P0443 Fault in 2000 Dodge Ram 1500 Van: Causes and How to Fix
The check engine light has activated on my 2000 Dodge Ram 1500 van, and the diagnostic trouble code P0443 is being displayed. What could be causing this issue, and how can I resolve it to turn off the warning light? Milton Reid
For a general understanding of P0443, see: http://www.obd-codes.com/p0443. The code indicates a problem with the evaporative emission control system circuit — this could involve wiring issues, blown fuses, or electrical faults. To permanently resolve the issue and turn off the check engine light, you must repair the underlying fault. Simply clearing the code will only provide a temporary fix; the warning light will return once the root cause is not addressed, and diagnostic data may be lost in the process.
