Copmputer Codes

Recommended Posts

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?

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
