Volvo 20634019 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.
The same part is also sold as Volvo 21634021 and Volvo 22899626.
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 fit my Volvo D13?
Yes, it was made for the Volvo D13, and 2 more listed under compatible equipment. Check the old sensor is marked 20634019 or one of the cross references, because makers change parts between serial ranges.
How often should I replace the sensor on my Volvo D13?
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.
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.
Should I grease the connector?
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
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 Volvo 20634019?
No. It is an aftermarket sensor made to replace the Volvo 20634019. It is not made by the original manufacturer; the number only shows what it replaces.
