check engine light with flashing cruise control light
Checked codes at Auto Zone: catalyst efficiency low-bank 1 probably cause: CC failure possibly due to: (1) engine misfire or running condition (2) large vacuum leak (3) engine oil leakage into exhaust-valve guide, seals, piston rings.
Less than 52K mis -- shouldn't be CC, right? Likeliest cause? A mechanic said they'd have to due a smoke test, service meter, and induction test (for $70 each). Also said there are 3 CCs on the Forester. Any suggestions would be welcome.
I found an answer on another post. This seems to be an ongoing problem for the Forester. People have had lots of work done at Subaru without fixing the issue. I'm going to try to following suggestion: plug in MAF sensor after replacing air filter with an after market. Unplug battery for 1/2 hour. If that doesn't work, I'll try replacing the oxygen sensor and resetting the computer.
Two foresters 06 and 08, both do this periodically, engine and check cruise control lights. Dealer can find nothing, they stay on for awhile then go out after a couple weeks. I ignore it now. Nothing has happened to the cars since. The 06 did it within a year of buying the car, the 08 started within about the same time period.
2005 forester, just recently had blinking cruise, solid lit CEL, going into dealership this week, posts were extremely helpful to a single, 62 year old female, THANKS...will post outcome, and if not guaranteed to resolve issue, will take advice and do nothing...when I did call dealership, they did say "no worry" if CEL is solid and not blinking as if they are quite familiar with this sort of problem...will post at later date..Diana
My 2007 Forester had CEL come on with blinking cruise (and cruise dosn't work either) about 35 miles after i filled up at a non-mainstream gas station. I turned to the owners manual and i guess the Forester can be picky. The manual (see 7-2 in 2007 owners manual) states that some gas stations put an "...octane-enhancing additive called MMT (Methylcyclopentadienyl Manganese Tricarbonyl). If you use such fuels, your emission control system performance may deteriorate and the CHECK ENGINE warning light/Malfunction indicator lamp may turn on." That being said, i currently have a FULL tank of crappy gas...does any have a recommendation of what kind of additive i should put in to make the gas better.
not sure if this will help anyone but our 2007 2.5 turbo had the blinking cruise light and engine light on. we have found out its the fuel cap, it has a small sensor on it, and when released to put fuel in and replaced it can set the lights off up to a day later?? yes the forester can be picky
I had the same issue with my 07. $5200 later it was rectified. Bent valves, compression leak.... The list went on. apparently its a know fault with is model. Anyone else in the same boat??
Bent valves? That really only occurs if the timing skips, and is not common at all.
Glad to report that the solid check engine and the blinking cruise lights shut off this morning. Three days of anxiety over! Thanks for this forum and the above answers. Undoubtedly saved me hundreds of dollars. The dealers here in South Jersey just love to take us for a ride.
jmarie220, how? how did it turn off? it bugs me for months now, the computer has allegedly detected secondary air pump error. when replaced, it was off for some 200 km, then went on again. (same thing - cruise blinking , CEL constantly lit). i do have gas built in on my 2.0 2006 forester, though, with oil droppers (maybe it is another expression, but lubricating the valves)
I have a 2006 Forrester L L Bean model and the check engine light went on causing the cruise to blink. Young Subaru charged me for hundreds of dollars for DX could nt fix it, after $900.00 worth of work, problem still persists. Now my headlights and tail lights stay on even when the car is off....frustrated. Have to disconnect battery to turn them off, anyone have any ideas?
Did you check the parking light on top of your steering column?
I was cleaning around that area yesterday, I didn't realize there was a switch there. I went out connected the battery and checked the switch and fixed the problem. I don't know why you would use them, I never have cos I didn't know I had them. I'm not blonde I'm a red head......lol. THANK YOU all who helped me with this question you were all helpful!
No problem, that's a rite of passage for every new Subaru owner.
I too had the Check Engine Light/Cruise Control flashing problem happen on my 2009 Forester. My yellow traction control light (squiggly tire marks behind car) also comes on. I went to a tiny garage in east Tennessee and they guy did a diagnostic and said that it is caused when you haven't had an oil/filter change in over 7000 miles or so (he checked a "code" database to find out). He changed my oil and reset the computer. All better. Then 7000 miles later (I drive a lot and sometimes miss my oil changes), the same thing happened. Got the oil changed again and reset the computer, fixed again! Happened a third time and again got it fixed, but this time they forgot to reset the computer. Lights came back on quickly, but I went back and they reset the computer and all has been fine. Since I've had my oil changed regularly, no repeats of the problem.
Ii has to be something with the transmission or front differential fluid from what I can tell. I've had it happen many times, and it has gone away on its own in some cases, but other times, the "fix' was to add fluid. The first time it happened, I had parked my car sideways on a steep hill for a couple weeks. Shortly after leaving, the car bucked and heaved if I accelerated too much, and those lights came on. Since then, I have had it happen after long periods without any problem when I hit the accelerator hard for whatever reason. My only remaining questions are (1) is it the transmission fluid or differential, and (2) why is it getting "low"?
My 2008 just stopped running 1 month ago. It continually had these lights come on when driving over 100 miles at a time on the interstate. Then it would jerk when accelerating. When it died, it jerked and just lost power. For a 2008 it should have lasted much longer and was regular maintained.
Follow-up: I just found answers to my own questions. 1. Its the front differential fluid. That makes a LOT of sense, since to problem first occured when the car was tilted for 2 weeks. 2. The reason its "leaking" is that I've been putting ATF fluid in there (the only thing I had on hand), and it needs a much heavier weight oil. 70W/90W.
