In this video I am working on a 2014 Subaru Outback with a 2.5 and CVT. We have done quite a bit of work to this car to solve an ongoing P0420 code. Make sure, especially on a Subaru, that you complete all troubleshooting steps before replacing the catalytic converters as they are very expensive.

Sounds crazy but make sure your gas cap is closed and the seal is good. If not you will get a few codes.

Well I had that problem for over a year. Light come on then go off for a while. and this spring I took a chance and cleaned my Mass air flow sensor. An 300 miles later still no check engine light. and I believe my problem is solved.

It is very important with the P0240 code to ensure all systems are working well before replacing that cats. Good job!

@edashton1662 I'm not entirely sure, I got the car about 8 months ago and it's been running great with no lights on, I got a 2004 wrx STI with a full catless exhaust system. It feels pretty smooth and runs great even with the CEL on, I drove it from Denver to Idaho springs CO yesterday it's like a 40 minute drive It's worth mentioning I pumped some gas up in the mountains, also I didn't do any pulls or anything I was simply coasting at 3k RPM when the cel popped up, the cruise control also started flashing ( I have a detachable steering wheel ) the car feels great I just don't know what this dam code is all about

Just purchased a 2014 outback and within 24hrs got this code. Does the brake light and cruise control lights blink as well as the check engine light being on? Because that's what mine is doing and I'm freaking out.

@richarddubord3978 8 ай бұрын

yes, it is normal for them to be on as well as the check engine light

I changed my O2 sensors. CEL still comes on :(

Make sure your spark plugs are new, air filter and mass airflow sensor are clean. No vaccuum leaks, etc. Make sure your exhaust pipe isn't crimped or crushed. There is also another check you can do. You can purchase a not very expensive gauge that screws into the O2 sensor port ahead of the cat and it will tell you if you have an exhaust blockage.
