97721D9000 Hyundai / KIA SENSOR-PRESSURE, Price: 55.30$, Weight: 0.04kg

AC Refrigerant Pressure Sensor for Hyundai/Kia ❄️

Why you need it

This sensor reads the refrigerant pressure in the high-side line and sends live data to the HVAC/engine computer. With accurate pressure info, the system controls the compressor clutch or variable compressor, cycles the condenser fans, protects the loop from over/under pressure, and keeps the cabin cool fast while saving fuel. Without it, the AC can’t manage load or safety—comfort and component life suffer.

How it works ⚙️

A solid-state transducer converts line pressure into a precise voltage. The ECU uses that signal to modulate compressor output, adjust fan speed, and shut the AC if pressure goes out of safe limits. Stable readings mean steady vent temps and longer compressor life.

What happens if it fails ⚠️

• No-cool or weak AC; compressor won’t engage or short-cycles
• Condenser fans run constantly or never start
• Warning lamp and stored pressure sensor DTCs
• Risk of blown seals (overpressure) or compressor damage (low oil flow)

Pro tips

Recover refrigerant before removal, replace the O-ring, torque correctly, then vacuum and recharge by weight. Clear codes and verify live pressure data. Do not overtighten the aluminum port.
