INSPECTION
1. REMOVE EGR GAS TEMPERATURE SENSOR
2. INSPECT EGR GAS TEMPERATURE SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance:
At 50°C (122°F)64 - 97 kW
At 100°C (212°F)11 - 16 kW
At 150°C (302°F)2 - 4 kW
If the resistance is not as specified, replace the sensor.
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
3. REINSTALL EGR GAS TEMPERATURE SENSOR

(e) Connect a voltmeter to terminals PIM and E2 of the ECM,
and measure the output voltage under ambient atmo-
spheric pressure.
(f) Apply vacuum to the turbo pressure sensor in 13.3 kPa
(100 mmHg, 3.94 in.Hg) segments to 66.7 kPa (500
mmHg, 19.69 in.Hg).
(g) Measure the voltage drop from step (c) above for each
segment.

(h) Remove the SST.
SST 09990-01000
(i) Reinstall the ECM. (See page SF-86)
(j) Reconnect the vacuum hose to the turbo pressure sen-
sor.

OXYGEN SENSOR (BANK 1 SENSOR 2)
(a) Remove the driver'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: 20 N´m (200 kgf´cm, 14 ft´lbf)
(e) Reconnect the oxygen sensor connector.

INSPECTION
1. DISCONNECT NEGATIVE (-) TERMINAL CABLE
FROM BATTERY
2. REMOVE SCUFF PLATE
3. REMOVE ECM PROTECTOR
(a) Take out the front side of the floor carpet.
(b) Remove the 2 nuts and ECM protector.
4. REMOVE ECM
(a) Remove the nut, and disconnect the ECM from the floor
panel.
(b) Fully loosen the bolt and disconnect the 2 ECM connec-
tors, and remove the ECM.
5. INSPECT ECM
(See page DI-164)
6. REINSTALL ECM
(a) Connect the 2 ECM connectors.

Match the male connector correctly with the female
connector, then press them together.

Tighten the bolt.
Make sure the connector is completely connected
by tightening the bolt until there is a clearance of
less than 1 mm (0.04 in.) between the bottom of the
male connector and the end of the female connec-
tor.
(b) Install the ECM with the nut.
