2.2.411. SPN 98, FMI 3, Oil level sensor: Electrical signal above normal, possible reason is open circuitΒΆ

Description

The measured oil level signal is above the normal operating range (> 4,98 V).

Possible causes are:

  • The oil level sensor wiring is defective. (Shorted to high source or open circuit.)
  • The oil level sensor power supply is not correct.
  • The oil level sensor is defective.

Reaction in EEM

The FC is stored and the fault lamp is activated. The CAN message indicates an active fault.

Solution

First save the error log and then check the following solutions:

  • Check the oil level sensor wiring, the connectors and the contact surfaces of the connector pins (possible oxidation).
  • Check the 5 V power supply to the sensor.
  • Check the operation with another oil level sensor to see if the oil level sensor is defective.
