1. INSPECT POWER SOURCE VOLTAGE OF MAP SEN-
SOR
(a) Disconnect the MAP sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminals VC and E2 of the wiring harness side.
Voltage: 4.5 ± 5.5 V
(d) Turn the ignition switch OFF.
(e) Reconnect the MAP sensor connector.
2. INSPECT POWER OUTPUT OF MAP SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the vacuum hose from the MAP sensor.
(c) Connect a voltmeter to terminals PIM and E2 of the ECM,
and measure the output voltage under ambient atmo-
spheric pressure.
(d) Apply vacuum to the MAP sensor in 13.3 kPa (100 mmHg,
3.94 in.Hg) segments to 66.7 kPa (500 mmHg, 19.69
in.Hg).
(e) Measure the voltage drop from step (c) above for each
segment.
(f) Turn the ignition switch OFF.
(g) Reconnect the vacuum hose to the MAP sensor.

2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Disconnect the vacuum hose from the vapor pressure
sensor.
(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
(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
2, 0.22 psi)) to the
vapor pressure sensor.
Voltage: 4.2 ± 4.8 V
(d) Turn the ignition switch OFF.
(e) Reconnect the vacuum hose to the vapor pressure sen-
sor.
