Check engine light

[Jq42]

I received the message below when leaving work. Don't know if this helps, but It was about 50 degrees outside.

WARNING: Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior floor covering

Has anyone had this same code?

That message was displayed in your instrument cluster message center?

You can go into 'Engineering Test' mode and get read trouble-codes. Just scroll through the menus as shown in the video until you see the DTC screen.

Nothing comes up on the dtc screen.

Sounds like its a misfire code then. PO3XXX or something I think is the misfire code start.

If it doesnt call out what cylinder is misfiring then it could be a random mis-fire.

have you done anything different to your car? Tunes? Gas? Anything but appearance mods?

Only JLT intake and muffler delete. No tune

Well the JLT requires a tune. Get it off ASAP.

My understanding that the JLT for ecoboost does not require a tune.

My bad, you're correct. It does on the GT's but not the ecoboost.

Could my mods have anything to do with this? Or could it be a glitch? I didn't notice anything different when the light came on.

If the intake wasn't installed correctly it would be a problem. Try putting the stock intake back on and see what happens?

I can do that, but the intake has been on for over 4K miles

That's strange. I would think if your Check Engine light came on that there would be a DTC stored even if it was an old history trouble-code.

Did you disconnect the battery at any time after the Check Engine light came on?
