Fault code and values

Hi guys,

I have two fault codes, one is the evaluator solenoid I think.

P0443 purge valve circuit fault. I guess this is because the solenoid isn't connected to pin 47. Does anyone know what the resistance of the solenoid is? So I can fir a resistor etc.

Other fault is.

P1474 FCLOW primary circuit malfunction. Not sure what this is??

Zetec Black Top ECU etc.

Cheers!!!

I have a little bracket behind the dash with one of these for the purge valve eBay Item

I’ve never seen one for the low speed fan control, have you tried to connect anything to it ?

Hi ya,

For the purge valve, guessing that a 5w bulb? I can frig that with a resistor etc.

Will have to look at schematic, not sure what pin would go to cooling fan relay?
