In this video I give a demonstration on how I went about troubleshooting a P0155 P0135 heated oxygen sensor, heater circuit diagnosis

Thank you for taking the time to make these videos. Your description of testing O2 heater circuit was very clear.

This is a great video for the home mechanic who may be encountering this problem for the first time and may not be too familiar with using a multimeter and testing electrical components very clearly explained so you can go ahead and diagnose adding more diy knowledge, many thanks from the UK

This is extraordinarily helpful and exactly what I needed to know in helping me understand what the PO0135 code issue is with two of my 6th gen Civics.

Good video Will. Just wanted to point out that when you do a voltage check on the O2 sensor supply volts, you really need a load on it to verify that all the connections starting at B+ would be intact to the sensor. This would also include the relay contact which would be the most likely problem if there was an issue in this circuit. Thanks again!

Even though it's from 2013, I greatly appreciate you posting this video. I have a 96 Astro that both Bank 1 and 2 O2 Sensors that have gone out as well. But it has been sitting along time and getting it running again. Definitely will be using the tips!

Great video man, helped me out for troubleshooting and taking care of my engine check light. Cost me about $50 for the sensor and 1hour of my time. Had I brought it to the shop I probably would've had a bill of $150 or more. Thanks a lot! You got a new subscriber!

Hi Will! No problem as I knew you knew this already and figured you was going for speed as you pointed out with the open heaters.

Good point thanks for mentioning, wish I had more time while performing this repair, I usually load the circuits in question with a test light, “bulb” style not LED if it lights the bulb nice and bright most times all is good, in hind sight I should have demonstrated that, however I had a feeling the heaters were open and went straight for the DVOM, if the resistance was ok then I would have loaded the circuit, in addition to checking the controlled ECM ground at the o2 harness, thanks again

Thank you , yea the pico is a great scope i would like to pick up the automotive kit whenever the budget allows lol needless to say i will be using my old bench top scope for awhile, i have used it on a couple Hyundai's on those i could monitor just about anything i tried, didn't go to deep with them just whatever troubleshooting they needed at the time, keep in mind i have the enhanced AutoEnginuity so that makes all the deference, now if you just pick up the basic generic its very limited

Resistance Test is Not always conclusive, resistance changes when hot can trigger the check engine light.

My sensors are brand new. Would it be the relay then? I replaced them this month and it ran fine. Got in a wreck and got my truck back today. Engine light is on and my scan tool gave me these codes.

Yo Rob,do you have any videos with P0420 diagnose. Yeah that code. Want to find out why keep getting this code on various cars. Just don't wanna install the cheat code adapter without finding out why it throws the code with good fuel trims.

Calling an open circuit "open loop" is not a good idea when working on cars, especially on oxygen sensors, since the term "open loop" or "closed loop" has a completely different meaning. It's only going to confuse people.
@dianefalvey12937 жыл бұрын
how does it have a different meaning in a circuit, a DC circuit mind you, if you have taken physics you will see that Kirchhoff's rules states current in and current out in loops must be equal. A circuit is a loop in Lehman's terms.
@Case_7 жыл бұрын
Yes, a circuit is a loop. It still doesn't change the fact that the terms "open loop" and "closed loop" have a very specific meaning when it comes to engines and would best be avoided to prevent unnecessary confusion. BTW, I'm a certified high voltage electrician by trade. Well, originally. So yeah, you can say I've taken physics.
