Codes 14, 15, 16 & 17: Fuel Injector
NOTE:
Refer to illustration for ECU connector and terminal identification. See Figure
.
- Crank engine and ensure each fuel injector makes an operating sound. If fuel injectors make an operating sound, check fuel pressure. See BASIC TESTING article. If fuel injectors do not make an operating sound, go to next step.
- Turn ignition off. Disconnect connector from each injector. Turn ignition on. Measure voltage between each injector connector power supply terminal and ground. If voltage is not at least 10 volts, repair or replace harness connector. If voltage is at least 10 volts, check resistance between fuel injector terminals. If resistance is not 11-12 ohms, replace fuel injectors. If resistance is 11-12 ohms, go to next step.
- Disconnect ECU connector. Measure resistance between specified ECU connector E30 terminals and fuel injector terminal. See ECU CONNECTOR/FUEL INJECTOR TERMINAL IDENTIFICATION table. If less than 10 ohms are present on all terminals, repair ECU connector or replace ECU as necessary. If more than 10 ohms are present on any terminal, repair or replace harness or connector.
