A/C Refrigerant Pressure Sensor Overview
Dorman 904-7403 is an A/C refrigerant pressure sensor built to match the fit and function of the original sensor on specified vehicles. It is engineered for durable, reliable performance in the HVAC system and is a direct replacement for common pressure-sensor failures on applications such as Honda Civic and similar vehicle platforms.
Key Features
- Direct-fit A/C refrigerant pressure sensor for specified HVAC systems
- Matches original sensor fit and function for OE-style service
- Black and silver housing with 4-pin male connector
- Screw-on mount with M12-1.25 thread diameter
- Maximum pressure reading: 522
- Dorman 904-7403 for targeted HVAC sensor replacement
Detailed Description
This Dorman A/C refrigerant pressure sensor monitors refrigerant pressure so the HVAC control system can respond correctly to changing operating conditions. The sensor is designed for vehicles that use a screw-on, M12-1.25 threaded pressure switch style with a 4-terminal male connector. If you are replacing a failed A/C refrigerant pressure sensor on a Honda Civic or another listed application, Dorman 904-7403 provides an OE-style service part that follows the original fit and function requirements.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Fix
- Inaccurate refrigerant pressure readings
- A/C compressor cycling problems caused by sensor faults
- HVAC system shutdowns triggered by pressure signal errors
- Intermittent cooling performance from a failing pressure sensor
- Diagnostic trouble codes related to A/C pressure monitoring
Installation Notes and Tips
Verify the connector style, thread size, and mounting style before installation. This sensor uses a screw-on mount with M12-1.25 threads and a 4-pin male connector, so the replacement should match the original HVAC sensor configuration exactly. Confirm the vehicle’s refrigerant pressure sensor location and inspect the connector and sealing surfaces before installing Dorman 904-7403.
Quality Assurance
Dorman engineers this sensor to match original fit and function and to deliver dependable performance in automotive HVAC service. It is built for durability in demanding underhood conditions and is intended as a direct replacement for specified vehicle applications.
