    Thanks, man. New sub. Definitely earned my business! 🤙This was a very educational video. Extremely helpful! Not only did you explain the code, but you actually explained the possible issues that created the code to go off to begin with and pinpoint where these issues are arising from!
    Unexperience individuals would have probably just gotten the sensor replaced without thinking what caused the issue to begin with! 🙌

    I have P2196 fault code on my Skoda Octavia 1.4 TSI 140hp, when I remove this code from ECU, every 5 to 6 days comes back.
    I replaced O2 sensor before catalyst, all spark plugs and one induction coil on third cylinder because I had a missfire fault code on third cylinder.
    I don't have any problem with power on car, no problem with fuel consumption( I have average 5 liter on 100km).
    If you know why I have every 5-6 days this fault code.
    Maybe I must to change all of inductive coils.

      Is the misfire fixed? If not, I would check the injector on cylinder #3 that has the misfire.

      Now, I don't have any problem with missfire.

      Correction factor on all cylinder is around 1.00.

      When codes randomly come back with a delay, it can be hard to pinpoint the cause. If there are no other codes, I would examine the O2 sensor wiring for any bad connections.

      @@HVAC_Mechanic I can try to clean connector on O2 sensor, when I replaced old O2 sensor I am just put the new without cleaning connector.
      Maybe I must to do adaptation on new O2 sensor?

    So heres my issue i have a 08 ford focus so i first got a p2196 for 02 sensor bank 1 sensor one biased/ sruck rich . So i replaced the sensor i also had a leaking valve cover gasket so i replaced it and spark plugs wich looked sort of a dusty light color. the code went away but i still have the poor engine performance. My syntoms are when i try to start my car it will either be a rough start no start or it will start right up and when it does start the rpm's dip then fluncuate then settles and finally idles but if i put it in drive the rpm's dip again and it seems to idle rough if i try to drive the car i have poor acceleration, low power, jerking , hesitation,
    And when im at a stop light it may or may not stall and when it does i smell gas and i get the p2196 code and check engine light but when i start it back up the check engine light is gone but not the bad performance . I cleaned the maf sensor also but seen no change any advise is appreciated

      Anything I say is a guess, but a dirty throttle body is common with those issues. I would clean up the throttle body with throttle body cleaner and see if it improves.

    Oh mine runs rich. I can smell it. No cats. I replaced bank 1 sensor 1. Purge valve no vacuum when running. Spark plugs smell like fuel. (I changed them all, killed me lol). Idles bad intermittently. It has a cold air k&n air intake. I bought truck recently. Mistake maybe. 2009 F150 4.6 3v engine. Starts really great so no problem there. I cleaned maf sensor. It looked clean before I cleaned it though.

      @@MrTLsnowyes. The wiring to the 02 sensors(actually heater sensors) were plugged in wrong. I had my torque converter changed and the mechanic had accidentally plugged bank 1 plug wire into bank 2 sensor1, and bank 1 plug wore into bank 2 sensor 1. The wires were crossed over the transmission. A different mechanic figured it out and lowered my transmission and fixed it. Costed me 100 bucks and that was it.
