LS Swap GM A/C Pressure Sensor T in Fitting

LS Swap GM A/C Pressure Sensor T in Fitting – Brass

Maintain factory-level drivability in your LS-swapped vehicle by integrating the GM A/C pressure sensor directly into your high-side line. This high-quality brass thread-in fitting allows your ECM or PCM to monitor system pressure, enabling the computer to bump the idle and automatically trigger the cooling fans when the A/C is in use. (Idle bump feature is available on most OS options; however, some may not bump the idle on pressure alone.

Technical Specifications

• Material: Premium Brass for superior corrosion resistance and a leak-free seal.

• Installation Type: Thread-in (Designed for easy installation into existing high-side ports).

• System Location: High-Pressure (Discharge) side only.

• Sensor Side Thread Pitch: M10x1.25 (Specifically threaded for the GM A/C Pressure Sensor).

• Line Side Thread Pitch: #6 Threaded Hose.

• Function: Provides the ECM with the necessary data for idle compensation and fan pulse-width modulation (PWM) or relay control.

Installation Note

This fitting is intended for use on the High Side of your A/C system. For proper operation, the GM sensor must be able to read the discharge pressure so the ECM knows when to increase fan speeds to keep head pressures in check.
