Q: Engine Code: Injector Circuit Cylinder 4 Intermittent on 1997 Dodge Grand Caravan

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Got engine code P1231 on my '97 grand caravan;
Injector Circuit Cylinder 4 Intermittent.
Any idea what this means and could it be related to the recall on leaking O rings?
(1) Answer
An injector circuit code is an electrical fault. The P1231 is a manufacturer code. The problem is either in the injector, the wiring or the injector driver inside the computer. If you can get a labscope pattern of the injector, you could see which one of these options is the culprit. Any good shop should be able to scope your injector for 1/2 hour of labor.
