Frequently Asked Questions

Q: What vehicles is this LPG/CNG PS04 pressure sensor compatible with?

A: This PS04 differential pressure sensor is designed for use in vehicles equipped with LPG (liquefied petroleum gas) or CNG (compressed natural gas) oil-to-gas conversion systems that use PS04-type sensor configurations. Always verify the sensor type used in your specific conversion kit before purchasing.

Q: Is this a direct replacement for the OEM PS04 sensor?

A: Yes, this is a new, high-quality aftermarket replacement designed to fit standard PS04 system mounting points. It is intended as a like-for-like swap to restore proper pressure sensing function in your LPG or CNG gas auto system.

Q: What does a differential pressure sensor do in an LPG/CNG system?

A: The differential pressure sensor monitors the pressure difference within the gas conversion system — typically measuring intake air and gas supply pressures. This data helps the system's control unit regulate fuel delivery for efficient engine operation when running on LPG or CNG.

Q: How do I install the PS04 pressure sensor?

A: Installation involves disconnecting the old or faulty sensor from its mounting point and electrical connector, then fitting the new sensor in its place. It is recommended that installation be performed by a qualified automotive technician familiar with LPG/CNG conversion systems.
