Description

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
  • Pin B: Sensor Ground

IMPORTANT NOTE: The pins for this connector are pull-to-seat! This means you cannot push the pins into the connector from the back.

 

Calibration:

If you need to calibrate your MS for this sensor, here’s the calibration data we use for them for a three point curve.

Temp (deg F)    Ohms
   48     7000
   87     1930
  146     560

Included in the Box:

  • GM Closed Element CLT / IAT Sensor
  • Depends on option chosen:
    • Connector & Pins
    • 6″ Pigtail

What size hole do I need to drill to install this sensor?

  • The hole should be tapped for 3/8″ NPT.  Your tap will come with instructions for the preferred drill size, which is likely to be 9/16″.

What is its resistance vs temperature curve?

  • If you are connecting this to a device that supports 3 point calibration (all MegaSquirt units do), use these numbers if your device does not have a standard GM temperature sensor calibration curve.
    • 7000 ohms at 48 degrees F
    • 1930 ohms at 87 degrees F
    • 560 ohms at 146 degrees F

I am using it with a device that requires a voltage vs temperature curve. What data do I enter?

  • This sensor outputs resistance, not voltage. You will need additional, external circuitry to convert its output into a voltage, and the voltage will depend on the design of the external circuit.

Can I buy the connector separately?

  • We currently buy the sensor and connector as a single item and do not stock the connector on its own.
