VVT Sensor: Inspection

REMOVE V-BANK COVER
VVT Sensor (Bank 2): REMOVE INTAKE AIR CONNECTOR PIPE
VVT Sensor (Bank 1): DISCONNECT ENGINE WIRE PROTECTOR FROM UPPER INTAKE MANIFOLD AND BEARING CAP
1. Remove the No. 3 V-bank cover bracket.
2. Disconnect the EVAP hose from VSV for EVAP.
3. Remove the VSV for EVAP from upper intake manifold.
4. Remove the No. 2 V-bank cover bracket from upper intake manifold.
5. Disconnect the PCV hose from upper intake manifold.
6. Remove the 4 bolts, and disconnect the engine wire protector from the upper intake manifold and camshaft bearing cap.
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 50°C (122°F) to 100°C (212°F).
1. Disconnect the VVT sensor connectors.
2. Using a ohmmeter, measure the resistance between terminals.
