Walker 211-1093 Engine Coolant Temperature Sensor

Walker 211-1093 Engine Coolant Temperature Sensor

Walker 211-1093 is an engine coolant temperature sensor built to report cooling system temperature data to the ECM in real time. It supports accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control for vehicles that rely on precise temperature input.

Compatible with 2009-2011 Chevrolet Aveo, 2009-2011 Chevrolet Aveo5, and 2009 Pontiac G3, this Sensor Only line part is a direct-fit replacement for common coolant temperature sensor service needs. The oblong female connector and 2-pin layout are designed for factory-style electrical connection.

Key Features

• Engine coolant temperature sensor for ECM temperature reporting
• Direct-fit replacement for OE-style service on Chevrolet Aveo, Chevrolet Aveo5, and Pontiac G3 applications
• 2-terminal pin design with oblong connector shape
• Female connector with male terminals for factory-style mating
• Built with heat-resistant materials for exposure to coolant, vibration, and temperature swings
• Engineered to match OE resistance values, thermal response, and signal output

Product Details

The Walker Sensor Only product line focuses on replacement sensors that integrate with factory systems without unnecessary extras. Walker 211-1093 follows that approach by providing the temperature signal the ECM uses to manage drivability and emissions-related functions. For drivers and technicians servicing a Chevrolet Aveo or Pontiac G3, this coolant temperature sensor helps restore accurate engine temperature feedback when the original sensor is no longer reading correctly.

This part cross-references Standard Ignition TX181 and Four Seasons 55599 for the same application.

Common Problems This Part Can Address

• Check engine light related to coolant temperature sensor performance
• Incorrect coolant temperature readings sent to the ECM
• Hard cold starts or poor cold-start fuel enrichment
• Unstable idle or drivability issues tied to temperature input
• Cooling fan operation problems caused by inaccurate temperature data

Installation Notes and Tips

Verify the connector style, terminal count, and sensor location before installation. This part is listed for 2010-2011 Chevrolet Aveo on the thermostat housing, and for 2009-2011 Chevrolet Aveo5 and 2009 Chevrolet G3 as sensor-only applications. Confirm the vehicle’s original sensor configuration matches the oblong 2-pin design before replacement.

Quality Assurance

Walker Products designs this coolant temperature sensor to align with OE specifications for resistance, thermal response, and signal output, supporting reliable communication with factory engine management systems.
