Was i just low on oil? What do those really mean in the 6.5? I hot stalled on starting up - i added oil which was low a quart. Started right up. Gonna put in my lube specialist lines and my own bypass dual oil filter lines from summit. Been leaking 2 qts a day from a hole in the oil cooler intake...

Those are injection pump codes. Could be as simple as a loose connection on top of the pump. My dealer just replaced my pump (under warranty) with those two codes showing up. By the way, the "Member's Area" of this site has a list of all DTC'S.

yes. I read it. Thanks.

let me clarify: Could the OPS not running cause those codes, or should i prepare to hunt down the wiring harnesses to check?
