Variable Valve Timing Actuator Position Sensor: Testing and Inspection

COMPONENTS

INSPECTION
1. REMOVE V-BANK COVER

2. VVT Sensor (Bank 2):
REMOVE INTAKE AIR CONNECTOR PIPE

3. VVT Sensor (Bank 1):
DISCONNECT ENGINE WIRE PROTECTOR FROM UPPER INTAKE MANIFOLD AND BEARING CAP
a. Remove and disconnect these parts:
- No.2 V-bank cover bracket
- EVAP hose from VSV for EVAP
- VSV for EVAP from upper intake manifold
- No.3 V-bank cover bracket from upper intake manifold Accelerator cable and clamp
- PCV hose from upper intake manifold
- Air inlet hose for EVAP from air tube
b. Remove the 4 bolts, and disconnect the engine wire protector from the upper intake manifold and camshaft bearing cap.




4. INSPECT VVT SENSOR RESISTANCE

NOTE: "Cold" and "Hot in these sentences express the temperature of the sensors themselves. "Cold" is from -10 °C (14°F) to 50°C (122°F) and "Hot" is from 5OaC (122°F) to 100°C (212°F).

a. Disconnect the VVT sensor connectors.
b. Using a ohmmeter, measure the resistance between terminals.




Resistance:

If the resistance is not as specified, replace the sensor.

c. Reconnect the VVT sensor connectors.

5. VVT Sensor (Bank 1):
REINSTALL ENGINE WIRE PROTECTOR TO UPPER INTAKE MANIFOLD AND BEARING CAP

6. VVT Sensor (Bank 2):
REINSTALL INTAKE AIR CONNECTOR PIPE

7. REINSTALL V-BANK COVER
