Walker 211-91070 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Jaguar and Mazda

Walker 211-91070 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. With a direct-fit design and OE-matched electrical characteristics, it supports accurate fuel delivery, ignition timing, cold start enrichment, and cooling fan control.

Compatible With select Jaguar E-Pace, F-Pace, F-Type, XF, I-Pace, XE, XJ, XJR575, XJR, XFR, XFR-S, XK, XKR, and XKR-S applications, plus Mazda 6 and Mazda MPV models. Walker Products Full Service Kit coverage is aimed at technicians and DIY repairs that need a precise replacement sensor for factory-style operation.

Key Features

• Part number 211-91070 engine coolant temperature sensor
• Blade terminal type with 2 terminals
• Rectangle female connector for direct electrical connection
• No wiring harness included
• Engineered to match OE resistance values, thermal response, and signal output
• Heat-resistant construction for exposure to coolant, vibration, and temperature swings
• Direct-fit replacement for factory-style installation

How It Works

The coolant temperature sensor sends temperature data from the cooling system to the ECM so the engine can adjust fueling, ignition timing, cold start enrichment, and radiator fan operation. On Jaguar XF, Jaguar F-Pace, and Mazda 6 applications, accurate sensor output helps the control module respond correctly to changing engine temperatures and maintain stable drivability.

Walker Products 211-91070 is built for consistent signal delivery and OE-style integration with factory systems. The Full Service Kit line focuses on service parts that match original specifications for fit and electrical performance.

Common Problems This Sensor Can Address

• Check engine light related to coolant temperature sensor circuit faults
• Hard starting during cold engine operation
• Incorrect fuel mixture caused by inaccurate temperature readings
• Cooling fan operation that does not match engine temperature
• Poor fuel economy or rough running from incorrect ECM temperature input

Installation Notes

Verify connector shape, terminal count, and sensor location before installation. This unit uses a rectangle female connector with blade terminals and does not include a wiring harness. Confirm the vehicle application and coolant sensor mounting point, especially on listings that note radiator coolant hose location.
