Hiya, I'm hoping you can help with a problem with my wife's 2015 1.2 petrol Skoda (is it a MK2, I'm not sure?).

 

The engine management light came on, so I bought a cheap code reader, which showed two codes -  PO443, and a similar one which said 'purge control valve short circuit' (something like that anyway) PO443 is 'evaporative emission system purge control valve circuit'.

 

I have replaced the valve, and reset the engine light. Unfortunately, after several miles, it's back on again. Only the P0443 code now though.

I reset and tried again, but the fault returned.

 

I'm hoping someone might know what to do next.

 

Any help appreciated.

 

Cheers.

 

Inspect the wiring that goes to it. And the connectors at valve and ECU end in case of water ingress.

Thanks for the response. I had a look at the valve end wiring, all clean and dry.

Where about is the other end of the wiring please, the ECU?

Yes, 1 wire does, the other appears to come directly from fuse 28, so it could well be worth checking that.

Engine code would help me check info better, Also look at characters 7 and 8 of VIN to see whether mk2 or mk3; the former is 5J. 

Wino, thank you sir. I have just checked fuse 28, and it was blown. Brilliant.

My next step was to take it to the garage, so I reckon you have just saved me a small fortune.

 

Very much appreciated.

 

Cheers.

Cool. Consider upgrading to  Freedom membership as a thank you to the forum, please. 

That's now done Wino, thanks again.
