What is wrong if the check engine light keeps flashing

Does the scan tool light up, but doesn't connect. It could be wiring or the ECU. If the scan tool doesn't light up, check fuses. Most DLC connectors are power by the lighter /power point fuse.

There is a UFO flying near you.
wait until it passes, if your car still doesn\'t work, call the FBI.

tcm is going bad

Check engine light comes on constantly nothing seems wrong or Check engine light keeps coming on and something is draining the battery..Which is it ?

Dont drive a car with the light flashing. A flashing check engine light means that something is really wrong and you can damage the engine if you drive it.

which dash light if the check engine light is flashing theres a problem with your car have the code pulled

You might want to take your truck to another shop, when the od light is flashing, that's telling you there is some thing wrong with a sensor from your transmission, needs to be checked right or could cause major damage to your transmission, at the same time they can check the service engine light, that would be an engine sensor not putting out a good signal and the computer pick it up, if both light's are off now wait till one or both come on there won't be ant code's stored, hope this was very helpful.

if te check engine light is on the cruise wont work it just flashes if you erase check engine light and cruise still flashes hit cruise button twice it will go out but if engine kicks the check engine light it will flash again you have to fix what ever it is that kicks check engine light or you just deal with it

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)...

Take the car to an autoparts store and have them scan the computer for fault codes. Most parts stores will do the scan for free. The check engine light is to alert you that the computer has identified a fault in one of the car's systems. Getting the codes will show what the computer noted, so a problem/potential problem can be addressed. Hope this helped and best wishes.
