Misfire during hard turns?
The codes were secondary air injection codes. The shop thought the cause of those were a vacuum leak, unfortunately, got the car back yesterday and the CEL is back on again.
New tires are on the way to see about fixing the PSM (and when PSM is off, it seems ABS is kicking in early as well) issue.

I'm hopeful a correct sized set of tires will solve this for you, it certainly sounds like the solution based on your description of the issue and the condition of the tires. Fingers crossed!

that is ordinarily the FIRST place to eliminate as the cause, as it is normal, and most all of experimenting with tires have had some form of it.
do that first IF tires are mismatched in either tire tread depth/make, or both. as thats an instant recipe for cels on hard turns. gl.
My (new to me) Turbo feels like it is misfiring during normal driving, and has thrown a CEL, so I have been mostly babying it until I can get it into the shop this week...however, I noticed today that it seems to "misfire" or lose power much more prominently under semi-aggressive turning. Anyone ever heard of anything like this? Want to make sure I have some ideas when going In for service... Shawn
As an update, the issue was fixed by replacing the front tires with matching Nitto's. I'm very surprised by this, frankly, but lesson learned...all 4 tires need to be changed together!
cool you got it sorted
Makes sense, PSM and abs use wheel speed data to determine when to trigger, PSM in particular look at speed differences of all the wheels. Exceed that range and it can trigger, when you turn outside where's turn faster than inner and pushed you over the edge it seems. Glad it's fixed and that it was something useful like new tires
