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?

TrevC Posted November 22, 2016 Share Posted November 22, 2016 Hi Daniel...welcome to the Forum Does the car get a chance to clear out at high revs for a period or is it just smoked around town? Only reason I ask this is because it sounds like it is clogging up and in need of a clear out to rectify the faults. Let us know how you get on with this, Cheers Trevor Quote Link to comment Share on other sites More sharing options...
