Intake sensor ISUZU TROOPER 1998 Service Repair Manual

6J – 12 INDUCTION
INSPECTION AND RAPAIR
1. Visually check for cracks/clogs inside intake
manifold.
2. If foreign material is observed, it should be taken
out, and if there are some cracks on the intake
manifold, it must be replaced.
INSTALLATION
1. Install the intake manifold assembly, tighten bolts
and to the specified torque.
Torque: 20 N·m (2.0 kg·m / 14.5 lb ft) for bolt
Torque: 20 N·m (2.0 kg·m / 14.5 lb ft) for nut
2. Install fuel pipe.
Torque: 4 N·m (0.4 kg·m / 2.9 lb ft) for M16 nut
(Apply engine oil)
Torque: 13 N·m (1.3 kg·m / 9.4 lb ft) for M10 cap nut
Torque: 14 N·m (1.4 kg·m / 10 lb ft) for M10
(Apply engine oil)
3. Install two way check valve.
Torque: 20 N·m (2.0 kg·m / 14.5 lb ft)
4. Fill with about 300 cc of engine oil from the high
pressure oil pipe installation port of the oil rail using
an oil filler.
If assembled without filling the oil rail with oil, the
time for engine starting will be longer.
5. Install high pressure oil pipe, then tighten sleeve nut
to the specified torque.
Torque: 29 N·m (3.0 kg·m / 21.7 lb ft)
6. Reconnect harness connector to MAP sensor, EGR
vacuum sensor, ETC sensor, Water thermo unit,
IAT sensor and EVRV sensor.
7. Install hoses to EGR valve, EGR vacuum sensor
and Water outlet of heater.
8. Connect PCV hose.
9. Install oil level gauge guide and fix it.
10. Install intercooler assembly.
Refer to “Intercooler” in this manual.
11. Install water hose to thermostat housing and fill with
engine coolant.

8DÐ118 WIRING SYSTEM
QOS and EGR System (4JG2)
General Description
The circuit consists of the starter switch, QOS/EGR
control unit, glow relay, charge relay, fuel cut
solenoid, dropping resistor, thermo sensor, glow
indicator light (meter), glow plug, vehicle speed
sensor, tacho sensor, throttle position sensor, EVRV
and VSV; EGR.
The engine coolant temperature at the time of the
engine start-up is sensed by the thermo sensor to
change the glow time so that the optimum starting
conditions can always be obtained.
The idling speed just after the engine start-up can
also be placed in the most suitable conditions in
accordance with the coolant temperature by the
operation of the delay timer.The indicator timer is activated upon the starter
switch turned to the ON position, and the indicator
light comes on for as much time as suitable for the
engine coolant temperature at the time of the
engine start-up.
EGR system controls the information of NOx by
returning a small amount of exhaust gas from the
intake manifold to the combustion chamber
through the EGR valve.
