P2474

Symptoms

Possible

Check Engine Light illuminated (or Service Engine Soon warning light)

P2474 Meaning

The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out-of-range high values. The EGTS is located upstream of the Diesel Oxidation Catalyst (DOC) and/or upstream of the Diesel Particulate Filter (DPF). The EGTS detects exhaust gas temperature and converts it to voltage, sending it back to the PCM with the voltage signal to control engine conditions for effective emission reduction. The PCM sets OBDII code P2474 when the Exhaust Gas Temperature Sensor is outside factory specifications.
