Fuel Injector O Ring – Mopar (68299403aa)

Fuel Injector O Ring is part of the circuit that reports engine or transmission behaviour back to the control module. It is read continuously, and a value that drifts out of range sets a fault code long before the driver notices anything.

Replace the Injector O Ring when the code returns after clearing, when the live data reading is out of range at operating temperature, or when the housing shows heat damage. Check the ground and the connector pins first.

The Injector O Ring in this listing carries part number 68299403aa and sits in the Fuel Injectors category. The number stamped on the original part is the only reliable cross-reference.

Genuine MOPAR part for the Injector O Ring. Where the manufacturer has superseded a number, the current reference is the one that ships.
