4. Measure the Voltage Between Boost Pressure Sensor
Terminals
1. Set the key switch to the OFF position, and unplug the boost
pressure sensor connector from the socket.
2. Place the key switch in the ON position, and measure the
voltage between terminals (1) and (3) of the boost pressure
sensor connector (at the wiring harness side).

5. Measure the ECU Terminal Voltage
1. Move the key switch from the OFF to the ON position, and
measure the voltage between ECU terminals A-46 and A-57.
NOTE
• Check the hose between intake manifold and sensor, When
it is damaged, the boost pressure can not reach the sensor.
