DIAGNOSIS CODE PROCEDURES

Code No. P0010: Inlet Oil Feeder Control Valve System

OPERATION

• Power is supplied to the inlet oil feeder control 

valve connector terminal from the engine control 
relay connector terminal.

• The engine-ECU connector terminal OCVI makes 

the power transistor in the unit be in ON position, 
and that makes currents go on the inlet oil feeder 
control valve connector terminal.
