Fault codes = need help
 

OK guys... could use some help here.

I have re-done my entire cold air return system for the emissions system on my 99 Box. Believe me... I was super careful in doing the job right and used all new parts and took my time to do things correctly. Granted the battery was disconnected for awhile (searched forums to see that may have caused one of my faults...). Also, I have noticed multiple tiny cracks in the gas cap sealing o-ring. My AOS has very few miles on it (less than 5K), Throttle body is clean (in fact new and increased in size from Pedro my man). Also just got done with putting in new water pump and new lower temp thermostat from LN too (not sure if any of this has to do with the CEL...)

Now after 250 to 300 miles after completing the work I got the CEL light.

Came up with these two codes...

P1602 fault code 660 CAN timeout instrument cluster

P 0446 fault code 95 shutoff valve acivated

Any ideas?

Thanks in advance for your help!
