Denso 475-2041 A/C Expansion Valve - Rear

Denso New Expansion Valve 475-2041

Denso 475-2041 is a new expansion valve for rear A/C systems that rely on precise refrigerant control at the evaporator. This angle valve helps separate the low and high sides of the air conditioning circuit so the system can regulate refrigerant flow correctly in supported Honda Odyssey and Toyota rear A/C applications.

Key Features

• Angle valve design for rear air conditioning service
• Controls liquid refrigerant flow through the evaporator
• OE-specified O-rings included for the listed applications
• Built for vehicles that require accurate A/C calibration
• Direct replacement part number 475-2041

Product Details

Denso’s New Expansion Valve line focuses on correct refrigerant metering for vehicle-specific HVAC systems. In rear A/C applications, the expansion valve must match the system calibration closely; if flow is off, the evaporator can lose heat-exchange efficiency or freeze, which can lead to additional A/C damage. This part number 475-2041 is used in rear HVAC service for 2005-2010 Honda Odyssey, 2001-2007 Toyota Sequoia, and 2004-2007 Toyota Sienna rear A/C configurations. This part cross-references Honda 80221-SHJ-A51 and Toyota 88515-0C030 for the same application.

What It Helps Address

• Rear A/C blowing warm air
• Evaporator icing or freeze-up
• Incorrect refrigerant metering at the evaporator
• Poor cooling performance in rear HVAC zones
• System damage caused by improper expansion valve calibration

Installation Notes and Tips

• Verify the vehicle’s rear A/C configuration before ordering.
• Match the valve type and application to the original system layout.
• Inspect the evaporator circuit and related seals during service.
• Use proper A/C service procedures when opening the refrigerant system.

Quality Assurance

Denso draws on decades of OE component and system engineering for automakers, and this expansion valve is built to meet the application-specific requirements of the listed vehicles. The New Expansion Valve product line is intended to provide the correct refrigerant control characteristics for the vehicle platform.
