Leakage Between Oil Level Sensor and Oil Pan

If you receive customer reports in the above model vehicles of oil leakage between the oil level sensor and the oil pan, the cause maybe due to the

sealing ring being damaged by the burr at the oil pan installation hole. To resolve, remove and replace only the sealing ring as per the parts

information listed below.

Lightly oil the sealing ring prior to installation.

NOTE:

In case of oil leakage only, do not replace the oil level sensor assembly. Replace the O-ring only. All replaced oil level sensors solely due to oil

leakage will be debited back to the dealer.

Inspect the surface of the oil pan oil level sensor installation hole. If extreme roughness or sharp edges are found, de-bur the rough surface of the oil

pan hole with an emery cloth.
