Variable Valve Timing Actuator Position Sensor: Testing and Inspection

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

NOTICE: "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).

(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
