Or are you suggesting putting the 02 back the way it was resetting everything and moving forward? yes get rid of the spacer, clear codes (did you buy that cheap code reader/eraser yet?) and see if the 0440 stays off then see if you can get the systems "ready". I can get my systems ready by following a procedure: gas tank 1/2 full drive 55 mph for 15 minutes without changing speed or braking. Slow down to 10 mph then accelerate again to 55. That usually gets the systems ready and then a quick drive right to the inspection station and I'm good for another 2 years. The 0420 is a code that has many possible causes and I refuse to throw my wallet at the great unknown. Sometimes the CEL goes off by itself but no rhyme or reason as far as I can see.

So, I took off the 02 sensor and cleaned it, for some reason it has some oil on it. I'm going to guess I have a leak in my oil pain... When I cleaned it and put the 02 sensor back in, and drove it like you suggested. When I did that, the 02 sensor came ready and guess what! No P0420, now I'm going to guess I got the P0420 from oil getting on the sensor? The only bad news is the CAT and the EVAP have yet to come ready, so I'm hoping I don't get the P0440 back...

brus brother Posted October 17, 2023 Share Posted October 17, 2023 But the oil wasn't on the internal aspect of the spacer?/ If there was oil internally, that cat is in trouble! Fingers crossed. at least 0440 gremlin s gone ... for the moment. I recall reading somewhere that you can pass with 1 (one) system not ready but I don't have first hand knowledge. Don't be discouraged if the 0420 returns as you haven't really done anything that would have cured the P0420. You likely just backed out of the 0440. P0420 is a real bugger but you can reset using your fancy new code reader (?) and hope you clear and set systems ready then scurry over to pass emissions inspection. We get a warning post card about 2 months before inspections become due so I have time to try and cheat the system. Just sit tight now and don't be tempted to do a reset as you will go back to having all the systems needing to reset. With the cel on, the cruise control doesn't work and a few dash lights are flashing but if it bothers you, a piece of black electric tape will cover the light 😉 Keep us posted Link to comment Share on other sites More sharing options...

The EVAP isn't ready yet so no idea if the P0440 will come back. I'm not entirely sure if the oil was on the inside of the spacer, it didn't appear so...

phyregold Posted October 18, 2023 Author Share Posted October 18, 2023 Here is the 02 sensor, it doesn't look terribly dirty. This is where the oil leak I have is coming from, it was running down on the 02 sensor wire, i'm assuming this is a pan issue... This is where we drilled it this is the exhaust Maybe I should have drilled the spacer all the way through? Link to comment Share on other sites More sharing options...

phyregold Posted October 20, 2023 Author Share Posted October 20, 2023 I took the vehicle to Scotty Muffler, and they told me they think I need to replace both the Front cat and the front o2 sensor.

Which has a really good chance of making the light go out. Do you know if they were quoting a new Subaru part or something else? If I was spending $1,400 it would only be for the Subaru part, no way I'm paying that for aftermarket converters. Which O2 sensors have been replaced so far and were they plug and play or wired in? Hopefully the right sensor is in the right location and they were wired properly if they're the generic loose wire variety. I'd also probably gamble on this: https://www.fastwrx.com/products/oxygen-sensor-spacer-with-cat Never used one myself, but for $50 looks awesome. it's like a mini converter right before your O2 sensor. If you're going to replace exhaust - it doesn't hurt to ask around and get a second opinion. Link to comment Share on other sites More sharing options...

Okay, so the p0440 is gone and the p0440 only appeared with the spacer. I actually have all the sensors ready and 1 code now (the P0420).

If you're going to replace exhaust - it doesn't hurt to ask around and get a second opinion. The rear sensor and the rear cat have been replaced. The front cat is the original 22 year old part. I called another shop up north and they will replace the front cat with the direct bolt-on for 900$ including the 02. The "gig" with Scotty Muffler is they are certified by the state, they said for 2500$ of work if they don't get the light to go off they can certify the car and the state will accept it. But I'd have to get that 2500$ of work every 2 years.

I just found it really super odd the o2 sensor would not come ready with a spacer and gave me P0440... If I put the spacer on now will the light just turn off or do I have to clear the codes? I feel like I need to find a shop who can actually hook it up to a machine and measure the o2 somehow, the actual flow or electricity and know what they are talking about, but honestly I don't even know what test I'd be asking for. this guy demos the test in his video. I hate to pay the 900$ and the front cat isn't the problem... May I should put the spacer on the front sensor (this is a stupid question - ignore this) Edited October 21, 2023 by phyregold Link to comment Share on other sites More sharing options...

