That or just clear the codes with the scanner.

Really? Not being a smart@$$, but the gas cap doesn't take much before it's tightened. My gas cap barely turns 25 degrees before getting the tight click.

Yeah, I always feel like it doesn’t take much to get the first click, but when I had the codes checked it was throwing 12 repeating codes for the fuel door not being turned enough. Maybe with my Z approaching 200k, the sensor there is just “old”. So I just make sure it’s for sure snug now.

The sensor is a pressure sensor. It doesn't care if the cap is actually there as long as the tank is sealed. It's possible that the sensor is going bad but that would be very low on my list.

Check the threads where the cap screws in and make sure there is no dirt. Check the o-ring on the cap (a very small coat of grease may help it seal*).

It might be time for a new cap.

*The grease will tend to capture dirt but only when you have the cap off.

The SES light was caused by a loose gas cap that kept the engine from revving past 3500 rpm?
