Code P244D Description

The diagnostic trouble code P244D indicates that the exhaust temperature in Bank 1 is too high for the particulate filter regeneration process to occur. In modern diesel vehicles, the particulate filter is designed to trap harmful particles emitted by the engine to reduce emissions. During normal operation, the vehicle's engine control module (ECM) initiates a regeneration process to burn off these trapped particles and clean the filter. However, when the exhaust temperature in Bank 1 is too high, the regeneration process cannot take place effectively, leading to the code being triggered.

  • HAD THIS ON A FORD MONDEO, WOULDNT ALLOW VEHICLE TO START AT ALL. FOUND THROUGH A DIAGNOSTICS MACHINE AND RESET EXHAUST GAS TEMPERAURE SENSORS. AS THE CAR SELF REGENERATION IN THE CATALYST CONVERTOR WAS TOO BLOCKED AND OVERHEATED THIS MADE THE CAR UN-STARTABLE. AFTER RESET OF THE SENSORS ALLOWED CAR TO START.
