d same fin as oxygen sensor. I really dunno o.is the bank 1 sensor one d plug like fin on the exhaust manifold facing the radiator or where e dey sefpls help a broda out.

jodeci: Do you just accept whatever you are told? how can O₂ sensor be the same as air fuel sensor.you make it difficult for anyone to be of help.

myke20: @ cretin one rewire siad dat d sensor might be good and dat it is not transmitting current or sumfin like dat sha. So dats y I'm confused

Ikenna351:


How many wires does your o2 sensor have?

If its 4, that means the sensor has heater. And to have the heater, it will need 12+ from relay to power the heater. You will need to find out if you are getting 12+ on any of the wires to the sensor.

You will also need to find out which of the wires is from ECU to the sensor (signal wire). o2 sensor signal wire should have about 0.65 volts, when tested, without connecting it to the sensor. if it doesn't have its own volts values, then the ECU is not signaling to the o2 sensor or it could be the wire has broken and not connected to the ECU anymore.









Bros I tire o. Pls where r u. D sensor has 4 wires sha but d millivolt fin go hard o. Abeg help me do am na. Where r u sef. But pls u can give me more info shaYou can as well test the oxygen sensor to know if it still produces factory volts values, to really determine if actually the sensor has failed or not.

All these test above will have to be done with DMM (Digital MultiMeter), the one with milivolts feature, that cost more than the others. Maybe 2k or so.

Do you think you can carry out the test by yourself, I

f i guide you?

But i still need to know how many wires the o2 sensor in your car have.

Siena:

Hey, don't pick on the guy. They ARE one and the same. Lambda Sond, O₂ Sensor, Lambda Probe, Oxygen sensor. What you pull with your scanner depends on what scanner you use, and what ECM you're reading.

Or what do you think the difference is between what you've posted - air / fuel sensor, and O₂ sensor? O₂ = Oxygen. Air = 21% Oxygen.

myke20: @ cretin thankss. So lemme just change d sensor na abi since even if its d heater dat is bad I will still change d sensor
