Cummins M11 code 415 is the Cummins troubleshooting document for the Oil Pressure – Engine Protection fault (PID P100, SPN 100, FMI 1, SRT 00-057). The oil pressure sensor lets the ECM monitor lubricating oil pressure by converting the signal-pin voltage to a pressure value used by the engine protection system. It sets an engine protection or red warning lamp and lists the exact conditions, causes, and step-by-step checks a technician follows.

Trucks covered by Cummins M11 code 415
This procedure applies to Cummins M11 and 1994 N14 CELECT engines on 98M11 or 98N14 calibrations. The procedure carries the Cummins fault identifiers PID P100, SPN 100, FMI 1, SRT 00-057 for reference and repair-time tracking. It is set by oil pressure dropping below the engine protection limits, often when the engine is operated at too low a speed under load, and typical effects include engine protection action indicated by the engine protection or red lamp. For engine specifications and dealer support, see the official Cummins website.
Who needs this Cummins M11 code 415 manual
Heavy-truck technicians, fleet maintenance teams, and workshop owners diagnosing this fault use it to confirm the code before replacing parts. During diagnosis the oil pressure sensor supply voltage should read between 4.5 and 5.25 VDC at the sensor, and this fault applies to 98N14 or 98M11 calibrations only. The step-by-step tree starts by reading active and inactive codes with the diagnostic tool, then inspects the harness and connector pins for bent, corroded, pushed-back, or expanded pins, flushing them with electronic contact cleaner Part Number 3824510 before any component is condemned. Test leads run around the bulkhead are used to isolate a faulty OEM harness, and the code is rechecked and cleared once the repair passes.
