E21 Mass air flow sensor signal circuit malfunction
E22 Engine Coolant temperature signal circuit malfunction
E23 Throttle Postion sensor signal circuit malfunction
E30 ECM System Malfunction
P03 VCM Communication Error

Sounds like maybe someone was troubleshooting while truck was running and unplugging sensors??

First thing i would check is the battery and make sure it is in good health and check the alternator belt and make sure its tight??

Is unusual to have this many codes pop up all at once??
