  1. P2453 Diesel Particulate Filter Pressure Sensor A Circuit Range/Performance Medium

    The P2453 code means the diesel particulate filter pressure sensor gives a reading that is electrically valid but does not match what the computer expects. The computer cannot calculate the soot load or decide when to regenerate. Drive with caution, because the filter may not regenerate.
