P2002 FORD Description
The Powertrain Control Module (PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM.
