Delphi TS10573 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Nissan and INFINITI

The Delphi TS10573 engine coolant temperature sensor provides OE-style temperature signal input for the engine management system. It is built with a threaded mounting design, a male oval connector, and a 2-terminal pin layout for direct replacement service on select Nissan and INFINITI applications.

Compatible With 2007-2022 Nissan Altima, 2009 and 2016-2021 Nissan Maxima, 2011-2022 Nissan Sentra, and other listed Nissan and INFINITI models. The Delphi TS10573 is a practical choice when replacing a faulty coolant temperature sensor on vehicles such as the Nissan Rogue, Murano, Pathfinder, and INFINITI QX60.

• Engine coolant temperature sensor for OE-style temperature reporting
• Threaded mounting type for secure installation
• Oval male connector with 1 connector and 2 terminals
• 19 mm head tool size for service access
• No wiring harness included
• No thread sealer included

Detailed Product Overview

Delphi TS10573 is engineered from OE heritage and validated with technical requirements shaped by more than 100 years of original-equipment experience. Material selection, thickness, and construction follow OE specifications, while manufacturing controls are used to maintain consistent part quality. This sensor is designed for vehicles that rely on accurate coolant temperature input for fuel control, idle strategy, and engine protection logic. This part cross-references Genuine 22630-JA10A for the same application.

Common Problems This Sensor Can Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough cold operation caused by inaccurate temperature input
• Rich or lean fuel control issues related to sensor signal drift
• Cooling fan operation concerns tied to faulty temperature data
• Check engine light conditions associated with coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and thread size before installation. The Delphi TS10573 uses a threaded mount and a 19 mm head tool size, so access to the sensor location should be checked before service begins. Because no thread sealer is included, confirm the sealing method required by the vehicle service procedure. Always inspect the connector and harness condition before installing the new sensor.

Quality Assurance

Delphi builds this sensor using OE-based design specifications and validation testing to help maintain consistent fit and signal performance across listed applications. The part number TS10573 is also referenced in aftermarket cross-reference listings for select Nissan and INFINITI coolant temperature sensor applications.
