Walker 211-2118 Engine Coolant Temperature Sensor
Engine Coolant Temperature Sensor for Infiniti
Walker 211-2118 is a direct-fit engine coolant temperature sensor for select Infiniti applications. It provides the ECM with coolant temperature data used for fuel delivery, ignition timing, cold start enrichment, and cooling fan control.
Key Features
- Blade terminal type with oblong female connector
- 2-terminal sensor-only design
- OE-style resistance values, thermal response, and signal output
- Heat-resistant construction for constant coolant exposure and vibration
- Direct-fit replacement for factory-style installation
Product Details
Walker Products Sensor Only line focuses on replacement sensors built to match factory electrical behavior and connector style. Part number 211-2118 is engineered for accurate coolant temperature reporting so the ECM can manage engine operation with the correct temperature input. This sensor is used on 2016-2019 INFINITI Q50 and on 2017 INFINITI Q60 through 07/2017, making it a targeted replacement for vehicles that need a reliable coolant temperature signal. This part cross-references Honda (e.g., 22630HG00D) for the same application.
What It Helps Address
- Check engine light related to coolant temperature sensor faults
- Hard cold starts or extended warm-up behavior
- Incorrect fuel mixture caused by inaccurate temperature input
- Cooling fan operation problems tied to sensor signal errors
- Poor fuel economy or drivability issues from bad ECM temperature data
Installation Notes
Verify connector shape, terminal count, and sensor location before installation. This sensor uses a blade terminal, oblong female connector, and no wiring harness is included. Confirm the vehicle is a 2016-2019 INFINITI Q50 or a 2017 INFINITI Q60 built through 07/2017 before ordering part number 211-2118.
Quality Assurance
Walker Products designs these sensors to OE specifications for resistance, thermal response, and output signal, with durable materials selected for coolant-system heat and vibration exposure.
