I just had the same thing happen with my car. Codes were P2626 (O2 sensor pumping current trim/open bank), P0392 (camshaft position sensor B circuit low input), P0368 (camshaft position sensor B Circuit high input), P0027 (crankshaft position correlation). Car was running but not optimally. Scheduled a appointment and order some camshaft position sensors which are arriving today. Yesterday, code cleared on its own, and car is running great.

My wild guess is that the car retarded timing as a result of bad gas, and after that cleared the system, and the car ran fine with all the pep it had before. I'm going to wait to see if it reappears and have the sensors ready for replacement.

Edit -- For those so interested, the retail price on these sensors is around $170, they can be generally bought for $120-140, but if you buy from AutohausAZ, they are $60.
