Engine/Transmission (1998.5 - 2002) Truck gave me a birthday present, PO237 and PO112

[Stranger]

Started the truck and headed out on errands. About 40mph, it shuddered a bit, just a thunk. Kinda like the tires slipped on a bit of ice. It's almost 90 outside so, that wasn't it.



SEL came on, ran fine and normal. Checked codes with a OBDII scanner and it coughed up a PO237 and a PO112, then repeated codes.



Truck is stock, Lift pump replaced in Sep. 2005, under warranty, VP44 was replaced in 2006 also under warranty, have put about 26K on it.



Is this a serious issue?



Thanks in advance,

Bill

Thanks, Rusty.
Unfortunately, I don't have the DRB111 scanner.

Unplug both of them and clean both conns with electronic cleaner (sensor and harness) might clear it up
