Using FOR SCAN, keep getting DTC P0232, High voltage fuel pump secondary circuit.

Truck runs fine, replaced the fuel pump and FP relay about 9 months ago.... Any ideas?

Thanks

Mike

Are you getting P0203 as the title says or P0232 as you indicate in the body of the text?

Most likely it is P0232, so below and attached is some information and the pinpoint test.




See attachment for pinpoint test.
