Walker 211-1128 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-1128 is an engine coolant temperature sensor for vehicles that rely on accurate coolant data for ECM control. It provides real-time temperature input for fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation. This Sensor Only line is built for direct replacement service on select Fiat, Jeep, and Dodge applications.

Key Features

• Engine coolant temperature sensor for ECM temperature monitoring
• OE-style resistance values, thermal response, and signal output
• Direct-fit design for factory-style installation
• Heat-resistant construction for exposure to coolant and vibration
• 2-pin terminal design with square female connector
• No wiring harness included

Product Line Details

Walker Products Sensor Only components focus on replacement sensors that match factory electrical behavior and connector style. For applications such as the Fiat 500, Fiat 500L, Fiat 500X, Jeep Renegade, and Dodge Dart, the goal is stable coolant temperature reporting so the ECM can manage engine operation correctly. Part number 211-1128 is engineered for consistent signal delivery in OE-style cooling system service.

Fitment

• Fits 2014-2020 Fiat 500L, Sensor Only
• Fits 2012-2019 Fiat 500, Sensor Only
• Fits 2016-2018 Fiat 500X, Sensor Only
• Fits 2015-2018 Jeep Renegade, Sensor Only
• Fits 2014-2016 Dodge Dart, Sensor Only

What It Helps Address

• Incorrect coolant temperature readings
• Check engine light related to coolant temperature sensor faults
• Hard starting during cold engine operation
• Rich or lean fuel control caused by inaccurate temperature input
• Cooling fan operation issues tied to sensor signal errors

Installation Notes

Verify connector shape, terminal count, and sensor location before installation. Walker 211-1128 uses a square female connector with two pin terminals and no harness, so the existing vehicle connector must match. Confirm the application by year, make, and model before replacing the original sensor.

Quality Assurance

Walker coolant temperature sensors are built to match OE specifications for electrical response and signal output, with durable materials selected for heat and coolant exposure. This helps support reliable integration with factory engine management systems on compatible Fiat, Jeep, and Dodge applications.
