DESCRIPTION

The Variable Valve Timing (VVT) system includes the ECM, OCV and VVT controller. The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller regulates the exhaust camshaft angle using oil pressure through the OCV. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual exhaust valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

INSPECTION PROCEDURE

HINT:
  1. If DTC P0013 is displayed, check the exhaust camshaft circuit for the bank 1 VVT system.
  2. Bank 1 refers to the bank that includes cylinder No. 1.
  3. If DTC P0023 is displayed, check the exhaust camshaft circuit for the bank 2 VVT system.
  4. Bank 2 refers to the bank that does not include cylinder No. 1.
  5. Read freeze frame data using an intelligent tester. 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 (RAV4_ACA30 RM000000PDS09FX.html).
1.PERFORM ACTIVE TEST USING INTELLIGENT TESTER (OPERATE OCV)

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine and turn the tester on.

  1. Warm up the engine.

  1. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the VVT System (Bank 1) or Control the VVT System (Bank 2).

  1. Check the engine speed while operating the Oil Control Valve (OCV) using the tester.

    OK:

    Tester Operation
    		Specified Condition
    OCV OFF
    		Normal engine speed
    OCV ON
    		Engine idles roughly or stalls (soon after OCV switched from OFF to ON)

  1. Disconnect the exhaust camshaft OCV connector.

  1. Measure the resistance between the terminals of the OCV.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C (68°F)
    		6.9 to 7.9 Ω

  1. Reconnect the OCV connector.
