With a test lead set, check for continuity
across sensor signal wire from pump discharge pressure transducer wire harness
connector, terminal 2, to pump discharge pressure transducer wire harness connector,
terminal C.
If continuity is not present, repair sensor ground wire in pump intake
pressure transducer wire harness if repairable (TM 9-2320-325-14&P), or
replace pressure transducer wire harness (WP 0460).
