Delphi TS10287 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mazda and Land Rover

Delphi TS10287 is an engine coolant temperature sensor built for accurate coolant temperature reporting to the engine control system. It uses a 2-terminal blade design with a square female connector and threaded nut mounting for a direct-fit replacement on select Mazda and Land Rover applications.

Compatible with Mazda 3, Mazda 5, Mazda 6, Mazda MX-5 Miata, Mazda CX-7, and Land Rover LR3 applications, this Delphi coolant temperature sensor supports reliable temperature input for drivability and engine management. Delphi’s OE heritage and supplier experience are reflected in the part’s construction and fitment-focused design.

Key Features

• Engine coolant temperature sensor for OE-style replacement
• Delphi part number TS10287
• Blade terminal type with 2 terminals
• Single square female connector
• Threaded nut mounting type
• Wiring harness not included
• Package contents: engine coolant temperature sensor and instruction sheet

Detailed Description

Delphi TS10287 is engineered for vehicles that rely on precise coolant temperature data to manage fuel delivery, ignition timing, and cooling-system operation. The sensor’s female square connector, male blade terminals, and threaded nut mounting help support a secure electrical and mechanical connection in the original location. This part cross-references 453 7712 and LR0 19736 for the same application.

For Mazda 3, Mazda 6, Mazda 5, Mazda MX-5 Miata, Mazda CX-7, and Land Rover LR3 fitments, TS10287 provides a direct replacement option when the original engine coolant temperature sensor is worn, inaccurate, or electrically unstable. The Delphi TS10287 part number is also useful when searching for a replacement by OE-style reference.

What This Sensor Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running related to temperature input errors
• Cooling fan operation that does not match engine temperature
• Fuel mixture and idle issues tied to faulty coolant data
• Check engine light conditions related to coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs, and confirm the cooling system is at a safe temperature before removing the old sensor. Use the included instruction sheet during installation and clear diagnostic trouble codes after replacement if required.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. That OE background is built into the design and manufacturing approach behind TS10287, helping support consistent fit and dependable sensor performance.
