Clear diagnostic trouble codes (DTC) and re-check DTCs. Does DTC follow delivery pressure sensor? YES: Pump 1 delivery pressure sensor malfunction. Replace sensor. NO: Go to Sensor Circuit Check.
– – –1/1 2 Sensor Circuit Check Disconnect connector to pump 1 delivery pressure sensor. Check voltage between terminals 1 and 3 of harness. Is voltage between 4.5—5.5 volts? NOTE: Key Switch: ON YES: Go to Open Circuit Check. NO: Go to Harness Voltage Check. – – –1/1 3 Open Circuit Check Disconnect connector to pump 1 delivery pressure sensor. Check continuity between main controller (MCF) connector C pin C3 and pump 1 delivery pressure sensor pin 2. Is there continuity between the pins? YES: Go to Short Circuit Check. NO: Open in harness. Repair or replace harness. See Cab Harness (W1) Wiring Diagram, see Machine Harness (W2) Wiring Diagram, and see Pump Harness (W8) Wiring Diagram.
