This is the inspection cover, remove it and see how far the tensioner has extended. If you can see lots of shiny shaft and several 'oil bands', then your chain has stretched.

Also, here's exactly what the tensioner looks like......

Awesome, thanks. The truck runs great, pulls great no hesitation in throttle response, idk if any of those are signs of a stretched chain. I also don't want to think this but am hoping that a dealership is trying to compile more and more things wrong with the car than actually are due to the state of the world. Also can't believe they quote you $70 to change the license plate bulbs 😂 but I got bigger problems than that.

Mine ran fine for 12 months with the code. But my chain was most definitely stretched when I got around to replacing it.

Btw, the only special tool I needed was the crank pulley bolt remover tool. I still have it....

Awesome thanks everyone. Also, the only reason this came up was because on my way to dropping the car off at Toyota last night my dash lights lit up. Engine traction vsc off and the other one. I read that it could just be the gas cap, had them scan for the check engine and they said it was the OCV. So idk if it's the gas cap, Ocv or potential timing chain. I'm not paying for any of it today so just trying to figure what everyone thinks my next step should be.

Got back from the dealer, the gentleman inspected the timing chain and said everything looked good. They also said both #1 & #2 OCV's looked good, but he recommended changing #1. Just odd. Thankful for the chain being fine. Thanks everyone.

I'm not worried about time. Thanks.
I have a bit of experience. Ive pulled engines, done headgaskets, clutches, turbos, etc. This was a ***** of a job. Sealing the timing cover was the most nerve racking part because if I didnt get it right, it was about 4+ to remove everything again, clean and reseal. There is a good video series on YT that explains everything from diagnosis to replacement.
