Walker 211-2018 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2018 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. Accurate temperature input supports fuel delivery, ignition timing, cold start enrichment, and cooling fan operation on applications such as Ram 1500, Chrysler 300, and Jeep Cherokee.

Walker Sensor Only products focus on OE-style signal accuracy and direct-fit replacement for factory systems. Part number 211-2018 is engineered for reliable resistance values, thermal response, and output consistency in demanding underhood conditions.

Key Features

• Blade terminal type with a 2-terminal female rectangle connector
• Direct-fit engine coolant temperature sensor for factory-style replacement
• Matches OE specifications for resistance values, thermal response, and signal output
• Heat-resistant construction for exposure to coolant, vibration, and temperature swings
• No wiring harness included
• Cross-reference: Mopar 68164627AA

Detailed Product Description

This Walker engine coolant temperature sensor monitors coolant temperature and sends that data to the ECM so the engine can adjust operating strategy in real time. On vehicles such as the 2013-2018 Ram 1500, 2017-2023 Chrysler 300, and 2016-2022 Jeep Cherokee, accurate sensor output is important for drivability, emissions control, and cooling system management. The 211-2018 is built as a direct replacement for the original sensor and uses a blade terminal, female rectangle connector design for factory-style integration.

Walker Products Sensor Only components are focused on the sensor itself, making this part a practical choice when replacing a failed coolant temperature sensor or diagnosing a check engine light tied to temperature signal faults. Part number 211-2018 is also listed with interchange references including Standard Ignition TX259 and Motorad 1TS1167 for the same application.

What This Sensor Helps Address

• Check engine light related to coolant temperature signal errors
• Hard starting during cold engine operation
• Incorrect fuel mixture caused by inaccurate temperature input
• Unstable idle or drivability concerns after warm-up
• Cooling fan operation issues tied to temperature reporting

Installation Notes

Verify connector shape, terminal count, and vehicle application before installation. This sensor uses a 2-terminal female rectangle connector with blade terminals and does not include a wiring harness. Confirm the original sensor location and inspect the connector and cooling system condition before installing the replacement.

Compatible vehicle coverage includes 2013-2018 Ram 1500, 2017-2023 Chrysler 300, 2016-2022 Jeep Cherokee, 2017-2020 Dodge Grand Caravan, and 2015-2017 Chrysler 200. Additional coverage includes 2014-2016 Chrysler Town & Country, 2014-2016 Dodge Grand Caravan, 2015 Jeep Cherokee, 2014-2015 Ram C/V, and 2019-2024 Ram 1500 Classic.
