cornick Posted March 10, 2010 Share Posted March 10, 2010 My wife was driving this evening and all of a sudden the cruise turned off and the CEL came on. Now the cruise indicator light is flashing. I pulled the codes with my [ame=http://www.amazon.com/Equus-3100-Innova-CanOBD2-Diagnostic/dp/B000EVWDAK]ODB2[/ame] reader and it pulled a P0420. Couple side notes that might be important: 1) A phone car charger broke inside the power adapter and a couple sparks popped a week ago. Since then, the seat warmers don't work. 2) Had to connect the muffler and pipe together due to a fitting rusting away over the summer. 3) Have had on and off issues with the cruise not wanting to engage...for the last couple months but it was so intermittent that I didn't pay much attention to it. 04 Legacy Outback Sedan 69k miles and out of warranty Any help would be appreciated.

cornick Posted March 10, 2010 Author Share Posted March 10, 2010 Just called my local dealership and they said the only warranty that would be left is an emissions warranty. Does that code fall under it? Link to comment Share on other sites More sharing options...
burnout8488 Posted March 10, 2010 Share Posted March 10, 2010 If you're from the US, (I'm assuming you are) your car would fall into the "3rd Generation" forum, but this is a pretty generic problem. Sounds like an O2 Sensor or Catalytic Converter type problem...... therefore you MIGHT get lucky with an emissions related claim if it is the cat. As far as the phone charger problem, your heated seats are probably on the same circuit as the 12v accessory outlet. Check your fuse and report back Edit: Make sure ALL exhaust leaks are patched up around the catalytic converter/engine. That could falsely set a P0420 as well.

According to the layout of the forum the third generation only goes to 2003, that's why I posted in this one.

They said I need to bring it in and pay $107 for diagnostic to see if it will be covered.

Check your fuse and report back That's what I was thinking as well but wanted to hear someone else say it for confirmation.

cornick Posted March 10, 2010 Author Share Posted March 10, 2010 I just went out and tried a couple things I read on the forum. Starting it 4 times...holding down the brake for 30 seconds... after the fourth time it didn't even start. Cleared the codes and it was starting REALLY rough...which is very abnormal for this car...normally it just turns right over. Link to comment Share on other sites More sharing options...
burnout8488 Posted March 10, 2010 Share Posted March 10, 2010 Interesting.... with an "inefficient" cat the car should still run, and start... Maybe the O2 sensor is toast? If it's giving the ECU a bad reading, things might go haywire. Also, try cleaning your MAF (Mass airflow sensor). I had a dirty MAF and it resulted in a P0420.

TattooAddict04 Posted March 10, 2010 Share Posted March 10, 2010 I had this problem come up as well, but mine happened in a blizzard we had a month and a half ago. But once i got out onto pavement and turned off my car and started it back up it was gone. I'm assuming snow got stuck up and maybe screwed up a sensor. Not sure if it has snowed by you recently. I now have an excuse to order a rallitek skid plate though:lol: Link to comment Share on other sites More sharing options...
BruceBruce Posted March 10, 2010 Share Posted March 10, 2010 my car has been popping a po420 code a couple times. first time cleared it hoping it would just not come back. 2nd time i cleaned the maf and it went away for awhile. 3rd time it came back i took it into the dealer and told them i had a p0420 code and wanted to know if this falls under the cali emission warranty. they said yes and after doing whatever it is they do for 4hrs with my car they are now ordering me new cats as well as doing the fan recall on monday.

Bublz81 Posted September 27, 2011 Share Posted September 27, 2011 2008 LEGACY.....CEL and Flashing Cruise I had this happen when I had my battery replaced and the Les Schwab I took it ran a diagnostics and nothing came back and they kept resetting it and they kept coming back. I took to a dealer and this ended up being a fuse that needed to be replaced, which caused the error as it wasn't able to communicate with the computer. This happened just the other day again and the PO420 code pulled up on my boyfriends diagnostic tool... My question is if this is one of the 02 sensors or tht CAT, how much am I looking at on average? Anyone know? Link to comment Share on other sites More sharing options...
