Cummins ISM code 692 is the DiagTechPro reference page for this Cummins diagnostic fault code 692 document, a 5-page PDF sourced from TruckFaultCodes.com (Copyright 2017) covering the lamp: amber turbocharger 1 compressor inlet temperature sensor circuit – voltage below normal, or shorted to low source isx – condition. The turbocharger compressor inlet temperature sensor is a variable resistor sensor and is used to measure the temperature of the air entering the compressor inlet of the turbocharger. The electronic control module (ECM) supplies 5 VDC to the compressor inlet temperature signal circuit. When the condition is detected the ECM logs the fault and illuminates the amber warning lamp.

This document applies to Cummins Turbocharger Compressor Inlet Air Temperature Sensor Circuit ISM – Turbocharger Compressor Inlet Air Temperature Sensor Circuit electronic engines in the ISM CM871 (2007-09) family used in on-highway and vocational trucks. The turbocharger compressor inlet air temperature sensor is located in the compressor casing of the turbocharger. Verify the electronic control module (ECM) calibration is correct. If necessary, recalibrate the ECM. The troubleshooting section walks through connector and pin inspection, circuit measurements and step-by-step checks, then confirms code 692 is inactive before all fault codes are cleared. Verify engine calibration and coverage against the official Cummins engine support site before ordering parts.
Who needs this Cummins ISM code 692 manual
Any mechanic or workshop owner diagnosing ISM code 692 needs this PDF to follow the factory diagnostic steps in the correct order and avoid replacing parts that are still good. An extension harness between the main engine harness and the turbocharger compressor inlet temperature sensor can be used depending on the turbocharger arrangement.
