The causes of code P2453, and indeed, all other DPF related codes are many and varied, but could include one or more of the following-

Damaged, burnt, shorted, disconnected, and/or corroded wiring and electrical connectors anywhere in the differential pressure sensors’ wiring harness
Defective, damaged, or clogged DPF
Defective differential pressure sensor
Clogged, restricted, or damaged exhaust pressure feed lines
Failed or failing PCM, but note that since is a rare event, the fault must be sought elsewhere before any control module is replaced
What are the symptoms of code P2453?
Common symptoms of code P2453 could include the following, but note that some symptoms of code P2453 and other DPF related codes could immobilize the affected vehicle until the root cause of the code(s) is resolved-

Stored trouble code(s) and illuminated warning light(s)
No start condition: note that on some applications, an out-of-range input signal from a defective DPF differential pressure sensor could be interpreted by the PCM as an excessively high soot load in the DPF. In these cases, the PCM may initiate a limp mode, or even disable the engine starting circuits to prevent damage to some components in the exhaust system
Some vehicles may exhibit varying degrees of power loss, with the severity of this symptom depending on both engine load and speed .
