CHECKING THE INTAKE AIR PRESSURE
SENSOR
EWB03210
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.
1. Check:
• Intake air pressure sensor output voltage
Out of specification → Replace.

a. Connect the test harness S– pressure sensor
5S7 (3P) "1" between the intake air pressure
sensor and wire harness as shown.
b. Connect the digital circuit tester to the test
harness S– pressure sensor 5S7 (3P).
