DTC 16

DIAGNOSIS:
- The fuel injector is not in function.
- The harness connector between ECM and each fuel injection is in short or open.

TROUBLE SYMPTOM:
- Engine stalls.
- Erroneous idling
- Rough driving

1. CHECK OPERATION OF EACH FUEL INJECTOR.
While cranking the engine, check that each fuel injector emits "operating" sound. Use a sound scope or attach a screwdriver to injector for this check.




2. CHECK POWER SUPPLY TO FUEL INJECTOR.
1. Turn ignition switch to OFF.
2. Disconnect connector from each injector.
3. Turn ignition switch to ON.
4. Measure voltage between each injector connector terminal and body.

Connector & terminal / Specified voltage:
#1 (E7) No.2 - Body / 10 V, min.
#2 (E17) No.2 - Body / 10 V, min.
#3 (E8) No.2 - Body / 10 V, min.
#4 (E18) No.2 - Body / 10 V, min.




3. CHECK EACH FUEL INJECTOR.
Measure resistance between fuel injector terminals.

Terminals / Specified resistance:
No.1 - No.2 / 11 - 12 Ohm




4. CHECK HARNESS CONNECTOR BETWEEN ECM AND EACH FUEL INJECTOR.
1. Disconnect connector from ECM.
2. Measure resistance of harness connector between ECM connector and each fuel injector.

Connector & terminal / Specified resistance:
(E30) No.2 - (E7) No.1 / 10 Ohm, max.
(E30) No.1 - (E17) No.1 / 10 Ohm, max.
(E30) No.13 - (E8) No.1 / 10 Ohm, max.
(E30) No.12 - (E18) No.1 / 10 Ohm, max.
