SPM-HEP-4581 is the oil pressure sensor: a stainless steel hex body with a threaded port and O-ring, and a black four pin round plug with a twist lock. It is used on Volvo D13 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.
It replaces Volvo 22899626, Volvo 21634021 and Volvo 20634019.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

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.

Yes, it was made for the Volvo D13, and 2 more listed under compatible equipment. Check the old sensor is marked 22899626 or one of the cross references, because makers change parts between serial ranges.
On the Volvo D13, 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.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
Read the fault codes, then check the plug and wiring for corrosion or a broken wire. A wiring fault reads the same as a failed sensor.
No. It is an aftermarket sensor made to replace the Volvo 22899626. It is not made by the original manufacturer; the number only shows what it replaces.
