Cylinder 2 Injector Circuit Low
There's a low voltage problem in the injector circuit for cylinder 2.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The injector for cylinder 2 isn’t getting enough voltage to open properly, which means that cylinder isn't getting the right amount of fuel.
What the computer is actually seeing
The Engine Control Module (ECM) sees a voltage drop below the expected threshold for the injector circuit when it should be around 12-14 volts during operation.
What a healthy reading looks like
Injector voltage should be between 12 to 14 volts when the engine is running; resistance in the injector circuit should be around 12-16 ohms.
