INSPECTION
1. REMOVE IAT SENSOR
2. INSPECT IAT SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: Refer to the graph
If the resistance is not as specified, replace the sensor.

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.
SST 09816-30010
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

INSPECTION
1. INSPECT HEATER RESISTANCE OF MAIN HEATED
OXYGEN SENSOR (BANK 1 SENSOR 1)
(a) Disconnect the oxygen sensor connectors.
(b) Using an ohmmeter, measure the resistance between the
terminals +B and HT.
Resistance: 11 - 16 W at 20°C (68°F)
If the resistance is not as specified, replace the sensor.
Torque: 44 N´m (440 kgf´cm, 32 ft´lbf)
(c) Reconnect the oxygen sensor connectors.
2. INSPECT HEATER RESISTANCE OF SUB HEATED
OXYGEN SENSOR (BANK 1 SENSOR 2)
(a) Remove the passenger's seat.
(b) Take out the console box side of the floor carpet.
(c) Disconnect the oxygen sensor connector.
(d) Using an ohmmeter, measure the resistance between the
terminals +B and HT.
Resistance: 11 - 16 W at 20°C (68°F)
If the resistance is not as specified, replace the sensor.
Torque: 44 N´m (440 kgf´cm, 32 ft´lbf)
(e) Reconnect the oxygen sensor connectors.
(f) Reinstall the floor carpet.
(g) Reinstall the passenger's seat.
