MID 036 - CID 0543 - FMI 02 Filtered Oil Pressure Sensor misinstalled
Conditions Which Generate This Code:
The Electronic Control Module (ECM) reads a negative differential pressure between the unfiltered engine oil pressure sensor and the filtered engine oil pressure sensor. The sensors may be installed incorrectly. The diagnostic codes for the analog sensor power supply 262-03 and 262-04 are not "ACTIVE".
System Response:
The CID-FMI is logged in memory. The CID-FMI may be viewed on a display module or the Caterpillar Electronic Technician (ET). The ECM flags the unfiltered engine oil pressure as invalid data. The engine monitoring system is disabled for filtered engine oil pressure.
Test Step 1.
Correctly install the sensor.
Results:
- REPAIRED, OK - Stop.
