Detailed Description
Walker Products 211-2138 is part of the Sensor Only line, focused on replacement sensors that match original equipment specifications without unnecessary extras. This engine coolant temperature sensor helps the ECM manage fuel injection, ignition timing, cold start enrichment, and cooling fan operation by sending accurate temperature data from the cooling system. For drivers and technicians servicing a Genesis G80, Genesis GV80, or Kia Carnival, the correct coolant temperature signal is important for consistent drivability and emissions control.
This part cross-references 392203N030 for the same application.
What It Helps Address
- Incorrect coolant temperature readings
- Check engine light related to temperature sensor faults
- Hard cold starts or poor cold-start fuel delivery
- Cooling fan operation concerns tied to sensor input
- Fuel economy or idle quality issues caused by inaccurate ECM temperature data
Installation Notes and Tips
Verify connector shape, terminal count, and thread style before installation. This sensor uses a 2-pin female oblong connector and does not include mounting hardware, a wiring harness, or thread sealer. Confirm the vehicle application by year, make, and model before replacing the original unit on Genesis G80, Genesis GV70, Genesis GV80, Genesis G90, or Kia Carnival models.
