Toyota Venza: Camshaft Position "B" Actuator Circuit / Open (Bank 1) (P0013)

Toyota Venza Service Manual / 1ar-fe Engine Control / Sfi System / Camshaft Position "B" Actuator Circuit / Open (Bank 1) (P0013)

DESCRIPTION

The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.

The camshaft timing oil control valve is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.


DTC No.

Trouble Area

P0013

Open or short in camshaft timing oil control valve (for exhaust camshaft) circuit

(1 trip detection logic)
  • Open or short in camshaft timing oil control valve assembly (for exhaust camshaft) circuit
  • Camshaft timing oil control valve assembly (for exhaust camshaft)
  • ECM

MONITOR DESCRIPTION

This DTC is designed to detect open or short in the camshaft timing oil control valve (for exhaust camshaft) circuit. If the camshaft timing oil control valve assembly's duty-cycle is excessively high or low while the ignition switch is ON or the engine is running, the ECM will illuminate the MIL and set the DTC.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch to ON and turn the Techstream on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) (See page ).

  4. Turn the ignition switch off and wait for at least 30 seconds.
  5. Turn the ignition switch to ON and turn the Techstream on.
  6. Wait 5 seconds.
  7. Enter the following menus: Powertrain / Engine / Trouble Codes.
  8. Read Pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  9. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  10. Input the DTC: P0013.
  11. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

    N/A
    • Unable to perform DTC judgment
    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    HINT:

    • If the judgment result shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system has a malfunction.
  12. If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (See page ).

    HINT:

    • If a permanent DTC is output, the system is malfunctioning.
    • If no permanent DTC is output, the system is normal.

CAUTION / NOTICE / HINT

HINT:

  • If DTC P0013 is output, check the VVT system (for exhaust camshaft) circuit.
  • Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

PROCEDURE

1.

PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE CAMSHAFT TIMING OIL CONTROL VALVE)

(a) Connect the Techstream to the DLC3.

(b) Start the engine.

(c) Turn the Techstream on.

(d) Turn the A/C switch on.

(e) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1).

(f) Check the engine speed while operating the camshaft timing oil control valve assembly (for exhaust camshaft) using the Techstream.

OK:

Techstream Operation

Specified Condition

0%

Normal engine speed

100%

Engine idles roughly or stalls

HINT:

If the result is not acceptable, cool the engine (engine coolant temperature is 50°C (122°F) or less) and perform the Active Test again.


OK

CHECK FOR INTERMITTENT PROBLEMS
