Wallis_93 Posted January 22, 2016 Share Posted January 22, 2016 My 2003 Subaru Outback H6 sedan with 156k miles just threw this code. The person at autozone said something about a MAF sensor but it appears our cars dont have this. Someone said something about cleaning the PCV valve or just buying a new one altogether. Any advice or recommendations? Planning on driving my car for the next week until I can fix it. Quote Link to comment Share on other sites More sharing options...
ocei77 Posted January 22, 2016 Share Posted January 22, 2016 Google the code. It is a fuel too lean condition. Lots of possible causes. Will give you things to check. O. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted January 22, 2016 Share Posted January 22, 2016 I'd want to inspect the fuel pump's cap and o-ring could be anything that throws-off OR confuse the ECU about A:F ratio. MAP, front o2 sensor, vacuum leak..... Quote Link to comment Share on other sites More sharing options...
Wallis_93 Posted January 24, 2016 Author Share Posted January 24, 2016 Well my check engine light went off after driving in the snow for a little. Guess I'll have to see if it comes back on. Quote Link to comment Share on other sites More sharing options...
JRSFleming Posted April 1, 2016 Share Posted April 1, 2016 I have the same code.. it keeps appearing.. I've taken off the MAF, cleaned with brake cleaner (non residue), and have put sea foam into the tank x 2 now, am currently checking vacuum hoses and looking for leaks there too.. no luck on finding those yet.. but the code continues to trigger.. I've read that it might be a bad EGR valve too.. but last night on my OBD DIag. and reading in another forum found that the Long term fuel trim and short term fuel trim readings (in a percentage) should not go higher than 14% when added together, I actually watched the long term steadily climb and the short term eventually as well. and I could see it was a pending code on the OBD Diag tool.. see the difference in the two screen captures.. Anybody have any other ideas? Quote Link to comment Share on other sites More sharing options...
Wallis_93 Posted April 2, 2016 Author Share Posted April 2, 2016 Mine still comes on and goes off. I also haven't found out what is causing it. I have noticed that it will usually come on after some hard pulls; usually after driving for a couple miles. Then maybe less than 50 miles later it will go off again. Have you noticed any trends with your driving habits? Quote Link to comment Share on other sites More sharing options...
JRSFleming Posted April 4, 2016 Share Posted April 4, 2016 The check engine light triggers after a trip of more than 20 or so miles.. turn off engine for a short time, like filling up or shopping.. then back in and start up.. the engine is not all the way cooled off, however after a long trip, no stops, turn off and the next day start up.. no light.. it's weird..
