Injector – GM (19187312)

Injector 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 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 in this listing carries part number 19187312 and sits in the Fuel Injectors category. The number stamped on the original part is the only reliable cross-reference.

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 Where the manufacturer has superseded a number, the current reference is the one that ships.
