What Cummins fault code 3382 means
Engine Exhaust Gas Recirculation (EGR) System – Data Valid But Below Normal Operating Range – Moderately Severe Level. Measured EGR flow is lower than commanded. Possible reduced engine performance. The manual explains that the electronic control module (ECM) uses the EGR differential pressure sensor reading to determine how much exhaust gas is flowing through the EGR connection tube to the intake manifold. The document lists the exact ECM conditions under which this code is set and cleared, so a technician can confirm the diagnosis with INSITE electronic service tool before replacing parts.
