Following-up on the post a few days ago. My 2018 MAX was complaining about the catalytic and emission sensor systems. Other high-mileage owners have began replacing converters, so I assumed it was my time. Being a little short on funds I thought I’d find a quick (likely temporary) work around by removing the converters and using a tuning program to shut down the system.
First, I shut the rear emission systems down. Took the truck for a drive. No new lights. Ran great. Like really great. Which told me the ecm was pulling performance out. And I had isolated the problem. (I’ll relay the specific codes when I get back on the tuning program.)
Next. Why stop there? Just cut them off. So I straight piped it. Started it. Didn’t sound any different, but I immediately had a new service light about an electrical issue with the emissions. Took it for a drive. No annoying droning. Ran ok… Like maybe it was pulling back again with the CEL.
My solution now is to plug the converter sensors in and secure them because I think it still detects some error in electrical current. I’ll do this and report back in n this post this weekend.
Then I got to looking at the converters. There is absolutely no signs that they are clogged. As well as one can see through them I see clear sharp honeycomb all throughout. People are replacing them at 130k. I’m currently over 140.
With that said, I think I’ll definitely pull the y and reinstall them. Even though there is no droning or sound change really at all, the smell is too much for a garaged vehicle. Wife isn’t happy.
Do what you want with that information! Thanks
