Oxygen Sensor Signal Voltage Inspection
1. Maintain the engine speed is at idle while the coolant temperature is over 80°C.
2. Measure the oxygen sensor signal voltage between the ECM terminal No. 16 and No. 17.
Specified Value
-- 0.2 ~ 1.0 v
Notice:If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor or
ECM
Oxygen Sensor Heating Voltage Inspection
1. Maintain the engine speed is at idle while the coolant temperature is over 80°C.
2. Measure the oxygen sensor signal voltage between the ECM terminal No. 11 and No. 9.
Specified Value
11 ~ 14 v
Notice:If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor or
ECM
Oxygen sensor Heating Current Consumption Inspection
1. Turn the ignition switch to “ON” position.
2. Measure the oxygen sensor heating current consumption between the ECM terminal No. 9 and No. 5.
Specified Value
0.2~2.0A
Notice:If the measured value is not within the specified value, the possible cause may be in cable, oxygen sensor or
ECM

Notice:Before removal, the fuel rail assembly may be
cleaned with a spray-type cleaner, following package in-
structions. Do not immerse the fuel rails in liquid clean-
ing solvent. Use care in removing the fuel rail assembly
to prevent damage to the electrical connectors and in-
jector spray tips. Prevent dirt and other contaminants
from entering open lines and passages. Fittings should
be capped and holes plugged during service.
Important:If an injector becomes separated from the
rail and remains in the cylinder head, replace the injector
O-ring seals and the retaining clip.
12. Remove the injectors and the fuel rail carefully.
13. Remove the fuel injector retainer clips.
14. Remove the fuel injectors by pulling them down and
out.
15. Discard the fuel injector O-rings.
16. Lubricate the new fuel injector O-rings with engine
oil. Install the new O-rings on the fuel injectors.
17. Perform a leak check of the fuel rail and fuel injec-
tors.
18. Installation should follow the removal procedure in
the reverse order.

Removal and Installation Procedure
1. Relieve the coolant system pressure.
2. Disconnect the negative battery cable.
3. Disconnect the engine coolant temperature sensor
connector.
Notice:Take care when handling the engine coolant
temperature sensor. Damage to the sensor will affect
the proper operation of the fuel injection system.
4. Remove the engine coolant temperature sensor
from the pump hosing.
Installation Notice
Tightening Torque

Leakage Test
1. Warm the engine up to normal operating tempera-
ture.
2. Disconnect the negative battery cable.
3. Remove the spark plugs.
4. Check the coolant level by opening the coolant
surge tank cap and replenish if insufficient.
5. Open the engine oil filler cap.
6. Connect the tester to air pressure line and adjust the
scale of tester.
7. Install the connecting hose to spark plug hole.

8. Position the piston of No.1 cylinder at TDC by rotat-
ing the crankshaft.
9. Connect the connecting hose to tester and measure
the leakage volume after blowing up compressed
air.
Notice:Measure the leakage volume in the completely
opening condition of throttle valve by pulling the accel-
eration cable.
10. Perform the pressure test according to the firing or-
der.
Notice:Firing Order : 1 -- 3 -- 4 -- 2
11. Compare the leakage pressure with the specifica-
tions.
