The Cummins M11 141 sheet documents the oil pressure sensor circuit (PID P100, SPN 100, FMI 4) on Cummins CELECT engines built from 1990 to 1994. This 8-page reference drives a technician through the circuit description, oil pressure sensor location, and the pin-by-pin checks needed to turn the yellow lamp off.

Applicable truck models
This procedure applies to Cummins M11 CELECT engines built from 1990 to 1994 and shares the oil pressure sensor logic used on N14 CELECT engines of the same era. It is a fault-code troubleshooting sheet from the CELECT diagnostic set (SRT 00-087), not a full engine manual, so confirm exact wiring and part numbers against factory data on the official Cummins website before replacing any component.
Cummins M11 141 diagnostic steps
Confirm codes 123, 145, 154, 213, 222, 352, and 422 are inactive first, then clean and inspect the sensor connector with electronic contact cleaner Part Number 3824510. Install the oil pressure sensor breakout cable Part Number 3824775 and check the supply voltage (4.75 to 5.25 VDC) from pin A to pin B, then the signal voltage (0.40 to 0.60 VDC) from pin C to pin B. Check ECM pins 22, 7, and 13 for shorts and continuity, and use jumper Part Number 3822917 to verify ECM response.
Who needs this Cummins M11 141 manual
Heavy-duty engine technicians use this sheet to separate a failed oil pressure sensor from a harness or ECM fault, avoiding a needless sensor swap while protecting the engine protection system.
