Common Problems This Part Can Address

• Inaccurate A/C pressure signal to the HVAC control system
• Compressor cycling caused by a faulty pressure transducer
• Loss of refrigerant pressure feedback in system-mounted applications
• HVAC performance issues on Lexus GX460, RX350, IS350, and similar Toyota models
• Diagnostic trouble codes related to pressure sensor input

Installation Notes and Tips

Verify the connector shape, 3-pin terminal count, and M11 x 1.00 thread before installation. Confirm the vehicle’s HVAC system uses a system-mounted pressure transducer and match the application by year, make, and model. After replacement, inspect the refrigerant system for leaks and clear any stored HVAC or engine codes as required by the vehicle service procedure.

Quality Assurance

This Four Seasons pressure transducer is manufactured to meet or exceed OEM requirements for the listed applications. Confirm fitment against the vehicle’s HVAC configuration before ordering, especially on Lexus GX460 models with rear A/C or dual-zone climate control notes.
