January 22, 201610 yr 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.
January 22, 201610 yr Google the code. It is a fuel too lean condition. Lots of possible causes. Will give you things to check. O.
January 22, 201610 yr 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.....
January 24, 201610 yr Author 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.
April 1, 201610 yr 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?
April 2, 201610 yr Author 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?
April 4, 20169 yr 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..
