Turbo Boost Sensor: Testing and Inspection

INSPECTION OF TURBOCHARGING PRESSURE SENSOR





1. INSPECT POWER SOURCE VOLTAGE OF TURBOCHARGING PRESSURE SENSOR
(a) Turn the ignition switch ON.
(b) Using a voltmeter, measure the voltage between terminals VC and E2.

Voltage: 4 - 6 V





2. INSPECT POWER OUTPUT OF TURBOCHARGING PRESSURE SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the vacuum hose of the intake manifold (chamber) side.
(c) Connect a voltmeter to terminals PIM and E2 of the pressure sensor, and measure and record the output voltage under ambient atmospheric pressure.
(d) Apply vacuum to the pressure sensor in 100 mmHg (3.94 in.Hg, 13.3 kPa) segments to 500 mmHg (19.69 in.Hg, 66.7 kPa).




(e) Measure voltage drop from step (c) above for each segment.
