Hello and Welcome to justanswer..

This fault code is down to the EVAP ( emission control circuit ) I have diagnostic info I can give you on this.. You may we need shop help - but here is the info for you below : Any good shop will be able to work through the following for you ..

 

Evaporative Emission Control – P0443

Complaint:
Fault code P0443 will most likely be set due to an EVAP purge control in the valve circuit fault.

 

 

CHECK EVAPORATIVE PURGE VALVE INTEGRITY

  1. Disconnect the outlet pipe from the Evaporative purge valve. (From valve to manifold).
  2. Apply a vacuum to the valve outlet pipe.
Does the valve hold vacuum?
Yes

Possible intermittent fault. CLEAR the DTC. Carry out a full EVAP system monitor drive cycle. RECHECK DTCs. For additional information, see 'diagnostic drive cycles' above.

No
INSTALL a new Evaporative purge valve. CLEAR the DTC. Carry out a full Evaporative system monitor drive cycle. RECHECK DTCs. For additional information, see 'diagnostic drive cycles' above.
