Walker 211-91050 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Ram and Titan XD

Walker 211-91050 is an engine coolant temperature sender built to deliver accurate temperature data to the ECM. It supports proper fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation for vehicles that rely on precise coolant temperature input.

Compatible With 1998-2021 Ram 2500, Ram 3500, and 2016-2019 Nissan TITAN XD applications, this Full Service Kit line item is engineered for direct-fit replacement service. The Walker Full Service Kit product line focuses on OE-style fit and signal accuracy for technicians replacing a failed coolant temperature sender or diagnosing a check engine light.

• Blade pin terminal type with 2 terminals
• Oblong connector shape with female connector gender and male terminal gender
• Engine coolant temperature sender for ECM temperature input
• OE-matched resistance values, thermal response, and signal output
• Heat-resistant construction for coolant exposure, vibration, and temperature swings
• Direct-fit design for factory-style installation

Detailed Product Overview

Walker Products part number 211-91050 is designed to provide stable coolant temperature readings so the ECM can manage engine operation accurately. By matching OE specifications for resistance and response, this sender helps maintain consistent communication with factory engine management systems. It is a practical replacement for Ram 2500 and Ram 3500 trucks across multiple model years, as well as Nissan TITAN XD applications listed in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Incorrect coolant temperature readings sent to the ECM
• Check engine light related to temperature sensor performance
• Hard cold starts caused by inaccurate temperature input
• Improper fuel injection or ignition timing control
• Cooling fan operation problems tied to sender signal errors

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. The oblong female connector and blade pin terminals should match the vehicle harness and factory sensor interface. Confirm the cooling system is at a safe temperature before removing the old sender, and inspect the connector and sealing surface during service.

Quality Assurance

Walker Products engineers this coolant temperature sender to OE specifications for resistance, thermal response, and output signal, with durable materials selected for long-term exposure to coolant and engine heat.
