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 to 2.1 V
2. Release the vacuum from the vapor pressure sensor.
Voltage: 3.0 to 3.6 V
3. Apply pressure (1.5 kPa (15 gf/cm
2
, 0.22 psi)) to the vapor pressure sensor.
Voltage: 4.2 to 4.8 V
d. Turn the ignition switch OFF.
