Compatibility Notice

Model, production date, serial number, dimensions, electrical or mounting configuration, installed options, and previous repairs can affect fitment. Compare the removed part and equipment information before purchase.
Frequently Asked Questions
Q: Can a blocked line make the sensor look bad? A: Yes. Restricted, leaking, or reversed sensing passages can produce incorrect differential-pressure readings.
Q: Should I replace the sensor based only on a fault code? A: No. A code identifies the circuit or reading problem; wiring, ports, and actual pressure still need to be tested.
Q: How do I confirm fitment before ordering? A: Match the original reference number, equipment model and serial number, dimensions, connector or mounting details, and the product photos. Do not rely on appearance alone.
Q: Is this made by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and model numbers are used only to identify compatible equipment.
