3 codes at 990 miles

[Greendesert]

So, I have 3 codes and all seem pertaining to some electrical connectivity issue?
Taking to the dealer day after tomorrow.

I've gotten 3 check engine lights in 3 months, the first less than a month after I got it, they replaced an O2 sensor. Yesterday the light came in again, today they determined the heated O2 sensor needs to be replaced, but is on backorder with no ETA, so they told me it's safe to drive and gave it back until the part comes in

none of them are permanent codes, so they're probably normal or within tolerance.

this reminds me of a guy with some kind of obd2 gauge who was looking at a few misfires per drive and getting worried.

For a period back in the day, I designed and wrote predictive maintenance software for high end data storage cabinets (think tens of millions of dollars each), There's a fine line between ignoring transient (and meaningless) error codes and seeing patterns that predict future failure. FWIW, any complex system will generate thousands of spurious error codes. Sometimes daily. Sometimes hourly. Depends on the system, the sensors, the firmware coding.

My mantra, having seen how insanely complex it can be, is to leave the analysis to the engineers and data scientists programming the system. When I see a red light or the truck stops moving, then I'll pay attention. Beyond that, it's like making sausage - I don't want to see the process.

Not really, I got AWD error twice prompting to get service done. That is why I checked the codes.

That says 0 permanent codes at the top of screen.

That means the pending code has to be seen some number of times before it's determined this is an actual issue to actually set a DTC Because fluctuations in voltage, timing issues for communication, happen all the time.

I can go see my frequently reoccurring pending codes regarding same AC module, and couple other systems - but they are comm's issues, near startup, when everything is starting up and mass signaling going on.

If you got an actual DTC from that pending list - then that's the one that matters.

Today, I drove it and error c00a2 comes on within a minute. When stopped, error goes away. But comes right back when driving.

I hope they get these glitches resolved for you. I have around 1800 miles on my '25 without any issues. The truck has run flawlessly.

The dealer said a certain harness was not routed correctly at the factory and it sheared two wires.
Issue was fixed and no more codes or issues. Never heard something like this before.
