Check your engine oil level, low engine oil will cause that trouble code. Also check your valve timing solenoid, try cleaning the solenoid and the filter. Clear the code and see if that takes care of it, if not your VTEC oil pressure switch may have failed. It could also be a faulty oil pressure switch sending incorrect information to the ECM/PCM
