Also, if your truck has been sitting for a while, you might need to go drive a second, to “wake them up”.

Check out the following thread. Lots of discussion about Tire Pressures and how to do it with Modules. Only year mentioned that seemed to have issues was 2007. Your 2011 should work.

I did add them, before I added the gauge to the dashboard. I had driven it around while watching the display. Never got anything. I had an old ELM327 adapter and wired in a switch to allow HSCAN/MSCAN. I hooked it up and confirmed everything worked on HSCAN. Changed settings to 11-bit/125kbit and tried fetching the TPMS data. I got a CANBUS error. I'm going to put an oscilloscope on those pins tomorrow. I installed an iDatalink Maestro a couple of years ago but never touched the MSCAN wiring.You need to add the following...

Very impressed with the OBDLink app and all the PID's available. I've got my dashboards pretty much how I want them but I can't find engine oil temp. I've got the 2017 Expy PIDs installed and have looked thru most of the modules. Figured it would be in the powertrain module but don't see it. Any ideas?
There is no Oil Temp Sensor PID in PCM. Use the Engine Oil Temp SAE PID.

Loki, thanks man. I've looked in the SAE PID's but don't see it there either. There are several engine coolant temp PID's but no oil temp. I'll check again in the morning but I've looked in there a few times over the last week and I'm pretty sure it's missing from mine.
It's interesting that different modules seem to have similar or the same PID's. Like engine coolant temp, there are three of them in the PCM and I think two in the SAE. Different sensors?
And I'm also wondering if the battery saver function is operating correctly on mine. It seems to stay powered on for quite some time after the truck is shut down. I figured the auto power off would occur within twenty minutes or so.

Auto Power option watchs battery voltage, and it draws very little. I am sure it takes a while to get to a voltage to trigger power down.
Several of the Extended and SAE PIDs use the same sensors.
