Code P242F Description

The Powertrain Control Module (PCM) monitors the pressure decrease at the diesel particulate filter following a diesel particulate filter regeneration for a concern. The PCM calculates the amount of ash and the pressure increase the ash generates in the diesel particulate filter. During a regeneration the PCM expects the pressure to decrease. The amount of pressure decrease expected by the PCM is based on the temperature and flow of the exhaust gas. The test fails when the pressure reading at the diesel particulate filter pressure sensor does not decrease by the amount determined by the PCM.
