Fuel Injector – Mopar (5281239aa)

Fuel 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 Fuel 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.

Ordering reference for the Fuel Injector is part number 5281239aa, categorised under Fuel Injectors. Match that number against the component you are removing before you order.

Genuine MOPAR supplied for this Fuel Injector, with the engineering number unchanged from the factory reference stamped on the original.
