Applicable truck models
This file applies to Cummins engines listed in the extract, including ISX11.9 CM2250 and ISX15 CM2250 in the main Fault Code 213 section, plus GX CM2250, ISM11 CM876 SN, and ISZ13 CM2150 in the associated procedures table. The fault is identified as PID P175, SPN 175, FMI 4/4, with an amber lamp and no engine protection for engine oil temperature when active. The document states that the sensor is located in the oil rifle and that the ECM supplies 5 volts to the signal circuit while monitoring resistance changes to determine oil temperature. For manufacturer information, visit the Cummins official website.
Who needs this Cummins oil temperature sensor manual
Workshop technicians, fleet mechanics, and diagnostic tool users need this manual when Fault Code 213 is active or stored and the engine oil temperature circuit must be checked without guessing. It is useful for tracing a signal shorted to ground, a signal shorted to return, a damaged connector, a failed sensor, or an engine harness issue.
The procedure directs the user through fault-code status checks, connector inspection, sensor resistance verification, ECM connector inspection, circuit response checks, pin-to-pin short testing, and pin-to-ground short testing. It also references Procedure 019-067 for the Engine Oil Temperature Sensor, Procedure 019-043 for Engine Wiring Harness, Procedure 019-031 for Electronic Control Module, Procedure 019-032 for ECM Calibration Code, Procedure 019-360 for resistance measurement, and Procedure 019-361 for inspection techniques.
