SOURCE: 2006 Subaru ABS light and check engine light on, snowy conditions

An addition to my previous post (after talking to my husband more). Three of our wheels were snow packed. Not the wheel wells, but the inside of the wheels. He thinks that this is what caused the problem. The ABS sensors are located there. Having them encased in snow was likely what caused this condition. Solution = clean all the snow off your tires -- and the problem should go away. Sounds like the problem is moisture gets into the ABS sensor or something shorts out with the communications to those sensors.

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

SOURCE: 2006 Subaru Outback: all of a sudden, the cruis

Hello, whenever the check engine light comes on the cruse light will flash as well, that is normal. The check engine light will not come on if fluid levels are low or if the temp is getting to high, I am pleased to know that you checked all of the fluids, most wouldn't have even the slightest thought to even try checking them. The On Board Diagnostics or OBD-2 for short only sets a check engine light when the ECM or Electronic Control Module reads a sensor value either too high or too low, but it has to read that same fault 3 consecutive times in a row to turn on the check engine light (w/ flashing cruise). Otherwise your check engine light would be going on and off all the time. I would go to your local parts store and have them check the codes for free because a dealer will have to charge you labor for them to check due to the knowledge needed to use the highly sophisticated scan tool they use. That way you can go either to an independent shop or a dealer with what the other scanner says is wrong which cuts down on the cost of repairs. They will probably ask you if you fueled up just before the engine light came on, in which that would be code P0440:EVAP leak(very small leak), that means the fuel tank sensor doesn't like how you put the fuel cap on. Subaru recommends AT LEAST 3 clicks when tightening your fuel cap. But until that code is checked you won't know whats wrong, if nothing went boom or bang you'll probably be ok. If it does end up being a fuel cap leak, then just loosen the cap put it back on and just make 1 full revolution, and just keep driving it. The light will go off within 3 full warm up cool down cycles or (drive cycles). I hope this info helps...(subyguru)...
