ON-VEHICLE INSPECTION
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.

Soon after OCV switched from OFF to ON, engine idles roughly or stalls |
(d) Inspect the oil control valve (for exhaust camshaft).
(1) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (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.

MONITOR DESCRIPTION
The ECM monitors the output voltage to the throttle actuator. This self-check
ensures that the ECM is functioning properly. The output voltage is usually 0 V
when the ignition switch is turned off. If the output voltage is higher than ...

HINT:
Using the Techstream to perform Active Tests allows relays, VSVs, actuators and
other items to be operated without removing any parts. This non-intrusive functional
inspection can be very useful because inter ...
