2002 Dodge Grand Caravan P01684, P0442, P0455, P0456 - Evaporative Emission System Leak and Code Reset Guide

Model: 2002 Dodge Grand Caravan Fault Code: P0442 Posted: 2006-06-14 00:59

My 2002 Dodge Grand Caravan is showing fault codes P01684, P0442, P0455, and P0456, indicating a leak in the evaporative emission system. I've already replaced the gas cap, but I'm unsure how to reset these diagnostic trouble codes (DTCs). Can anyone provide step-by-step guidance on clearing the codes safely and accurately? Any help would be greatly appreciated.

To clear the fault codes, use an OBD2 scanner to read and reset the codes, or disconnect the negative battery terminal for 10-15 minutes to allow the vehicle's ECM to reset. Note that this method may not always resolve underlying system leaks—ensure the evaporative system is properly sealed before retesting.
