Spark Plug – Mopar (68122874aa)

Spark Plug 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 Spark Plug 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.
