2001 Dodge Caravan P0442 Code: How to Fix EVAP System Leak and Clear Check Engine Light
I own a 2001 Dodge Caravan Sport and recently received a check engine light triggered by fault code P0442. I replaced the gas cap, which is a common fix for this issue, but after driving it for several days, the warning light remains on. What steps should I take to permanently resolve this P0442 code? The EVAP system leak appears to be persistent despite the replacement of the gas cap.
P0442 indicates a small leak in the Evaporative Emission (EVAP) system. A 'smoke machine' test is often used to accurately locate the source of the leak. For more details, see: http://www.obd-codes.com/p0442
