GM Closed Element CLT/Oil Temperature Sensor

This GM-style closed-element sensor is typically used as a fluid temperature sensor, providing accurate readings in a variety of automotive applications. The closed element design ensures long-lasting durability, making it ideal for harsh environments like those found in engine compartments.

Compatible with a wide range of standalone ECUs, including MegaSquirt, MS3Pro, MSPNP, and more, it is perfect for measuring temperatures in both coolant and air intake systems. This sensor uses the common GM calibration, making integration easy with most tuning software.

Features:

• Sensor Usage: typically used for fluids such as coolant, oil, etc
• Closed Element Design: Provides durability and protection in harsh environments
• Universal Fit: Compatible with most aftermarket engine management systems, including MegaSquirt and MS3Pro

Specifications:

• Resistance Range: GM-style thermistor (300 ohms at 210°F, 3400 ohms at 70°F)
• Thread Size: 3/8″ NPT
• Wiring: Standard 2-wire connection (signal and ground)

Wiring:

• Pin A: Sensor Output Signal to ECU
