Cummins 4928593 is the threaded brass pressure sensor with a three pin sealed plug. It is used on Cummins ISX and ISM engines. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
The same part is also sold as Cummins 4087987.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Applications & use cases
Wrong or missing reading
A failed sensor gives a dead or false gauge reading or a warning light.
Fault codes
Check the wiring and plug first; if the sensor itself reads out of range, replace it.
Corrosion
Connectors on machines take water and dirt. A corroded sensor is cheaper to replace than to chase.
Fleet spares
Common sensors are worth keeping in stock for each machine type.

Frequently asked questions
Will it replace my Cummins 4928593?
Yes, it is a direct replacement for the Cummins 4928593 with the same fitting.
How often should I replace the Cummins 4928593?
There is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
What are the signs the sensor needs replacing?
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Do the fault codes need clearing?
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
Does the voltage matter?
Yes. Many machines have 12 V and 24 V versions of the same sensor. Check the old part or the machine plate before fitting.
Is this a genuine Cummins 4928593?
No. It is an aftermarket sensor made to replace the Cummins 4928593. It is not made by the original manufacturer; the number only shows what it replaces.
