This troubleshooting procedure applies to Cummins ISX11.9 CM2250/ISX15 CM2250 engines. The EGR orifice pressure sensor is mounted on the EGR mass measurement assembly near the EGR differential pressure sensor. The document states the code is set when ecm detects that the egr orifice pressure sensor signal voltage is greater than 4.75-volts for 5 seconds. When the code is active, the amber warning lamp is illuminated when this diagnostic runs and fails. Full specifications and procedure references are published by Cummins on the Cummins official website.
