- Oil condition sensor (OEZS)
General information
Fig. 65: Oil condition sensor in the lower section of an oil sump which has been
removed
An oil condition sensor was built in the engine's oil sump to
record the exact engine oil level, oil temperature and the
condition of the engine oil.
Recording the engine oil level protects the engine from having
an oil level which is too low and thereby from the resultant
engine damage.
Recording the condition of the oil, means that it is possible to
determine exactly when an oil change is required.
