CAT 102 · FMI 7
Intake mfld pres sensor

What this code means

Component / fault: Intake mfld pres sensor.
Reported detail: not responding.
FMI 7 in the SAE J1939 / Caterpillar CDL convention means: Mechanical system not responding or out of adjustment — see the full FMI reference table.

On a Caterpillar display this code may appear as MID/CID 102 with FMI 7, or in the older PID/SID style. Wording of the reported detail follows the public Caterpillar fault-code listing cited below.

First checks (general, for this failure type)

The system is not responding mechanically. Check linkages, actuators, and for hydraulic or mechanical blockage before replacing electrical parts.

These are general electrical checks for FMI 7 faults, not a substitute for the model-specific test procedure. If the fault is active and the machine is derated or shut down, follow the service manual for your model and serial prefix.

Need the part?

If the checks point to a failed sensor, solenoid or harness part, send us the code (102 / FMI 7), the machine model and serial number — we quote genuine and OEM replacement parts for export.
