038 919 081K – Oil Pressure Switch (Brown)

Description

The 038919081K Oil Pressure Switch is a brown, single-pin electrical switch for the engine lubrication system. It monitors oil-pressure status and sends a signal through the vehicle’s warning circuit. Consequently, it helps alert the driver to a possible lubrication concern.

This component uses a single electrical terminal and an OEM-style threaded connection. It replaces earlier switch revisions where applicable. Therefore, always compare the original part number, housing color, connector type, and VIN before ordering.

Why the Oil Pressure Switch Matters

Correct oil pressure is essential for protecting internal engine components. Engine oil lubricates moving parts, reduces friction, and helps control operating heat. Furthermore, a working warning switch provides an important indication when the lubrication system needs inspection.

However, a faulty electrical switch can trigger a warning despite normal oil pressure. For this reason, verify the oil level and inspect the wiring before replacing the part. If a warning remains active, test actual oil pressure using the appropriate diagnostic procedure.

Signs of 038919081K Oil Pressure Switch Failure

Inspect the switch and its connector if you notice any of these symptoms:

• Oil-pressure warning light remains on or flashes unexpectedly.

• Warning light appears even after confirming the correct oil level.

• Oil seepage is visible around the switch body or threaded connection.

• The single-pin terminal is loose, corroded, or damaged.

• The warning changes when the wiring connector is moved.

• The brown switch housing is cracked or contaminated with oil.

Key Features
