Spark Plug – Mopar (68644215AA)

Spark Plug is an electrically controlled component in the engine or transmission management system. Because the module cross-checks it against other inputs, a fault here often surfaces as a code for a different circuit.

Replace the Spark Plug when a value freezes or drops out intermittently, which usually means an internal fault rather than wiring. Wiggle-testing the harness while watching live data separates the two.

This Spark Plug is listed under part number 68644215AA, filed under Spark Plugs & Ignition. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.
