Diagnosing P2609 Code 5.9 Cummins: What You Need to Know

AvatarByCarl Frisch

The P2609 code 5.9 Cummins is a diagnostic trouble code (DTC) that is associated with the Cummins 5.9L engine. This code indicates that there is an issue with the camshaft position sensor circuit. The camshaft position sensor monitors the position of the camshaft and sends signals to the engine control unit (ECU). When this code is triggered, it indicates that there is a malfunction in the electrical circuit of the camshaft position sensor or that there is an issue with the sensor itself. In order to diagnose and repair this DTC, a technician will need to inspect and test the camshaft position sensor circuit and replace any faulty parts as needed.
