Febi Bilstein 09489 - oil pressure sensor for Mercedes

Febi Bilstein 09489 - oil pressure sensor

The Febi Bilstein 09489 oil pressure sensor monitors the oil pressure in the engine lubrication system and sends a signal to the dashboard gauge or the engine control unit. A detected pressure drop below a safe level triggers a warning light, informing the driver of a potential threat to the engine.

Application

The part fits Mercedes-Benz T2 commercial vehicles (models 668 and 669) and EvoBus buses. It corresponds to the original Mercedes-Benz/EvoBus part number 004 542 89 17. The sensor has an M14 x 1.5 external thread, 12 mm long, and a switching measuring range of 0 to 5 bar, with a 19 mm wrench size.

When to replace the oil pressure sensor

A faulty oil pressure sensor can give false readings - the oil pressure light comes on even though the oil level and pressure are correct, or conversely does not react to an actual pressure drop. Because the sensor is one of the key components protecting the engine from running without proper lubrication, it is worth replacing it with a working, original-quality part as soon as incorrect readings are noticed.
