Come along in this video as I see what is plaguing this 2002 Honda Civic Coupe' and find out what is making the check engine light come on with a code P0131. Once we see what the problem is we dig a little deeper and have some fun with the scope comparing "scan data" vs "real time data" with the scope and scan tool.

    Can a bad 02 Sensor cause a car to shut off at Idle? I have a 2005 Civic.

    Thanks for being honest about your diagnostic tools. You Just saved me a boat load of $.

  10. Avataaar/Circle Created with python_avatars ZeldaNumber17 says:

    Thanks Eric. This helped me diagnose the upstream o2 on my escort zx2. It was so lazy after the car was warm, almost same exact problem. Would dip down to .1v very very intermittently causing a buck when the engine speed was between 2300-2600rpm. Restarting the car would fix the problem for a bit but it would act up again. It was driving me nuts forever because it never threw a code….

  11. Avataaar/Circle Created with python_avatars James Wood says:

    Ground wire is pretty much gone

  12. Avataaar/Circle Created with python_avatars Shane Harrison says:

    Cool I enjoied the diag

  13. Avataaar/Circle Created with python_avatars TinkeringTom says:

    My O2 sensor one has a flat line and a voltage of 2.1 is this normal or something very wrong?

  14. Avataaar/Circle Created with python_avatars Nicolas Xu says:

    what's the issue? I still don't understand if you have found the issue yet.

  15. Avataaar/Circle Created with python_avatars scientist100 says:

    I can upgrade this Verus to SSD, if you still have it, I can explain to you how to do it or look it up online. My Verus Pro is running great after I upgraded to SSD.

    2002 hondo accord p0135 code, checked heater circuit good but no 5 volt from fro ecu ? broken wire ?

  17. Avataaar/Circle Created with python_avatars Bryan Krall says:

    That’s one of the best cars ever made.

    Brilliant video to help a even a novice who's keen to try learn a go thankyou 😊

    start another channel railfan that powerful shit!!!

    P0132 Circuit HIGH VOLTAGE?????? THANKS

  22. Avataaar/Circle Created with python_avatars Tech NO City says:

    On that snapon tool. I could make a norton ghost backup so if you have issues you can restore the image or just clone the hard drive. Hit me up id do it for cheep if you cant.

  23. Avataaar/Circle Created with python_avatars Detroit iron rescue says:

    Here is a humdinger for you
    I have a 94 Honda Accord standard 16 valve I have a code 21 I do not have a VTEC. So what's the problem?

  24. Avataaar/Circle Created with python_avatars steubens7 says:

    seen a few videos suggesting cleaning the oxygen sensor for some related codes? can you even do that? one method uses a torch to blast off the soot, something you can do when you bench test it. another soaks the end in gasoline over night

  25. Avataaar/Circle Created with python_avatars Ning3n says:

    Free ASE training. (Except for that windows 8 crap-on tool)

  26. Avataaar/Circle Created with python_avatars Efren Luna says:

    I got a problem the Car crank and no star

  27. Avataaar/Circle Created with python_avatars Chris says:

    The error with the Varus you're getting is an OutOfMemoryException. This is mostly harmless in terms of the function of the device. Its almost never an indication of a hardware problem in something embedded like this and no need to send it back to snapon. Generally its a software issue due to attempting to do too much at the same time on the device. Either you're overloading it or the software that runs on it was done poorly. Anything on the scope that involves history like taking traces or having lots of browser tabs open will eat into your maximum working memory. Closing down programs or restarting the device should help free things up.

  28. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    Great comparison. I'm surprised at the comparison with the old sensor. Apparantly the PCM is putting out a signal, but checkout the 02, not good! Great Video!

  29. Avataaar/Circle Created with python_avatars vpsaline says:

    Do busted O2 sensors cause bad fuel mileage? What can be the consequences if left un checked?

  30. Avataaar/Circle Created with python_avatars Duncan Mac says:

    I think that Snap-On should buy that tool back from you for the price you paid for it including all the repairs and then go find one that works from a different company. I'd be quite upset with that them if I were going through what you're going through. It's just not right. You shouldn't have to pay for repairs on a faulty piece of tech.. I'm angry just thing about. I've got to give you credit for being so level headed about it.

    Thanks for another fine video, I really appreciate the effort you put out put them together.

  31. Avataaar/Circle Created with python_avatars Robby Jones says:

    Scan tools should have the thumbwheel like a Snap-on scanner to turn up the idle.

  32. Avataaar/Circle Created with python_avatars MY KEYS AUTOMOTIVE says:

    He trys to sound like eric the car guy,anyways good video thank you!

  33. Avataaar/Circle Created with python_avatars Jay Cuff says:

    WHAT MODEL AUTEL R U USING

  34. Avataaar/Circle Created with python_avatars Terry Jenkins says:

    What if you had a heater code and put 2 new o2s in and still have heater code?

  35. Avataaar/Circle Created with python_avatars Juanluis Marmolejo says:

    excellent video . always supporting us with your work greetings from Mexico, hopefully one day you can put subtitles in Spanish, so you can understand more the videos greetings 👍

  36. Avataaar/Circle Created with python_avatars Simon flores says:

    where did you connect the leads to check the heaters wires

  37. Avataaar/Circle Created with python_avatars Kingofspades509 says:

    What’s the PN for that scanner?

    How can you tell if the CAT is no good anymore?

  40. Avataaar/Circle Created with python_avatars Brendo says:

    Great stuff eric o as we say in ireland your shit hot bud

  41. Avataaar/Circle Created with python_avatars Richard 1 says:

    When you say the STFT is pegged out at a positive number, does that mean the ECM is adding fuel because the O2 is dead or stuck lean? Thank you. I enjoy your videos and have learned alot from you.

  42. Avataaar/Circle Created with python_avatars Fixer 1 says:

    I know this is a year old video but I couldn't help myself. I noticed the upper rad hose on that Civic looks bad. may be camera is fooling me.
