http://www.obd-codes.com/p0606........http://www.obd-codes.com/p0012.....Looks like your going to need to replace the PCM. P0012 might disappear if you do. So work on P0606 first. .

There is a recall on the PCM aka ECU for the 2008 Corolla: Recall ID # 81862 - ENGINE AND ENGINE COOLING Recall Date: AUG 26, 2010 Model Affected: 2008 Toyota Corolla Summary: TOYOTA IS RECALLING CERTAIN MODEL YEAR 2005-2008 COROLLA AND COROLLA MATRIX VEHICLES. THE ENGINE CONTROL MODULE (ECM) FOR THE SUBJECT MODELS EQUIPPED WITH THE 1ZZ-FE ENGINE AND TWO-WHEEL DRIVE MAY HAVE BEEN IMPROPERLY MANUFACTURED. THERE IS A POSSIBILITY THAT A CRACK MAY DEVELOP AT CERTAIN SOLDER POINTS OR ON VARISTORS ON THE CIRCUIT BOARD. Consequences: THERE ARE A VARIETY OF WARNINGS AND CONSEQUENCES ASSOCIATED WITH THE DEFECT. THE ENGINE WARNING LAMP COULD BE ILLUMINATED, HARSH SHIFTING COULD RESULT, THE ENGINE MAY NOT START, OR THE ENGINE COULD SHUT OFF WHILE THE VEHICLE IS BEING DRIVEN.

From http://engine-codes.com/p0606_toyota.html P0606 Toyota - ECM Processor Error Possible causes - Faulty Engine Control Module (ECM) - Engine Control Module (ECM) Harness power supply circuit is open or shorted - Engine Control Module (ECM) Programming

P0012 Toyota - Camshaft Position Timing Over-Retarded Possible causes - Dirty or low engine oil - Damaged ECM

All that my point being Tom has it right on.
