CHECKING THE INTAKE AIR PRESSURE
SENSOR
1. Remove:
• Intake air pressure sensor
(from the throttle bodies)

WARNING
• Handle the intake air pressure sensor with
special care.
• Never subject the intake air pressure sen-
sor to strong shocks. If the intake air pres-
sure sensor is dropped, replace it.
2. Check:
• Intake air pressure sensor output voltage
Out of specification → Replace.
