Subaru Check Engine Light Lit And Cruise Control Light Flashing Fix

If you have a Subaru, and the cruise control light is flashing and the check engine light has come on, this video shows what can be causing it. The most common cause of a Subaru check engine light being on with the cruise control light flashing is a loose or missing fuel cap. In my case, someone lost the gas cap on my car, which caused the check engine light to come on and the cruise control light to flash. When this happens, there is nothing wrong with your cruise control. Tightening the gas cap, or replacing it will fix the problem, and the lights will eventually go out while you are driving. Watch this video if you want to know how to fix w Subaru with the check engine light lit and the cruise control light flashing.
Here's where you can get a Subaru repair manual:

Was going on a late night ripper in the 2.5 Saab and had this come on after fueling up. Immediately check online and find your video. Thanks for providing quick clarity without bs

Thank you. Just filled up my 2012 WRX on a 33 / 91 degree day. Took car to hand wash, super humid inside. Engine, traction lights on and Cruise flashing after car wash. Removed gas / petrol cap, pressure release evident, start car, no more warning lights. Cheers, JAYTEE

Thanks! This post and the comments helped me go from panic to calm after a bit of work. Cleaned and tightened down my gas cap. Started engine and still saw the flashing cruise and constant check engine lights as well as that skidding car icon. Opened the hood, disconnected the ground cable from the battery for a short while. Reconnected that then started up the engine to see things back to normal. Sure am grateful for resources like this versus the "old days" where I might have been forced to take it to the dealer and believe what they diagnosed was the problem. Surely Subaru could add a "check your gas cap" message or icon.

Pro Tip: If you loose your gas cap, go to a large gas station like QT. Tell them you left your cap their a day or two ago. They usually have a shoe box with 4 or 5 caps in it. Take the box to your car and use the one that fits. Don''t believe me, ask next time you get gas just to see.

I tried this bit still was on, so then i did the following, Disconnect the battery positive and ground cables for awhile, also connect both cables while Disconnected from battery terminals, turn headlights to on to remove any residual power, wait for some time. Reconnect battery terminals and proceed to idle relearn procedure. Took my engine light and flashing cruise away immediately in 06 forester, I Disconnect overnight .Cheers

Thanksgiving morning my 2006 Subaru Forester using my cruise control it went out so later I watched a few of the videos to see how to fix my blinking cruise control light and check engine light, so I got a new fuel cap and replaced a fused for air bag and the ignition sts air bag fuse too. Took a little rime if driving it but. Went back out to drive a quick errand and it reset itself. This information was very helpful and glad it wasn't more serious than it was.

2008 Subaru Liberty 2.4L Wagon

These 3 same dash lights appeared, the codes all read to airway : intake issues, I replaced the air filter & cleaned the mess sensor as it was dirty, I was low on oil, I also put in some fuel injector cleaner & I drove away dash light free : wasn’t the fuel cap for me !

There are several things that could be causing this. I did a fairly extensive search:

1. Go to a good autoparts store that will use a code reader to plug into your car, for free. (Autozone is one). Get that code, write it down. Do a search for the code.

2. There's a fuse that can blow, causing this. Sometimes happens after you swap the battery, or a deep freeze/heat wave. Finding the right fuse can be tricky.

3. Try unplugging your + battery cable. Wait a few minutes. Put your foot on the brake (to drain any last power lingering). Wait a few minutes. Plut the battery + cable back in. Start the car.

There are several check engine light triggers that also nix the cruise control. Cat converter, O2 sensors, fuel sensors, many more. Go back to #1 above.

Dude, i just saved time and money, God bless you!!!

[dongalbraith]

Same happened to our 2009 Subaru. It was a loose negative battery cable.

[tstoumbaugh]

replaced my gas cap but had to unplug/replug my battery to reset the codes and it was good to go, thanks

[josephdykes]

Disconnecting/reconnecting your battery, after the gas cap replacement may have worked too. Worked for my 2014 Forester

In my 08 legacy it got a p0420 code which was catalyst below threshold bank 1..ik this video is 4 yrs old just came across it..

[bennylloyd-willner]

Perfect! I just bought a 2004 Legacy and this happened when driving. I checked the cap and opened and closed it. I'll reset the light with my Foxwell if it doesn't go away until I'm back home, got a few errands to run so multiple on/off might do the trick🤞

[nathanhannah]

Had same issue. Took a week of driving to and from work and other trips, but light went out.

2011 WRX…I take fuel cap off, put back on, cycle ignition 6 times, gone.

[rodrigojoaquinrojobetancou]

Very good. I installed a new gas tank cap but it didn't solve the problem. It's been 4 days and still the signs continue. Could the problem be something else? I have a 2014 Subaru Forester.
