Cummins ISM code 135 is the DiagTechPro reference page for this Cummins diagnostic fault code 135 document, a 7-page PDF sourced from TruckFaultCodes.com (Copyright 2017) that covers the oil pressure sensor circuit. The oil pressure/temperature sensor is used by the electronic control module (ECM) to monitor the lubricating oil pressure. The ECM monitors the voltage on the signal pin and converts this to a pressure value. The oil pressure value is used by the ECM for the engine protection system. When the condition is detected the ECM logs the fault and turns on the yellow warning lamp to alert the driver and technician.

This document applies to Cummins ISM CM570 (1999-02) / DTCs; ISX CM570 (1999-02) / DTCs; Signature CM570 (1999-02) / DTCs electronic engines used in on-highway and vocational trucks. The oil pressure/temperature sensor is located on the engine block to the left of the fuel filter, behind the air compressor. The troubleshooting section walks through connector and pin inspection, engine-harness resistance measurements and pin-to-pin continuity checks, and ends with a road test that confirms the code is inactive and all fault codes are cleared. Because the same procedure isolates the sensor, the harness and the ECM in turn, it prevents replacing parts that are still good. Verify engine calibration and coverage against the official Cummins engine support site before ordering parts.
Who needs this Cummins ISM code 135 manual
Any mechanic or workshop owner diagnosing ISM code 135 needs this PDF to follow the factory circuit and resistance checks in the correct order. Does the fault occur only in cold weather? If so, allow the oil to warm up and see if the fault goes inactive. 2.
