P2452 - Diesel Particulate Filter Pressure Sensor A Circuit

Description: The powertrain control module (PCM) monitors the rationality of the diesel particulate filter pressure sensor during idle and part load operating conditions. The test fails when the diesel particulate filter pressure sensor signal value at idle is less than 0.15 kPa (0.022 psi). The test also fails when the diesel particulate filter pressure sensor signal value at part load is less than a minimum value or greater than a maximum value. These minimum and maximum values are based on the volume of exhaust.

Possible Causes: Diesel particulate filter pressure sensor connecting hose is loose, cracked, or missing
Diesel particulate filter pressure sensor connecting hose port is cracked or broken
Excessive amount of soot or ash in the diesel particulate filter
Damaged diesel particulate filter pressure sensor
