INJECTOR – Mopar (R5135790AF)

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.

Ordering reference for the INJECTOR is part number R5135790AF, categorised under Fuel Injectors. Match that number against the component you are removing before you order.

The stock here is genuine MOPAR, and this INJECTOR keeps the original engineering number, which matters once a number has been superseded more than once.
