Sensor & gas cap
I have a 2009 Jeep Wrangler with 50k miles. My sensor came on Friday morning. The manual indicated it could be the gas cap or bad gas. I was down to about 1/2 tank of gas, so I had not just filled. I decided to try the gas cap. Bought a new gas cap from AutoZone on my lunch Friday. The sensor went off on Sunday, but then "gas cap" dinged at me. I pushed the trip to turn it off. On Monday I took it to get an oil change they hooked it to the diagnostic and it was the battery. Replaced the battery and everything is fine. Put my old gas cap on and no problems since. I guess I thought if it were the battery, the battery light would come on. But that was my fix. Good luck and have your battery checked if this happens to you.
