Evap still not ready

I left the spacer in, I also did about 160 miles at 80mph. The spacer I was using (a generic from Autozone) never seemed to get enough airflow to become ready. I drove for 3 weeks and even did the whole 55mph slow to 10 thing which worked 100% of the time without the spacer. So I left the spacer on, but i really had to go a long distance at a higher speed for it to come ready.

I'm through inspection!!!!! Let's see about the evap

Thanks for the link! I'm fairly positive Delaware says all monitors have to be ready, but at least I can try! https://www.dmv.de.gov/VehicleServices/faqs/index.shtml?dc=ve_faqs_obdi#:~:text=A%3A On-Board Diagnostic systems,repair technicians and our environment. but then I see this from reddit r/Delaware/comments/xcwymw/delaware_dmv_question_readiness_monitors/

Spacer is attached yes, all sensors are ready except for EVAP and currently have 0 codes. So, now I just need to get the evap ready...

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?

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...

Just to make sure we're on the same page. 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.

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...

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.

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). The problem with the spacer is the 02 sensor never came ready. 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. And yeah, this Frankenstein swap is a PoS, the shop that I wanted to do the work told me they couldn't get the 2.2 and they said the 2.5 would not be a problem, I've been stuck with this issue since... 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)

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. They believe the front cat isn't going a good enough job and that the back cat was replaced with an OEM cat.. 1400$ qoute... i feel like this isn's right

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?

Okay the P0420 just came back just after I wrote that post. 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...

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...

How do you trick the system if the 02 won't come ready? Or are you suggesting putting the 02 back the way it was resetting everything and moving forward?

I honestly don't know, I'd have to go and look. I was originally getting a P0420 which is why I got the exhaust work and the O2 sensor put on. When I put the new O2 sensor of the P0420 came back so I tried the spacer route. The problem now is since I put the spacer on the 02 sensor won't come ready (6 tanks of gas 1300 miles later in both highway and city). Part of me wonders if I should take the spacer off, let the p0420 come back, put the spacer back on and see if it goes away. I also never had a p0440 until the spacer, but that could just be a coincidence.

Hey, sorry for the confusion. There are two issues currently ongoing. One is the 02 system won't come ready an the other is the P0440 which I wanted to smoke they the car to find the leak. To answer your question, the 02 sensor is about 7 weeks old, bought brand new from Autozone, and quality I believe is only one they carry?

I truly appreciate everything, I'll be able to hop under the car this weekend. Quick question, your link is for a 02 outback limited wagon. I have an 01 Subaru Impreza outback, does the same diagram work? Also, At this point I've now driven 1300 miles, have the po440 code and the monitor is still not ready for the 02, all i can think or is either the O2 sensor is fried or the spacer isn't reading correctly where it'll become available. I'm going to get the part you have above and replace it, but I can't think after this long something isn't right. So I got a tool and yeah the 02 is still not ready and it shows the 1 code. It's almost like nothing is getting to the O2 sensor. Is there a way to smoke test or easy way to test this? Nothing looks out of the ordinary other than it's old and it seems like a lot to just replace it all.

I'm priobably going to start a new P0440 thread, the gas cap didn't do it. I'm going to wait for Tuesday to verify that the P0420 wen't away when I take it to DMV to see if the monitors are ready.

Thanks! I know when I reset the code for the P0420 it took about a week for this check engine light to come on, hopefully it will go away... hopefully.. If not, guess I am troubleshooting P0440...

Okay, so the check engine light finally came on, and this time I don't have a P0420 at all I have a P0440. I took it to autozone and their print out says check the gas cap, well I legitimately don't have a gas cap so I put one one. So I guess my questions are, one do I not have to worry about the P0420 anymore? I don't know if the sensor is ready until I go to inspection on Tuesday. I also, bought a gas cap and put it on, do I have to reset the code and wait? Or will it clear itself because it thinks it's fixed? Also, I've never had a P0440 code until now, would the space cause it? Thanks!

Sorry for the ambiguity. The check engine light is not on and when I go to inspection the monitors are not ready (O2 and Evap), The vehicle is not a 96, the vehicle is an 01 which originally had the 2.2 now now a 2.5, I also have no idea what the 2.5 came out of. I've now driven over 800 miles and done everything in the list below, and several other sites/forums suggestions. I'm starting to wonder if the spacer is causing the monitors to not be ready. https://www.suoutback.com/drive_cycle-1102.html LOL, not a Studebaker, but also not a turbo, N/A, Impreza

Thanks, here is a question about the spacers, do you stack both together or just 1? I have tried this route and now have driven over 300 miles with every stop and go, idle, and coast and heat on and heat off and cold start and 1/4 gas tank and I cannot get the O2 ready to be ready. Thanks!

Long story short, I had a 2.2 and got swapped with with a 2.5. I replaced the cat because it was legitimate snapped in half and I also replaced the 02 sensor, all together I am about 1200$ in the repair of exhaust and sensor and I'm pushing the car's value. My question is, with the swap of the 2.5 could I be having other issues? Since I've replaced the cat and o2 sensor, is there only things I should take a look at? There are no other codes on the car but I do remember reading about a mass air slow sensor? I took it to a good shop and they said there doesn't appear to be an electrical issue. Any advice would be great!
