Cummins fault code 472 circuit description
The crankcase oil level sensor is used by the ECM to monitor the lubricating oil level. The ECM monitors the voltage on the signal pin and converts this to an electronic value. The oil level value is used by the ECM for the engine protection system. Low voltage can be caused by an open circuit in the signal wire, a short circuit to ground in the signal wire, a short circuit to ground of the supply wire, an open circuit in the supply wire, or a faulty sensor. High voltage can be caused by the signal wire shorting to another wire in the harness, The ISM CM570 diagnostics in this file are indexed as PID S017, SPN 1380 and FMI 2/2, so it slots directly into the wider set of ISM CM570 fault codes on the platform.
Applicable truck models and engines
The procedure applies to Cummins ISM, ISX and Signature engines built on the CM570 (1999-02) electronic control module, fitted to a wide range of Class 7 and Class 8 on-highway trucks. Because component locations vary by chassis, the document repeatedly directs the technician to the OEM troubleshooting and repair manual for exact positions. Verify engine and calibration data against the official Cummins engine support resources before ordering parts.
