INSPECTION
1. REMOVE LUGGAGE COMPARTMENT BOX
2. REMOVE FLOOR SERVICE HOLE COVER
3. REMOVE VAPOR PRESSURE SENSOR
a. Remove the 2 bolts and No.3 fuel tank protector.
b. Disconnect the vapor pressure sensor connector.
c. Remove the clip and vapor pressure sensor.
4. INSPECT VAPOR PRESSURE SENSOR
a. Turn the ignition switch ON.
b. Using a voltmeter, measure the voltage between connector terminals VC and E2 of the wiring harness side.
Voltage: 4.5 - 5.5 V
c. Turn the ignition switch OFF.
5. INSPECT POWER OUTPUT OF VAPOR PRESSURE SENSOR
a. Connect the vapor pressure sensor connector.
b. Turn the ignition switch ON.
c. Connect a voltmeter to terminals PTNK and E2 of the ECM, and measure the output voltage under the following conditions:
1. Apply vacuum (2.0 kPa (15 mmHg, 0.59 in.Hg)) to the vapor pressure sensor.
Voltage: 1.3 - 2.1 V
