YES!
Engine that was operated with a loose , missing or bad fuel cap.
96+ vehicles missing the fuel cap will activate the check engine light and set an evap system gross leak code. If your temporary cap seals properly and is correct for the application there should not be a problem.
Yes, this is often the reason why the check engine light comes on.

No. However, some cars will display a "check engine" light on the instrument panel if the gas cap is loose or missing.

Yes, a missing reservoir cap can cause overheating in a vehicle. The cap helps maintain the pressure in the cooling system, which allows the coolant to circulate effectively and prevents it from boiling over. Without the cap, coolant can escape, leading to a loss of fluid and decreased pressure, which can ultimately result in overheating of the engine.
Have you noticed if the cap on your bike tire valve is missing?
The check engine light indicates a problem with you engine that may or may not affect the way it runs, the only way to tell is to have the codes read at the dealer or a parts store that will do it for free and use the information gained to affect a repair.
Depending on what year Jeep you have, it may cause the check engine light to come on. It won't effect how the engine runs but it will effect the emissions.
It could be that you have not tightened the cap on your gas tank. Be sure to check the gas cap and see if its being properly tightened. That was the case for me a couple of times.
make sure gas cap is on all the way or missing cap ,this car must have a gas cap or computer will read [large] emissions leak or emission gas cap, hope this works!
