When I was test driving the truck, only on high rpm the code ICP above desired level appears and the truck derates power and staggers. check engine light does not appear on dash. I have a maxxforce program with usblink2. When running the test I i receive a code DTC 3373 SPN 164 FMI 15 ICP too high during test
