Driving home last night... gas cap light comes on. I tightened gas cap, restarted car and light goes off...started car this morning and now check engine light on

The "gas cap light" actually does not mean the gas cap is loose or defective.It is telling you there is a leak in the fuel system somewhere,usually a vapor line or stuck or defective valve.Not very often is it the gas cap that causes the light to come on.Time for a scan and a smoke test to fine the leak.

Gas cap indicaytor light came on. Changed cap and made sure it was tight but indicator light still comes on

The gas cap light is a generic light that indicates an emission problem. Usually a vacuum/pressure leak within the system. The gas cap is usually the first thing to check, however may not be the problem. There are numerous sensors and lines that control the vacuum/pressure/ of the fuel vapors and one of these is loose/disconnected/defective causing this light to come on. I would recommend inspecting hoses under the hood for any that may be loose/disconnected. You may also require a scan test to view sensor data to isolate the source of the light

Gas cap light stays on

Take off your gas cap and put it back on if that does not fix it so the light goes off replace the gas cap. This light usually indicates. A problem with the gas cap. It maybe on crooked or is not sealing properly in which case it would need to be replaced. It may need to be driven a few miles before the light goes off

Why would my OBD or malfunction indicator light come on and stay on?

Check engine light comes on with faulty oxygen sensor, loose gas cap or faulty gas cap. sometimes with low octane fuel as well. fill up with high octane fuel, tighten down the cap and see if it helps.

Low Fuel Panel Indicator On

I know if your gas cap is leaking the low fuel light will come on but I never heard of the gas guage showing empty unless you have a float problem. The float is in the tank.

Hi. this situation concerns a lose gas cap that you may have forgotten to tighten correctly during a recent fill up at your local gas station or, it could be that the original gas cap or replacement gas cap is not sealing the cap area correctly, preventing proper fuel pressure.

Check the gas cap to see if its tight and that it clicks when you turn it. make sure you turn until it clicks. this will ensure a secure fit.

Now, if you have just recently bought a new replacement cap, it may be the wrong fit and i would recommend purchasing the original replica form the dealership to ensure a tight fit.

Please rate and god bless:)
