Caterpillar 434-3436 is a pressure sensor for the Caterpillar 312D, 320D, 330D and 336D excavators and M325D material handlers. 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.

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.
