DTC P2611-14: A/C Low 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 low pressure magnetic valve (No. 1 magnet valve assembly) is installed to the No. 2 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 low pressure magnetic valve (No. 1 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/, the low pressure magnetic valve (No. 1 magnet valve assembly) is closed according to signals from the heat pump ECU assembly. When heat pump air conditioning control is performing heating/parallel dehumidification heating/defrosting, the low pressure magnetic valve (No. 1 magnet valve assembly) is open.
