This article offers detailed wiring diagrams for air and fluid temperature sensors, helping you correctly integrate these sensors into your setup. Whether you’re monitoring intake air temperature or fluid temperatures like coolant or oil, these diagrams provide clear guidance to ensure accurate readings and reliable performance. Use these resources to simplify your installation process and achieve precise temperature monitoring.
Note: The wiring is not polarized, meaning that the Ground and Signal wires can be connected to either pin without affecting functionality

Checking for Pre-installed Bias Resistor (ex: CLT or IAT)
- ECU: Powered OFF
- Multimeter: Set it to Ohms
- Probes:
- Black Probe to Yellow Signal Wire
- Red Probe to 5V Vref
- Reading: 2.49kΩ means necessary resistor is present
