3. Disconnect the vacuum hose.
4. Disconnect the circlip and remove the fuel pressure
regulator.
5. Apply the oil to O-ring lightly and then replace it.
6. Installation should follow the removal procedure in the
reverse order.
7. Check for fuel pressure and internal leaks by operating the
engine. 2. Discharge the pressure in fuel supply system by pressing
the service valve.
Removal & Installation Procedure
1. Remove the fuel pressure test connector.

M162 ENGINE CONTROLS 1F1-55
Removal & Installation Procedure
1. Remove the O-ring.
Check for damage and replace it if necessary.
2. Remove the injector bracket from the injector.
Installation Notice
Exactly seat the anti-twist lock into the square groove in
injector.
3. Separate the injector from the fuel distributor.
Inspection & Maintenance
Inspection of the Injector operation and spray pattern
1. Connect the contact box to the ECU.
2. Connect the shop made test plug to the injector and place
it into the tank.
3. Position the ignition switch to ON.
4. Connect the pin 63(+) and 69(-) of the contact box with a
test cable.
5. Check the injector spray pattern.
Notice
Replace the injector if the injector spray pattern is abnormal
or the fuel doesn't inject.
Injector Resistance Inspection
1. Remove the injector connector.
2. Measure the injector coil resistance using a resistance
tester.
Notice
Replace the injector if the measured values is out of the
specified values. Check the connector and wire connection
between the ECU and the injector if the measured values
are normal.
Specified Value
14 - 17 W

6 Heating Coil
7 Open Space
8 Protector Tube
Functions
The oxygen sensor optimizes the combustion (Air-Fuel Ratio
14.7:1) and resets the Air-fuel ratio in the ECU after sensing
the amount of oxygen from the exhaust gases to diminish the
exhaust gases.
- Rich(<1) above approx. 450mV
- Lean(>1) below approx. 450mV
Locatoin of Sensor
Oxygen sensor is located on the front exhaust pipe.
