    Thank you for being so informative without any background music. Super helpful video.

    Great video. Just wanted to add a little trick I came up with. When replacing the front sensor, I tie a string to the sensor wire and dangle it down from above, through the engine compartment (be sure to leave enough slack, of course). This helps keep the wire from getting all twisted and flopping around. And when you're done tightening the sensor, the plug end of the wire is easily reachable from above, and you just plug it in.
    And as others have mentioned, RENT THE TOOL FOR THIS! You will be glad you did. Most parts stores lend them free.

      Nothing insane about the wrench. I had an S10 pickup i had to use a pipe wrench and a long cheater bar to get it out of the exhaust. Using only a wrench means you are not in the rust belt

    Thanks for the video. I was got a code saying that my catalytic converter was bad. After plenty of research and seeing how much a catalytic converter was, I decided to chance it and change both sensors on my 2013 Crosstrek. It’s been several months and I’ve had no issues.

    Appreciate you showing an O2 sensor socket and installing to torque spec. The sensor housing isn't as robust as people might imagine. My 09 legacy H6 sits parked in the garage until I get both left bank sensors. I thought it was good preventative maintenance doing the rubber outlet/inlet for the 5eat at 100k. I had to drop a new radiator and thought it would be smart doing all 6 ATF hoses. Unfortunately, I don't have much for tools and ATF fluid soaked both sensors. I found out how external contamination works. It ran about 5 minutes until the whole left bank was misfiring and the engine shaking like it was death. Another good reason to not neglect the inner CV boots when they start to tear. H6 is double the fun. The charge port for the transmission sits right next to the cat also. Just a reminder to don't be sloppy or try to get by with an improper tool.

    • @kennywowie

      I hope you used the proper cleaning spray. The wrong one could damage the MAF. If it's the o2 sensor going bad be sure to replace it very, very soon before other damage is done. Not an expert but this is what everyone says and warns about.

    Hello @MrSubaru1387, thank you for this and other very informative videos. As the owner of an aging subaru outback (2007), I have come to learn a lot from your content and expertise.
    As mentioned, I own a subaru outback 2007 H4. I have been experiencing intermittent check engine light on this car for about 3 months now, and the code is P2096. I say intermittent cause over this time, the check engine light has gone off on its own, and then came back on after a few days. One more thing to note is that it first came on a few days after I replaced the engine air filter for the first time since I put on 150k miles on this car - I know, it was long overdue.
    * I have since gone back in and checked that the box that houses the filter is sealed shut since that could have caused the fault, but i did not find any issue with that.
    * The next step for me is to replace the downstream oxygen sensor, but I hesitate to do that since I think if it was bad in the first place, the check engine light would not show the intermittent behavior, but will stay on. Even if i cleared the codes, it should come back on consistently in a reasonably short time of driving. But I am no expert, this is only my guess.
    What do you advise at this time? Any pointers will be very appreciated, thanks in advance!

      You may be right.. Mine's at 358k but hasn't had a O2 sensor replaced since I bought it at 105K. Stopped running recently so it's time to replace them. So, it seems they lasted at least 250K if not the full 358K.

I don't know which one is the problem, the 02 sensor or the catalytic converter? I tried taking the negative from the battery and used obd2 sensor to clear the code, it cleared the check engine and cruise lights but the same problem would reoccur after driving for 30 minutes or so. May I please ask for your or anyone's assistance and suggestions what to do. Thank you very much

I haven't clean the EGR because I'm unsure which one is it. Can you make a video on your brother's Outback on where to find it and clean it. I'd appreciate it.

    @themaestro5338 5 років тому +1

    ok so I'm going to to confess that after a probably a year of putting it off I am must now getting around to trying to see why our Forester is throwing these codes. I've got the Check Engine light along with flashing cruise control and a steady traction control light on. I decided to go get the codes run at a local store again today (I hope their scanner was good) and today and same as before it showed P2096, P0113 and P0102. The MAF is fine, if it wasn't, then when you unplug it the car would simply keep running. Nevertheless I cleaned it with some MAF cleaner anyway. I also checked the air filter. It's fine. The fuel mileage has seemed ok. It's my daughter's car. She doesn't drive a lot, but we'd notice I think if it was really eating up the gas. I'm going to officiallly do a MPG check on it next fill up since I set the trip odometer on it last fill up. (Dad always buys the gas). I've had the shop look at it. They just ran the codes and were going to to charge me to do the work I can do, which is to replace the downstream sensor.
    The car is driving fine. There's no hesitation at all. I just don't think there's anything at all wrong, but then again, I'm not a mechanic so I'm asking for help here. If the downstream O2 sensor is bad, will you possibly not notice it? I don't know what else to troubleshoot before I replace it.

