This document is a Cummins fault 2964 diagnostic troubleshooting sheet for the ISB6.7 CM2150 engine family and related CM2150 DTC coverage. It explains Fault Code 2964, where intake manifold 1 temperature is valid but above the normal operational range, least severe level. The file is useful when confirming whether the issue is a real high charge-air temperature condition or a failed intake manifold pressure/temperature sensor.

Who needs this Cummins fault 2964 manual
Workshop owners, diesel mechanics, and fleet technicians need this fault 2964 manual when an engine derates because the ECM detects intake manifold air temperature above a calibratable engine protection warning limit. The document supports checks with INSITE™ electronic service tool against a mechanical gauge or known value before deciding whether to follow the intake manifold air temperature symptom tree or replace the sensor.
