– VAPOR PRESSURE SENSOR
INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
Disconnect the vapor pressure sensor connector.
Turn the ignition switch ON.
Using a voltmeter, measure the voltage between connec-
tor terminals VC and E2 of the wiring harness side.
Voltage: 4.5 – 5.5 V
Turn the ignition switch OFF.
Reconnect the vapor pressure sensor connector.
INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
Turn the ignition switch ON.
Disconnect the vacuum hose from the vapor pressure
sensor.
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
(2) Release the vacuum from the vapor pressure sen-
sor.
Voltage: 3.0 – 3.6 V
(3) Apply pressure (1.5 kPa (15 gf/cm
vapor pressure sensor.
Voltage: 4.2 – 4.8 V
Turn the ignition switch OFF.
Reconnect the vacuum hose to the vapor pressure sen-
sor.
