What are these strange readings?! Is this sensor broken?!? You said it yourself the values should go from 0.1 to 0.9V, which are 100 to 900mA, and we see -12 to +6mA ?!?

I'm trying to trouble shoot my tacoma 2000 and was wondering what happens to my truck if the black and gray doesn't work(which is what i'm reading with my multimeter)? Right now it's have a rough idle but runs fine when driving. But since it's an old truck, i'm leaning to an air leak that I cannot find. I'm asking because people always have trouble shooting videos on detecting bad sensors, but not the impact of a dead sensor on ECU. Since it's dead, how does the ECU compensate for it since there is no signal going to it from the 02 sensors? Does it run tell the computer to run lean?

@BjornV78 3 жыл бұрын

To drive the Oxygen sensor to his maximum voltage, you can mount the sensor in a piece of metal tube, and pull this tube it vacuum. This only works offcourse if you have a electrical heated oxygen sensor. The voltage is created by the internal capsule which contains pure oxygen on the inside, and the less oxygen on the outside of this capsule, the more voltage difference is created by the in and outside of this capsule.

@@619guy202 you are correct. The cheap ones, about $15 to $18, are often the single wire none heated wide band sensors. The expensive A/F guage and sensor kits are often a 4 wire heated narrow band sensor that can give far more accurate readings. While the wide band is literaly that. They flucate largely and an average reading is used. A verry budget model guage you will see this fast flucation while cruusing as the A/F is rapidly adjusted continously. A mid range model will have a buffer circut to average out the reading, the ecm still has to adjust the A/F rapidly to account for the average reading of the single wire O2 sensors. The narrow band sensors allow the ecm to more accurately adjust the A/F and a steady value will be observed. As it provides a more accurate reading in the first place. As the old saying goes garbage in garbage out. All though depending on your purpose a mid range or budget model can suit your purpose at a lower initial and life time maintance costs. Performance needs would all ways fall towards the more expensive and more accurate models. As the high end narrow band sensors can cost several hundred US dollars.

fyi O2 sensors DO NOT sense oxygen at all. It senses exhaust heat only, that generates a low voltage that the ecm interprets if the current ratio is correct or not, hints open loop learning mode. To which adjustments can be made to achieve the correct ratio. A bad O2 or MAF sensor will cause your car into closed loop with factory set fuel values to prevent engine damage but will result in slightly to bad fuel mileage.

Best off to clean all the sensors in a vehicle and test them all off the vehicle because if you replace just one it will not have carbon build up and give different readings that will trip a code so best to clean them all so if you replace one sensor the others will be clean and operate in the same range .. just like fuel injectors if you replace just one and rest are dirty and gummed up the engine is going to run poorly and possibly out of balance. clean them all replace the bad one with a new oem one or cheaper yet get one or 2 from a salvage yard really cheap and clean them and have a spare and possibly less then $20 versus $100 plus for an oem injector.. news flash cheap injectors from e bay are made in china garbage and part store one not much better.
