Engine Light Blinking

[Holly1385]

We have a 2017 Thor chateau motor home class c . We are taking a trip to Florida from Pa. we basically drove straight down here and only stopped for gas. I did notice when filling the tank 1/2 times he didn’t shut the engine off :/ so about the end of South Carolina / Georgia he noticed the check engine blinking . It would blink 2-3 times then nothing . And a while later it would do the same thing again. It isn’t staying on steady . We finally made it to our campground and while we were parked and running it was still doing it but more .

We literally just had our inspection done not even a week ago , oil change , filter , generator serviced . Said everything looks great . This is our second trip to Florida with this not even 30,000 miles on it and we maybe went to 1-2 other close trips to home with no problems last year at all .

Any ideas of what this could be . We’re sitting waiting to check in now and hoping the break will help it ? As long as it turns back on we hope

My mechanic checked our transmission fluids etc and said we don’t need servicing as of yet everything looks great . Really hoping in 5 days we can make it home . It sounds like we’re a small single engine airplane coming your way


Any advise would be great we’re so stressed out with all the problems since the inspection !

If it is blinking - STOP IMMEDIATELY!
Blinking means there is a serious issue. If you drive on you could destroy the engine.

Have it towed to the nearest Ford truck repair shop.

See if someone has a obd scanner to read the codes. Then google the code and that will point you in the right direction. Many of us have a scan gauge that will be willing to let u use.

It might be just a loose gas cap or something more serious.

What are the engine vitals, engine temperature, oil pressure? If those are ok, you should be able to drive it to a service center, but I would not ignore that light.

You mentioned you stopped for gas.......make sure the gas cap is on tight. I am not sure if a loose gas cap will cause a code ......but it does on some vehicles. Just turn the gas cap until it clicks a couple times so you know its on tight.

most auto parts stores will loan you a scan tool. Its easy to check it and reset the code if it is not anything serious. If it is because cap was loose when engine is running, tightening the cap won't reset the light. Only a scan tool or a certain number of key on/off cycles will erase the code.

I'm going to say this again...

If the check engine light is on solid, you can drive to a dealer. If it is blinking, you should stop immediately and have it towed.

A lose gas cap will produce a solid light. Not a blinking light.

From carmd.com

A flashing CEL (Check Engine Light) is something serious to be concerned about. A blinking CEL indicates that your vehicle’s engine is misfiring, which could severely damage your catalytic converters.

A misfire is when one or more of your engine’s cylinders are not providing power to the vehicle, with raw fuel possibly running into the catalytic converter. Engine misfire is a severe condition that requires immediate attention to avoid expensive repairs or even a car fire!