You should be able to just put the spacer in and let it rectify itself and the light goes out. i routinely install the spacer and clear the code immediately because ivE never had issues with the monitors being ready. but yours seems different and doesn’t respond as we are expecting Your issues may be swap related somehow. You should easily be able to swap those motors with no issues. EJ25 swapped into EJ22 vehicles has been done thousands of times and those spacers are well known work arounds for pre 2005 Subarus. That’s why brusborthers wouldn’t work - his was a 2005 and that’s when immobilizer CANBUS and the O2 data starts to get used by the fuel injection. It’s much more sensitive. In 2004 and earlier the rear sensor is just a trigger for the P0420 code. You can completely disconnect the sensor and the car runs fine. Can’t do that 2005+. But clearly you have issues so it makes me wonder what all happened during that swap? Link to comment Share on other sites More sharing options...

All fantastic points and questions, the only thing I know of is the exhausted couldn't be correctly put together because it had way to much rust. I remember the check engine light was on before the 2.2 blew, but I have no idea what it was. I'll try the spacer again since all the sensors are ready and see if I can do the drive 55 and then coast to 10 and check if the check engine disappears. I'll let you know in a few hours.

Alright, so I put the spacer back on and then drove it about 30 miles and did the same thing which seems to bring the O2 sensor ready and nothing happened. So I stopped by Autozone and picked up Cat Complete Fuel, Exhaust & Emissions System Cleaner and nothing happened. I drove about 45 miles to go pick up my daughter, shut the car off and turn it back on, and... the light was gone!! So I decided to check it with the scanner but the scanner still found the code! My check engine light still works because i turn the key over and it lights up, but with the car running, it's gone. I'm so confused... Link to comment Share on other sites More sharing options...
brus brother Posted October 21, 2023 Share Posted October 21, 2023 (edited) I think it is normal that light being on with key in on position but goes off with car started? If the 2.5 came from a MY 05+ that might explain why the spacer trick doesn't work? You aren't sure where the 2.5 came from right? I seem to remember someone stating a number less than $2500 worth of unsuccessful repairs that gets you past inspection but don't quote me. Just checked in CT as of 2021 it is $1069 by a certified mechanic. In Delaware (you?) see https://www.dmv.de.gov/forms/veh_serv_forms/pdfs/D19477_ve_inspection_pro.pdf looks like it's $710 see section 3 in above link.

The engine light is off when the car is running. I only mentioned the check engine light was on because I was making sure the check engine light bulb worked. So the check engine light is gone, the check engine light bulb works, when I scan the car when the car is running the p0420 is still there.

My reader actually called it "pending" but I was using the very expensive $19 reader 😉 As I recall, if you use the scan tool or disconnect the battery to erase the code, you will likely have to again wait for systems to become ready.

Or do you just click "READ CODES" and it shows that code with no other information? Maybe it's seeing a code from memory? Ideally you clear the codes first. Then do your preliminary drive as brusbrothers stated. Then check the codes. This ensure they are indeed new codes. I hate to say it - but can you clear and do one more drive?! 1 hour ago, heartless said: the light off means the problem has been resolved, and that is all that matters Not all the time, there are "Pending" codes. It's best to clear first, run, then read. And ideally tell us how the scanner is working (read/memory/pending/etc) since each scanner has different user textual interfaces.

Okay, so it's a stored code that doesn't see a fault anymore, it's not "pending". This will still cause me to fail inspection. I'm going to clear the codes which will cause everything to become unready... but, maybe the difference is yesterday when I had to go pick up my daughter yesterday I was able to do 80 the entire way. This might be a difference because I typically only do 55-60 everywhere and my working theory is, if the spacer is indeed causing the sensor to not get enough information, then going 80 with the additional exhaust flow might have caused the sensor to receive enough information.....? Going to clear the codes and try again... Link to comment Share on other sites More sharing options...
phyregold Posted October 22, 2023 Author Share Posted October 22, 2023 Hah! Working theory proven. The spacer I'm using was unable to get all the information needed at 55, so when I did 80 to pick her up the exhaust must be able to push enough up to it... Now, I'm not sure why I was getting the random P0440 when the spacer was used, but wasn't when the spacer wasn't used. So what do I need to do to get the evap to come ready?

brus brother Posted October 22, 2023 Share Posted October 22, 2023 Diagnosis is tricky and can be challenging. This therefore that until... oh wait! Never mind. IIRC the evap was the last to become ready on my 05 OB. So is the spacer still in place? If the evap stays shitz, wasn't there discussion earlier about checking out evap system components located somewhere aft? waiting for the end credits to roll before I leave the theater.
