Variable Induction Position Sensor: Testing and Inspection

VARIABLE TUMBLE SHUTTER VALVE SWITCH INSPECTION[L3]

NOTE: Perform the following inspection only when directed.

Voltage Inspection
1. Turn the ignition switch to ON position (Engine OFF).

Variable Tumble Shutter Valve Switch Output Voltage:

2. Verify that the PCM terminal 2AE voltage is as shown in the table when the Variable tumble shutter valve actuator rod is depressed and released by hand.
- If not as specified, perform the "Circuit Open/Short Inspection".
- If there is no open or short circuit, replace the intake manifold.

Circuit Open/Short Inspection




1. Disconnect the PCM connector.
2. Inspect the following harnesses for open or short circuit. (Continuity inspection)

Open circuit
- If there is no continuity, there is an open circuit. Repair or replace the harness.
- Variable tumble shutter valve switch terminal A and PCM terminal 2AU
- Variable tumble shutter valve switch terminal B and PCM terminal 2AY
- Variable tumble shutter valve switch terminal C and PCM terminal 2AE

Short circuit
- If there is continuity, there is a short circuit. Repair or replace the harness.
- Variable tumble shutter valve switch terminal A and power supply
- Variable tumble shutter valve switch terminal A and body GND
- Variable tumble shutter valve switch terminal B and power supply
- Variable tumble shutter valve switch terminal C and power supply
- Variable tumble shutter valve switch terminal C and body GND
