Q: What Volvo truck models use this pressure sensor?
A: The COGENG universal pressure sensor is a direct OEM replacement for Volvo part numbers 20476992, 64MT475M, 20824479, 20449988, and 22443498, designed for various Volvo truck models and engines where these sensor part numbers are specified. Common applications include engine oil pressure, fuel pressure, air system pressure, or other critical pressure monitoring circuits. The multiple part numbers represent different supersessions and cross-references. Always verify the correct part number for your specific application against your vehicle's parts manual before ordering.
Q: What is the relationship between these five part numbers?
A: These five part numbers (20476992, 64MT475M, 20824479, 20449988, and 22443498) represent the same or functionally equivalent pressure sensors across different Volvo and Mack truck applications and production periods. Some numbers may be supersessions or updates of earlier versions, while others represent cross-references for the same sensor used in different vehicle systems. The COGENG sensor is designed to be a direct replacement for all five part number references.
