P2453 Code: Easy Steps to Solve It
The P2453 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Diesel Particulate Filter (DPF) Pressure Sensor “A” circuit range or performance. This code is specifically relevant to diesel engines equipped with a DPF system, where the sensor monitors the pressure difference across the DPF to determine its efficiency and functionality. When the Powertrain Control Module (PCM) detects that the
