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).

Disconnect the VVT sensor connectors.

Using a ohmmeter, measure the resistance between terminals.

Resistance:

VVT SENSOR RESISTANCE SPECIFICATION

Cold	835 - 1,400 Ω
Hot	1,060 - 1,645 Ω

Fig 1: Measuring Resistance Between VVT Sensor Terminals

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

Reconnect the VVT sensor connectors.
