Variable Valve Timing Actuator Position Sensor: Testing and Inspection
INSPECTION / VVT Sensor1. 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 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:
- cold 835-1,400 Ohms
- Hot 1,060 - 1645 Ohms
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
