What It Helps Resolve

• Air conditioning compressor cycling caused by a faulty pressure transducer
• Incorrect refrigerant pressure signal to the HVAC control system
• Intermittent A/C operation in Volvo C30, C70, S40, and V50 models
• Loss of system protection logic tied to refrigerant pressure monitoring
• Electrical connection issues at the pressure switch interface

Installation Notes

Verify the connector shape, terminal count, and M10x1.250 thread before installation. This is a system-mounted pressure transducer for R134a applications, so the replacement should match the original sensor style and fitting specification. Confirm vehicle-specific fitment for the exact Volvo model and year before service.
