Injector #1 Control Circuit
WARNING: This page is about a different car, the 1995 Dodge Stratus, 1995 Dodge Avenger, 1995 Chrysler Sebring, and 1995 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS - 2.5L V6
article in ENGINE PERFORMANCE.
NOTE:
It may be necessary to remove intake plenum when performing this procedure.
- Reconnect injector harness connector. Remove intake plenum to access injector No. 1 connector. Disconnect injector No. 1 connector. Turn ignition on. Using scan tool, actuate Auto Shutdown (ASD) relay. Place scan tool in voltmeter mode.
- Using scan tool, check voltage of injector No. 1 connector Black/Red wire (FJ22 body) or Dark Green/Orange wire (JA body). If voltage is less than 10 volts, repair open in appropriate wire. Perform TEST VER-2 . If voltage is more than 10 volts, go to next step.
- Turn ignition off. Disconnect 10-pin (FJ22 body) or 4-pin (JA body) injector harness connector. See Fig 1 or Fig 2. On FJ22 body, using an external ohmmeter, check resistance of Light Green/Black wire between 10-pin injector harness connector (injector side) and injector No. 1 connector. On JA body, using an external ohmmeter, check resistance of White/Light Blue wire between 4-pin injector harness connector (injector side) and injector No. 1 connector.
- On all models, if resistance is less than 5 ohms, replace injector. Perform TEST VER-2 . If resistance is more than 5 ohms, repair open in appropriate wire. Perform TEST VER-2.
