INSPECTION
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 to LOCK.
(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) Reconnect the vacuum hose to the MAP sensor.

INSPECTION
1. REMOVE KNOCK SENSOR
(a) Disconnect the knock sensor connector.
(b) Using SST, remove the knock sensor.

2. INSPECT KNOCK SENSOR
Using an ohmmeter, check that there is no continuity between
the terminal and body.
If there is continuity, replace the sensor.
3. REINSTALL KNOCK SENSOR
