Walker 211-1077 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Subaru

Walker Products 211-1077 is a sensor-only engine coolant temperature sensor built to deliver accurate coolant temperature data to the ECM. It supports fuel injection, ignition timing, cold start enrichment, and cooling fan operation for Subaru applications including Forester, Impreza, Legacy, Outback, BRZ, and XV Crosstrek.

Sensor Features

• Engine coolant temperature sensor for real-time ECM temperature input
• OE-style resistance values, thermal response, and signal output
• Direct-fit design for factory-style replacement
• Heat-resistant construction for exposure to coolant, vibration, and temperature swings
• 2-terminal blade pin design with oblong female connector and male terminals
• Walker Products Sensor Only line focused on replacement sensors without added assemblies

Detailed Product Information

Walker Products 211-1077 is engineered for accurate coolant temperature reporting so the ECM can adjust engine operation based on current cooling system conditions. This matters on Subaru Forester, Subaru Impreza, Subaru Legacy, Subaru Outback, Subaru BRZ, and Subaru XV Crosstrek models where precise temperature input affects drivability, emissions control, and fan strategy. The Sensor Only product line keeps the focus on the replacement sensor itself, making it a straightforward choice when servicing a failed coolant temperature sensor or diagnosing a check engine light.

This part cross-references 211-1077 for the same application.

What It Helps Resolve

• Check engine light related to coolant temperature sensor signal faults
• Hard starting during cold engine operation
• Incorrect fuel mixture from inaccurate temperature input
• Unstable idle or poor warm-up behavior
• Cooling fan operation issues tied to temperature reporting

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This sensor uses a blade pin terminal type, oblong connector shape, 2 terminals, a female connector, and male terminals. Confirm the vehicle application against the listed Subaru fitment before replacing the original part.
