This code indicates the engine control module has detected an electrical irregularity within the circuit monitoring the metering oil pump position. The metering oil pump is responsible for injecting lubricating oil into the engine intake or fuel system to maintain internal lubrication. When this circuit malfunctions, the system cannot verify proper oil delivery rates or pump positioning.
Internal electrical failure within the sensor prevents accurate position reporting to the control module.
Heat or oil exposure near the pump causes shorts or open circuits in the wiring connecting the sensor.
Physical obstruction or wear prevents the pump from moving to the commanded position.
Power supply interruption stops the pump circuit from functioning correctly.
Corrosion or looseness at the ground point disrupts sensor voltage signals.
Internal processor error is rare and should only be considered after all other components are verified.
No, continued driving risks severe engine damage due to insufficient internal lubrication.
No, PCM failure is rare and the sensor or wiring is the usual cause.
No, the underlying electrical or mechanical fault will cause the code to return.
Yes, an empty reservoir can prevent the pump from operating within expected parameters.
