Transfer Case Fluid Temperature Sensor – GM (19179158)

Transfer Case Fluid Temperature Sensor 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 Fluid Temperature Sensor 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 Fluid Temperature Sensor in this listing carries part number 19179158 and sits in the Sensors & Switches category. The number stamped on the original part is the only reliable cross-reference.

Genuine GM supplied for this Fluid Temperature Sensor, with the engineering number unchanged from the factory reference stamped on the original.
