As far as P119F/P219A, I've not looked at anything on the car. If I do anything about it it'll be bypassing the whole diagnostic chart and going straight for the valve shims. But I'm not there yet.
The Toyota dealership themselves have done NO diagnostic, after a ridiculous fumbling start, they've punched the DTCs into their system and apparently toronto was like "Don't touch it wait for TSB", or something to that matter, without seeing the actual message on the screen, I'm keeping my grain of salt handy, but if true, that's actually reassuring because IF they're told to wait for updated procedures, it could be assumed that they'll execute those procedures once they are told to, rather than keep the car for two weeks and throw parts at it that would have taken less than an hour like they did for datty up there.
As for what is published, that's where things get weird. I use Mitchell ProDemand at work and there is nothing published for those codes under Toyota, no TSB either. It's a different case when looking for a Subaru BRZ. Even Toyota's TIS service is ambiguous. I subscribed for 3 days and the codes were documented and reflected the up-to-date information from Subaru. I've still got the printout and back then, the current version was dated 06-08-2018. But when I recently went to a different dealership (where I actually bought it) for a window scratching on the guides, I asked them if they could look up any info on those faults, and what they printed from their TIS login did NOT reflect the up-to-date procedure, their documentation did NOT instruct to check valve lash. BTW, the rip of the TIS website in your signature is NOT up-to-date either.
long story short, it's a biiiiiiiiig clustertruck.
But I think my outlook on this situation is kind of skewed: I've got access to diagnostic information services, I've worked with extended warranties so I understand that you can't just tear into something willy nilly before getting the OK from higher up, I've seen how the diagnostic info seems to be all over the place, probably through the fault of no one specific person and ultimately, I know that if I get pissed off about it, I can sort it out myself in a weekend.
So I'm rather mellow about all of it.
