Walker Products 211-1042 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1042 Engine Coolant Temperature Sensor (ECT Sensor) is a direct-fit replacement designed to restore accurate coolant temperature monitoring to your vehicle's engine management system. The sensor measures coolant temperature through changing electrical resistance and transmits that data to the onboard computer (ECM/ECU), which uses it to calculate precise fuel delivery, control ignition timing, manage cold start enrichment, and regulate cooling fan operation.

A failed or degraded coolant temperature sensor can trigger a steady check engine light, cause hard starts, engine flooding, and reduced fuel economy. Replacing it with a quality OE-spec unit like the Walker 211-1042 restores proper engine management function.

Key Features:

• Measures coolant temperature via changing resistance and reports to the engine control module (ECM)
• Engineered to match OE specifications for resistance values, thermal response, and signal output
• Built with durable, heat-resistant materials to withstand constant coolant exposure, vibration, and extreme temperature cycles
• Direct-fit design requires no modifications for installation
• 100% tested for peak performance and reliable operation
• Manufactured in an ISO 9001/IATF 16949 certified facility
• Meets or exceeds all Original Equipment Manufacturer (OEM) standards and specifications

Common Failure Symptoms:

• Check engine light (CEL) illuminated
• Hard start or no-start condition
• Engine flooding or rich running condition
• Poor fuel economy
