Fault meaning and symptoms
The document defines fault code 2961 as Exhaust Gas Recirculation Temperature – Data Valid But Above Normal Operational Range – Least Severe Level. The exhaust gas recirculation (EGR) temperature sensor is a variable resistor sensor and is used to measure the temperature of the EGR gas flow after it exits the EGR cooler. The condition is monitored on SPN 412, FMI 15, and is annunciated with no dashboard warning lamp. Documented causes in the Shop Talk section include plugged or restricted egr differential pressure sensor ports, damaged egr differential pressure tubes, a malfunctioning egr valve. Each fault is worked with the INSITE electronic service tool, cross-referencing associated procedures 008-018, 010-080, 011-019, 011-027, 019-032, 019-370.
Applicable truck models
This procedure covers Cummins ISX11.9 CM2250/ISB6.7 CM2250/ISC8.3 and ISL9 CM2250/ISX15 CM2250 engines built for the 2010-12 on-highway emissions platform, so it suits Class 8 trucks and vocational chassis running these engines. Confirm the exact application and current calibration against the official Cummins website before ordering parts.
Who needs this fault code 2961 DTCs manual
Diesel technicians and workshop owners who read 2961 on the INSITE service tool use this manual to follow the factory-approved diagnostic tree instead of replacing parts by guesswork. It is equally useful for fleet maintenance staff verifying a repair before returning a truck to service.
