Machine Sluggish / Lugging
Variant 1
System
Hydraulic
Symptom
Machine Sluggish / Lugging
Diagnosis & fix steps
LOGIC: Pump #1 Outlet Pressure Sensor Not Responding.
ACTION: Swap sensors between Pump 1 & 2. If code moves, replace sensor.
Red Seal field insights
PRO-TIP: A -7 FMI often means the sensor is "stuck" at a specific voltage and isn't fluctuating with load.
Variant 2
System
Hydraulic
Symptom
Slow Hydraulic Cycle Times
Diagnosis & fix steps
LOGIC: Hydraulic Pump #1 Outlet Pressure Sensor: Not Responding Properly.
ACTION: Swap pump #1 and pump #2 sensor connectors. If the fault moves, replace the pressure transducer.
Red Seal field insights
Diagnostic Logic: FMI 7 means the mechanical response doesn't match the electrical command. The ECM sees a mechanical mismatch.
Variant 3
System
Hydraulic
Symptom
Pump #1 Outlet Pressure Sensor: Not Responding
Diagnosis & fix steps
LOGIC: Mechanical pressure exists but sensor signal is static.
ACTION: Swap Sensor #1 and #2. If fault follows sensor, replace it.
Red Seal field insights
Logic: The ECM sees pump swashplate movement but no corresponding pressure rise.
