Walker 211-2164 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Ford Aspire

Walker 211-2164 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. For a 1997 Ford Aspire, this sensor supports accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

Walker Products Sensor Only line focuses on direct replacement sensors engineered for OE-style electrical response and dependable signal output. The 211-2164 is made for factory-style integration in the cooling system, with a heat-resistant construction that handles coolant exposure, vibration, and repeated temperature changes.

• Fits 1997 Ford Aspire, Sensor Only
• Blade terminal type with oblong connector shape
• 2-terminal, female connector design
• Direct-fit replacement for factory-style installation
• Built for stable resistance values and thermal response
• Walker 211-2164 for coolant temperature signal accuracy

How This Sensor Works

The engine coolant temperature sensor measures coolant temperature and sends that data to the ECM so the system can adjust engine operation in real time. On a Ford Aspire, that input affects starting behavior, fuel mixture, ignition timing, and radiator fan operation. Walker 211-2164 is engineered to match OE specifications for resistance and signal output, helping the vehicle’s control system read temperature correctly.

This part cross-references Ford F7BZ12A648AA for the same application.

Common Problems It Can Help Solve

• Check engine light related to coolant temperature sensor readings
• Hard cold starts or extended warm-up behavior
• Incorrect fuel mixture from inaccurate temperature input
• Cooling fan operation that does not match engine temperature
• Poor drivability caused by unstable ECM temperature data

Installation Notes

Verify the connector style before installation: this sensor uses a female connector with an oblong shape, 2 blade terminals, and no wiring harness included. Confirm the replacement matches the original sensor location and electrical connection on the 1997 Ford Aspire before installation.

Quality Assurance

Walker Products builds this Sensor Only coolant temperature sensor to OE-style resistance and thermal response standards for reliable integration with factory systems. The heat-resistant construction is selected for continuous exposure to coolant and engine-bay temperature swings.
