Standard Ignition TX115 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Kia Applications

Standard Ignition TX115 is an engine coolant temperature sensor built for direct replacement service on select Kia vehicles. It uses a brass body with a bolt-on attachment, a square plug-in connector, and a M12-1.50 thread size for a straightforward OE-style fit.

Compatible with 1999-2001 Kia Sephia, 2000-2001 Kia Spectra, and 2001-2004 Kia Rio, this sensor supports accurate coolant temperature reporting to the engine control system. It is also listed for 2005 Kia Rio built to 5/05.

Key Features

• Standard Ignition TX115 engine coolant temperature sensor
• Brass sensor body for durable coolant-system service
• Bolt-on attachment method for secure mounting
• Square, female plug-in connector with 3 male blade terminals
• M12-1.50 thread size for the specified applications
• Direct-fit replacement for select Kia Rio, Sephia, and Spectra models

Detailed Description

The TX115 coolant temperature sensor monitors engine coolant temperature and sends that information to the vehicle’s control system for fuel and drivability calculations. On the listed Kia applications, a worn or inaccurate sensor can affect temperature reporting and engine management. Standard Ignition TX115 is built with a brass sensing body, a square connector interface, and a bolt-on design to match the specified OE-style mounting and electrical connection.

This part cross-references Beck/Arnley 158-0627 and Walker Products 211-1063 for the same application. It is a practical replacement choice for Kia Rio, Kia Sephia, and Kia Spectra service where the original coolant temperature sensor has failed or is reading incorrectly.

Common Problems This Part May Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting when the engine is cold
• Rough idle caused by inaccurate temperature input
• Poor fuel control from a faulty engine coolant temperature sensor
• Check engine light related to coolant temperature sensor performance

Installation Notes and Tips

Verify connector shape, terminal style, and thread size before installation. Inspect the coolant passage and electrical connector for corrosion, damaged terminals, or contamination before fitting the new sensor. Confirm the application by model year, since the 2005 Kia Rio listing applies only to vehicles built to 5/05.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TX115 is cataloged as a direct replacement coolant temperature sensor for the listed Kia applications and is built to match the specified connector and thread requirements.
