I found five codes:
1. Evaporative emission control system incorrect flow
2. PO446
3. PO420 (pd) Catalytic converter system efficiency below threshhold
4. PO441(pd) an. PO446 System vent
5. Control circuit
I already replaced the canister 9 months ago and the check engine light disappeared. Recently The check engine light disappeared but I still had "trac off' flashing occasionally and ABS stays on. Recently the check engine light has come back on.
Can anyone help me, please?
