Component InspectionEBS01211
CHECK TURBOCHARGER BOOST SENSOR
1. Remove turbocharger boost sensor with its harness connected.
2. Turn ignition switch ON.
3. Use pump to apply pressure sensor as shown in the figure.
CAUTION:

Always calibrate the pressure pump gauge when using it.

Inspection should be done at room temperature [10-30°C (50-86°F)].
4. Check the output voltage between turbocharger boost sensor terminal 2 and ground.

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
