Standard Ignition TS-181 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Standard Ignition TS-181 is an engine coolant temperature sensor built for accurate coolant temperature signal input to the engine management system. It uses a bolt-on attachment with a round, plug-in male connector and a single male bullet terminal for a direct-style electrical connection.

For drivers searching for an engine coolant temperature sensor for Hyundai, Kia, or other import applications, TS-181 is a practical replacement part number to verify against the original sensor before ordering.

Key Features

• Engine coolant temperature sensor for temperature signal monitoring
• Bolt-on attachment method for secure mounting
• Round, plug-in connector with male terminal design
• Single-terminal configuration with bullet-style terminal
• Standard Ignition TS-181 replacement part number
• Cross-references Standard Ignition TS-181 and related numbers such as 25242KA100

Detailed Description

Standard Ignition TS-181 is an engine coolant temperature sensor used to report coolant temperature to the vehicle control system. That signal can affect fuel delivery, idle quality, cooling fan operation, and temperature-related engine strategy. The connector and terminal layout are important for proper electrical matching, so confirm the round plug-in connector, male terminal, and bolt-on mounting style against the original part.

This part number is commonly searched by buyers looking for a coolant temperature sensor for Hyundai and Kia applications, including Hyundai Elantra and Kia Spectra fitment references where applicable. When replacing a faulty sensor, matching the original connector shape and attachment method helps ensure the new sensor installs correctly and communicates the expected temperature reading. Standard Ignition TS-181 is also referenced by part number TS-181 in catalog searches.

What It Helps Address

• Incorrect coolant temperature readings
• Hard starting when the engine is cold
• Rough idle caused by inaccurate temperature input
• Cooling fan behavior tied to a faulty sensor signal
• Check engine light concerns related to coolant temperature data

Installation Notes

Verify connector style, terminal type, and mounting method before installation. Inspect the harness connector for corrosion or looseness, and compare the old sensor’s physical design to TS-181 before removal. Use the vehicle service procedure for coolant system handling and sensor torque specifications.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TS-181 is cataloged as an engine coolant temperature sensor replacement part and should be matched to the original application by part number and connector design.
