FAQs
What does an air conditioning pressure switch do?
An AC pressure switch monitors the high and low pressure within the vehicle's air conditioning system. It protects components by signaling the compressor to turn off if pressures are too high or too low, and it enables the system to operate efficiently.
How do I know if my pressure switch needs replacing?
Symptoms can include poor cooling performance, the AC compressor cycling on and off rapidly, or the compressor not engaging at all. A diagnostic scan may also reveal pressure-related error codes.
Is this switch compatible with all vehicles?
No, this is a specific replacement part for DENSO DPS99906. You must verify that your vehicle requires this exact part number and specifications (thread size, plug type) before purchasing.
What is the thread size of this switch?
The thread size is 7/16"-20 UNF-2B.
What type of electrical connector does it have?
It features a female plug type.
What is the weight of the switch?
The weight of the switch is 81g.

Troubleshooting
AC system not cooling effectively.
Verify the pressure switch is correctly installed and connected. Low refrigerant levels or other system issues might be the cause, requiring a full system diagnosis.
AC compressor not engaging.
Check electrical connections to the pressure switch. The switch may be faulty if low pressure is detected, or it could indicate a problem with the compressor clutch or wiring.
AC system pressure warning lights/indicators are active.
This could indicate an over-pressure or under-pressure situation. Ensure the pressure switch is functioning correctly and that refrigerant levels are appropriate.
Leaking around the pressure switch connection.
Carefully tighten the switch, ensuring not to overtighten. If the leak persists, the switch may need to be replaced, potentially with a new sealing washer if applicable to the installation.
