The Cummins fault code 3361 troubleshooting manual is the official Cummins procedure for diagnosing Intake Manifold 1 Pressure – Abnormal Rate of Change (SPN 102, FMI 10/10). The intake manifold pressure sensor signal is monitored by the ECM against engine operating conditions. This code sets when the intake manifold pressure sensor reading is not responding with engine conditions. The amber warning lamp behaviour and the exact conditions that set and clear the code are documented step by step.
