Do both fans work for sure? You may want to replace the fans runs anywhere from 140$ up to 250$ depending on the brand.
Keep me updated.

This code is generally for the fan. It could be a loose or broken wire or it could be that the fan is going out and not working on a regular interval or coming on at a higher temp then it should.

These cars have problems with the magnet falling off the cam gear it is just glued on and will often start to seperate. usually this results in a "Hard code p480" and the only drivability problem would be a slightly longer crank time and the injectors will not fire sequentially anymore. It could also possible sugjest a timing chain that is sloppy, if the chain actually slipped it would probably strip of gear teeth and it would not be an intermitant problem. I sugjest that you start by having the cam sensor signal tested or if you have a LabScope yourself Test the waveform generated by the sensor. Look for drop outs or a low amp out-put signal.

Hope that helps

Sir,

There are three types of issues that will set a code and two that will turn on the light. Your shop will need a very good scanner, an enhanced scanner with OEM Ford software, one will set a code inone driving trip but will not turn on the light. A problem in two trips will turn on the light BUT if the problem fixes itself then the light will go out on its own. There is a history of the problem stored in the computer scan data, it is called a freeze frame. If the catalytic convertor is in danger of being damaged then the ceck engine light will come on and usually flash, when that problem goes away so will the light. Freeze Frame scan data, get it checked out by a real shop with an OEM enhanced software scanner. It does not have to be the dealer, make some phone calls and go to the best shop, yes they may also charge the best (for them) price.

Thanks
Good luck
