DTC P0EE3-14: A/C High Pressure Magnetic Valve Circuit Short to Ground or Open [08/2023 - ]: Description

WARNING: This page is about a different car, the 2025 Lexus RX 450h+ and 2024 Lexus RX 450h+. However, it is still accessible from the selected car via links, so may be relevant.

The high pressure magnetic valve (No. 3 magnet valve assembly) is installed to the air conditioner tube and accessory assembly and is open when the ignition switch is turned off. When the ignition switch is turned to ON, the high pressure magnetic valve (No. 3 magnet valve assembly) opens and closes according to heat pump air conditioning control. When heat pump air conditioning control is performing cooling/serial dehumidification heating/cooling battery cooling/single battery cooling/heating/defrosting, the high pressure magnetic valve (No. 3 magnet valve assembly) is closed according to signals from the heat pump ECU assembly. When heat pump air conditioning control is performing parallel dehumidification heating, the high pressure magnetic valve (No. 3 magnet valve assembly) is open.
