Light came on about 4 hours after doing an oil change on the way home from dinner. Upon visual inspection all the sensors are connected. Though there is a crack in the intake pipe before the throttle body, ordering a replacement for that now. Could any of you guys point me in the right direction, having my friend with a multimeter come over in a few and check the related sensors.

 

plastic restrictor for the VVL intake lifters is broken, bolt is usually missing too. upper timing covers have to come off