    • @roboticunclephil
      @roboticunclephil 3 роки тому

      if this is an early Forester you wouldn't notice the downstream o2 sensor being bad at all. It exists for emissions purposes, basically so that it can throw a CEL if the cat goes bad

    Thanks for making this video it is super helpful being able to see what you are doing and which sensors you are swapping out. I'm currently in the process of replacing the O2 sensors on my 2005 Legacy 2.5i. I started by ordering just the upstream sensor because that is the one throwing the error code, but after getting under the car it looks like my sensors are currently installed wrong by the previous owner?? The connector ends match the opposite of what you have in your video. I just ordered the downstream sensor now too, and will just swap them out at the same time and hopefully I plug them into the correct connectors.

    Is it imperative to use a o2 sensor socket or will a regular 7/8 or whatever wrench do fine?

    • @MrSubaru1387
      @MrSubaru1387  7 років тому

      +Evan Hartenburg an O2 sensor socket is heavily recommend. Using a normal open end combo wrench can round off the O2 sensor making it nearly impossible to remove. It all depends on how stuck it is, which they're normally in there pretty good due to the heat cycles. At the least I'd recommend a flare nut wrench if you don't have an O2 sensor socket.

    • @MrSubaru1387
      @MrSubaru1387  5 років тому

      85% of the time, a lean code is caused by a lean condition, not a bad oxygen sensor. Most likely you have unmetered air being drawn in between the MAF sensor and the cylinder head. So, loose intake ducting, bad throttle body gasket, bad intake manifold gasket, leaking fuel injector o-ring, etc. Or, you have an exhaust leak between the cylinder head and the oxygen sensor. Leaking exhaust manifold gasket, etc. I recommend using only the OE oxygen sensor. Aftermarket sensor tend to give incorrect readings. I believe Denso is the OE on the 2010.

Car has 46k on it mileage and is in good repair, I seem to have experienced a loss in gas mileage, that immediately improved following the cleaning of the MAF. But the error codes returned as I said.

    • @MrSubaru1387
      @MrSubaru1387  6 років тому

      P0171, system too lean bank 1. You have an air leak between the MAF and the combustion chamber. A common failure is the intake manifold gasket. With the engine running, you can carefully spray brake cleaner or carb cleaner around the base of the intake manifold where it meets the cylinder head. If you have a leak, the engine RPM will audibly change. You could also have a low fuel pressure issue, but isn't as likely.

      P0037, Heated oxygen sensor heater control circuit low (Bank 1 Sensor 2) This code is in reference to the rear sensor. You'll need to check the wiring harness and power out of the harness to the oxygen sensor heater. Usually a heater circuit is a burnt out heater inside the sensor, but sometimes it's an issue with the wiring or computer. If you just want to replace the sensor without testing anything, it is the post catalyst sensor.

    Mr Subaru - 06 Outback 2.5 P0420. Assuming this is a bad Cat do you have any recommendations for aftermarket replacement? Would replacing Front O2 sensor help? Car has ~= 170K. Any opinion on Pacesetter 324094? Many thanks..

    you still active? I am having a wretched time trying to find a downstream sensor for sale on Amazon. I did find one seller that was selling a sensor that claimed being either "down or upstream". Is that right? These can work in either placement??? I have a 1993 Legacy 2.2L Also, their chart says it is for the "BEFORE cat converter". Does that mean upstream? why can't they just use the same terminology? I'll assume upstream means "before" and continue fruitless searching for a downstream "after" sensor that's not a universal kit. any info welcome.

    My 2000 Subaru Legacy GTB (JDM) is having an idling problem in neutral. It cannot maintain ~1000RPM in neutral. There are no performance issues but it will stall if left in neutral for long enough because the rpm gauge will drop and rise from 1000 until it eventually dies. Would this be from the O2 sensor?

    • @Romulan112
      @Romulan112 6 років тому +1

      If you plan on doing the job, stay away from the oxygen sensor tools. Most sensors that i take out are always frozen. Using a crowfoot type socket/wrench will usually break the tool. i just did a 2006 Outback and used a 22mm deepwell socket with an 18" breaker bar. After I used all my strength, it gave and out it went. Doing it this way, you cut the wire to the sensor for socket accessablity. Also, dont bother using w-2 40 on it. It has a washer type shield that keeps your liquid from finding its target.

      2) Disconnect the battery for 30 mins.
      3) Reconnect the battery.
      4) Before you start the car for the first time, turn the key to the ON position but do NOT turn the engine over. Wait 10-15 seconds so the electronic throttle body or IACV has time to go to the factory programmed home position.
      5) After waiting, start the car and let it idle without any load, lights, A/C etc.
      6) Every 20 seconds or so the idle will be adjusted up and down as the ECU tries to adjust it towards a stoichiometric fuel / air mix.
      7) Leave the engine running for a full 10 mins but DO NOT TOUCH THE ACCELERATOR during this time or turn on anything that will cause extra electrical current draw.
      8) Turn off the engine, and leave the key in the OFF position for at least 20 sec.
      9) As per step (4) turn the key back to the ON position for 10-15 sec without actually starting the engine.
      10) Start the engine and leave to idle for a further 5 minutes without touching the accelerator and without turning on other systems in the car.
      11) Turn off the engine again and wait at least 20 sec before restarting.
      12) Take the car for a test drive as the ECU should now be fully retrained.
