Injector – GM (19146288)

Injector converts a physical condition into a signal the powertrain module acts on. The module compares that signal against an expected range at every start-up, so a failing unit is usually logged before it becomes a driveability complaint.

Replace the Injector when the fault repeats with the harness already ruled out, when resistance drifts as the part heats up, or when a connector has corroded past cleaning. Swapping a sensor to chase a wiring fault is the most common wasted repair on these circuits.

For this Injector the reference is 19146288, in our Fuel Injectors range. Compare it with the number on the part you are replacing rather than with a photograph.
