    Thank you for explaining that. You just saved me a lot of money. Initially I was going to replace all 4 sensors in my ford truck but I did not realize that the dow stream sensors were specifically for the catalytic Converter. My truck recently started shutting off in the middle of traffic, so more than likely just my upstreams need to be replaced.

    Watched the video and i have a question does the OS is counting the oxygen in the exhaust gas all the time or only in some range of RPM....for example only on idle.... and no under load ex at 2000rpm cruising...TIA

    I just replaced both 02 sensors in my Toyota Tacoma yesterday. I had the upstream sensor in for 14 years and the downstream in for 11 years. Man, what a difference in my engines performance. Everything runs so much more smoothly like i just got a major tune up. 485 dollars, but money well spent.

      I thought not can you help I have a 2016 Nissan QQ 1.6 Petrol. I replaced the bank 1 sensor 2 12 month ago this sensor failed again code P0138 H02S2 and P0037 I have a reading of 1.79v reading on the diagnostics H02S2 and it’s running rich. Before spending money on another sensor can you help with what’s going on like I said the sensor was only replaced a year ago could this be a dirty cat? Also do you have any recommendations on cleaning the cat without having to remove it I have been reading people have been putting Lacquer Thinner in the tank ??? thanks for your reply I look forward to hearing from you cheers

    The o2 sensor does not sense outside oxygen… just what’s inside the exhaust.

  • @Alwaysbusy300
    @Alwaysbusy300 2 ปีที่แล้ว +2

    Thanks. I understand the oxigen s it's there just. Manipulate the fuel and make the car rum on the computer mpg especified from the Manipulate car market, that say if the car can give 50miles per gallon the ecm will make more fuel into the exhaust then all the. Energy waste on the donw pipe its burn at catalytic converter try to give less contaminated air out , or just say car its eating the fuel accordingly to the monopoly and that it's how its done into the computer control, and the cat. It's there just to burn the remaining fuel, and u don't smell the raw fuel coming out of the exhaust otherwise u catch back ad more oxigen and re-burn entirely end use the energy that it's waste at cat. By the. Way cat I control automakers treason

    The car failed the too much CO emissions test. and blue fumes from the exhaust... I know that the PCV valve could be the cause or the EGR valve could be closed, maybe I should take a look there, I have also had problems with reading. But no light came on. my code is P0400 Recirculation malfunction flow another the P1132 lack of H02s11 switches. sensor indicates rich see P2196

    My boyfriends car started having error codes ( p0300, p2626, p0132, p0130, p0030, p0302, p0441, p0304)
    Which I’ve ruled out was the 02 sensor or ECM being bad. He’s literally on the way to his next command (military) and his car broke down at midnight.
    It sounded like the engine was misfiring and shaking, would go above 40 when driven to the closest but closed mechanic shop.
    I don’t think it can be anything else but those 2 things. Hopefully it didn’t damage the engine.
    It had a high meaning, not enough oxygen. And it’s an error before the catalytic converter. Or an error on the ECM and just fucking the engine up…. Huh….
