Pressure Transducer for 2000-2018 Nissan Altima & More - Four Seasons 20994

Help your air conditioning system keep track of refrigerant pressure with the Four Seasons 20994 HVAC Pressure Transducer / Switch, a system-mounted sensor that reports A/C pressure to the vehicle's controls. It fits many vehicles, among them the 2000-2018 Nissan Altima, 2008-2020 Nissan Rogue and 2000-2019 Nissan Sentra, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.

The transducer monitors refrigerant pressure in the A/C system and turns it into an electrical signal that the vehicle uses to manage air conditioning operation. The part is listed under both names, pressure transducer and switch.

• Zinc coated: A zinc coating helps the transducer resist corrosion.
• Vehicle specific: Built for specific vehicle applications.
• Sealing parts in the box: Contains the gaskets, O-rings or seals needed to replace the unit properly.
• Color coded: Marked by color for easy identification.

Four Seasons engineers and tests its products and backs them with more than 50 years of mobile A/C experience. Signs this part may need replacing include an A/C compressor that won't engage or cycles erratically, warm air from the vents, or a stored pressure-sensor trouble code. These symptoms can have other causes, so diagnose the system first. If a failed pressure transducer is the cause, this part replaces it.
