The Cummins M11 115 sheet documents the engine position sensor circuit (PID P190, SPN 190, FMI 2) on Cummins CELECT engines built from 1990 to 1994. This 7-page reference drives a technician through the circuit description, engine position sensor location, and the pin-by-pin checks needed to turn the red lamp off.

Applicable truck models
This procedure applies to Cummins M11 CELECT engines built from 1990 to 1994 and shares the engine position sensor logic used on N14 CELECT engines of the same era. It is a fault-code troubleshooting sheet from the CELECT diagnostic set (SRT 00-081), 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 115 diagnostic steps
Clean the sensor connector with electronic contact cleaner Part Number 3824510, then check each engine position sensor pin for a short to ground above 10M ohms. Remove and inspect the sensor for metal debris or camshaft damage, and measure the coils — pin A to D and B to C read 1000 to 2000 ohms, while A to B reads above 10M ohms. Verify the harness pinout (red to D-14, black to A-11, white to B-15, green to C-1) and check pins 1, 11, 14, and 15 for shorts, monitoring cranking rpm on the diagnostic tool.
Who needs this Cummins M11 115 manual
Technicians facing a no-start with no rpm signal use this FMI 2 sheet to confirm the engine position sensor, its coils, and harness pinout against factory values before condemning the ECM.
