P2460 GMC Code - Diesel Particulate Filter Pressure Sensor 'B' Circuit Low
Quick Answer
The Powertrain Control Module (PCM) monitors the rationality of the Diesel Particulate Filter (DPF) pressure sensor during idle and part load operating conditions. Common causes include Faulty Diesel Particulate Filter (DPF) Pressure Sensor, Diesel Particulate Filter (DPF) Pressure Sensor harness is open or shorted, Diesel Particulate Filter (DPF) Pressure Sensor circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
