Anyone get a P219A code?
Looking for advice on a solution to fix this recurring code. Sometimes it happens after 40 miles after being cleared, sometimes it takes 150 - 200 miles to reoccur. I notice no drop in performance, rougher idol, etc. Car has been checked for a vacuum leak - nothing. I do have a breather cap on the oil but have had it for much longer than I've had the code issue.
Google definition of code is: The Fuel Trim Cylinder Balance diagnostic detects a rich or lean cylinder to cylinder air/fuel ratio imbalance. The diagnostic monitors the heated oxygen sensor (HO2S) signal frequency and amplitude characteristics by calculating an accumulated voltage over a predetermined sample period. An imbalance is indicated when multiple samples of the accumulated voltage are consistently higher than the desired value.
Swapped the o2 sensors this weekend to see if code followed the sensor over to the other bank - no go, still left bank. Also have switched back and forth between aftermarket and stock tune. Get same code with either tune.
Any ideas?

So far, we have smoked the engine - no leaks and switched the O2 sensors side-to-side to see if the code followed the sensor. P219A is an imbalance in the left bank. Hoped that after the switch we would get an imbalance in the right bank (P219B) indicating it was the sensor but no such luck. Still left bank.

As for the other code I'm looking in to it as I'm not sure what that is.

I saw your post regarding which is bank 1 in the Tech section…with the P219A there are too many variables for the DIY’er mechanic to diagnose without specialized diagnostic equipment…suggest you seek out a diagnostic shop and NOT a general repair shop or a dealership as they WILL only throw parts at this and that will be expensive !!…this is not a blown fuse as many will hope it is.
