DPS07002 Denso Pressure Switch OE QUALITY

Denso DPS07002 Pressure Switch – Precision Air‑Conditioning Control

The DPS07002 is a high‑performance pressure switch designed for automotive air‑conditioning systems. It serves as the critical sensor that monitors refrigerant pressure, ensuring optimal compressor operation and protecting the system from over‑pressure or under‑pressure conditions.

Key Functionalities

• Pressure Monitoring: Continuously measures refrigerant pressure within the evaporator and condenser lines.
• Compressor Control: Activates or deactivates the compressor based on preset pressure thresholds, maintaining efficient cooling cycles.
• Safety Protection: Prevents damage to the compressor by shutting it down when pressure exceeds safe limits.
• Low‑Pressure Cut‑off: Stops the compressor if refrigerant pressure drops below a critical level, avoiding potential mechanical stress.

Technical Specifications

Installation Guidelines

1. Locate the Sensor Port: Identify the pressure line where the switch will be mounted. This is typically near the evaporator or condenser.
2. Secure the Threaded Connection: Use a torque wrench to tighten the sensor onto the port, ensuring a leak‑free seal.
3. Wire Connections: Connect the sensor leads to the vehicle’s control module following the manufacturer’s wiring diagram. Verify polarity and continuity before finalizing.
4. Test Functionality: After installation, start the air‑conditioning system and monitor the pressure readings on the diagnostic tool. Confirm that the compressor engages and disengages at the correct pressure points.
