Anyone know what those mean? I did already check the gas cap.

Blue Toy, I hope these codes aren't the same as FORD's. Those 400 codes was my biggest troubles on my 03 F-150. 10x and they gave up trying to fix the truck Got apologies excuses you name it from all of the managers. They even went an jerry-rigged a wired to the sensor from outside of the harness to try and stop the code from showing up. The first time they gave me the gas cap routine with this explanation. It takes 8 cycles to clear the code. Meaning start, run, stop, one cycle. So 4 days later light comes on same 400 code. replace sensor. Test new sensor pass. 2 days later you guess it 400 code bad bad sensor again. Test sensor by itself pass. Test sensor with whole system failed.
Yes the tech was that pic. 5 days later again it happens. Ordered computer. Statement "We never had problems with a computer". My statement "Never say Never". Change computer #5 cylcinder missfires. Get computer from truck on lot. #5 cylinder missfires. Put original computer back in engine runs fine. Next day check engine light 400 code again. Try computer from different truck on lot. Yep you guess it #5 cylinder missfires. This went on for 10x. All manager and my service advisor and my salesman tell me the news but my salesman being the great guy he was, stated replace the truck with a new one. I agreed right away. Little guy to right the Laison to Ford manufacturer kept yelling "You got to pay mileage". I almost grabbed him but my salesman Rusty got in the way and told me let's go order your truck. I was satisfied with that. It would take 6 weeks to come in. Happy with that. Rusty stayed in touch every week. One week left get phone call to bring truck in. I'm thinking my new truck came in so I showed up there 2 days later. I was out of town. When I get there they hold my truck and state Factory guy will be in town in 2 days. Asked Rusty he showed me the printout that the new truck will arrive in 2 days. I was called in the next day when the rep was there. He tells me there was 3 trucks in numerical order with the same problem. Two on west coast and yes I had the stepchild on the east coast. Turns out the pins in the wiring harness along with the computers were different. The pins were short. This caused the missfire along with the sensor problem. So he fixed it along with making the dealership fix back to original that jerry-rigged wire to the sensor. Rusty tells me to come in the next day because the truck will be delivered in the morning. I showed up and low and behold FORD states your truck is fixed so no new truck. After 3 days fighting I still loss to Ford. But that didn't stop me I went and traded it in for an 06 Silverado LT3 which was just as bad. Sorry about the rant but that 400 code brings back bad memories
