PROCEDURE
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
(a) Connect the Techstream to the DLC3.
(b) Start the engine and turn the Techstream on.
(c) Inspect the oil control valve (for intake camshaft).
(1) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT System (Bank 1).
(2) Check the engine speed when the oil control valve is operated using the Techstream with the engine coolant temperature at 50°C (122°F) or less.
