7.3L Powerstroke P1280 code

[1935 Ford Phaeton]

I have a 2002 Ford Excursion Ltd with 220,000 miles. I got an engine warning light and read it with my unit I got from Harbor Freight Tools(model 99722). It read P1280, ICP Circ out of range low. $10 (not sure what $10 means) Does that mean I need to replace a $10 sensor?

I think it means you've got a $10 scanner

And, unfortunately, they don't work on out trucks (they are not, strictly, OBD-II)

Next bad news, ICP is gonna cost you a Lot more than that (if you really need one...)

The light's ON so, Something's wrong, get it on a professional scanner maybe to know for sure what. In the mean time, go take a look at your ICP sensors plug and look for signs of engine oil that might have come from the sensor itself (they leak through as they fail)

if it is indeed the ICP, ebay has good prices as well as junkyards. where i live Ford usually was 3x what other dealers want.
