Code No. P0010: Inlet Oil Feeder Control Valve System
 
 
 
 
OPERATION
  • Power is supplied to the inlet oil feeder control valve from the engine control relay.
  • 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.
 
 
FUNCTION
  • The engine-ECU controls the spool valve position of the inlet oil feeder control valve corresponding to the driving condition of the engine and continuously changes the angle of the inlet camshaft.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Ignition switch is "ON" position.
  • Battery positive voltage is more than 10 V and is less than 16.5 V.
Judgement Criterion
  • The engine-ECU terminal current value of inlet oil feeder control valve circuit is less than 0.1 A for 2 seconds.
Check Conditions
  • Ignition switch is "ON" position.
  • Battery positive voltage is more than 10 V and is less than 16.5 V.
  • ON duty cycle of the inlet oil feeder control valve circuit is more than 20 %.
Judgement Criterion
  • The engine-ECU terminal current value of inlet oil feeder control valve circuit is more than 2.9 A.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • V.V.T. phase angle (inlet) becomes most retarded angle.
 
 
PROBABLE CAUSES
  • Failed inlet oil feeder control valve
  • Open/short circuit or harness damage in inlet oil feeder control valve circuit or loose connector contact
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check inlet oil feeder control valve itself.
  • Inlet oil feeder control valve check (Refer to ).
Is the check result normal?
Go to Step 2.
Replace the inlet oil feeder control valve.
 
STEP 2. Perform voltage measurement at inlet oil feeder control valve connector.
  • Disconnect connector, and measure at harness side.
  • Ignition switch: ON
  • Voltage between terminal engine-ECU OCVI line and body earth.
OK: System voltage
Is the check result normal?
Go to Step 3.
Repair the connector(s), or check and repair of short to earth, and open circuit in OCVI line between engine control relay connector and inlet oil feeder control valve connector.
 
STEP 3. Perform voltage measurement at engine-ECU connector.
  • Disconnect connector, and measure at harness side.
  • Ignition switch: ON
  • Voltage between terminal OCVI and body earth.
OK: System voltage
Is the check result normal?
Go to Step 4.
Repair the connector(s), or check and repair of short to earth, and open circuit in OCVI line between inlet oil feeder control valve connector and engine-ECU connector.
 
STEP 4. Check of damage in power supply line between engine control relay connector and inlet oil feeder control valve connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. Check of damage in OCVI line between inlet oil feeder control valve connector and engine-ECU connector.
Is the check result normal?
Go to Step 6.
Repair the connector(s) or wiring harness.
 
STEP 6. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the engine-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
