CHECK CHARGE AIR PRESSURE SENSOR

1. Remove charge air pressure sensor with its harness connector connected.
2. Turn ignition switch “ON”.
3. Use pump to apply pressure to charge air pressure sensor as shown in the figure.

CAUTION:

I

Always calibrate the pressure pump gauge when using it.

I

Inspection should be done at room temperature [10 - 30°C (50 - 86°F)].

4. Check the output voltage between charge air pressure sensor terminal 2 and engine ground.
