DTC codes / P24xx · Auxiliary emission controls / P246A
P246A indicates that the powertrain control module (PCM) has detected an intermittent or erratic signal from the exhaust gas temperature (EGT) sensor located after the diesel particulate filter (DPF) on bank 2 of the engine. The PCM monitors this sensor to protect the DPF from overheating during regeneration, and when the signal jumps or drops out unpredictably, it sets this code and may disable regeneration.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
