What year is the truck? This is a known "problem" where the sensor gets dirty or corroded and needs to be replaced. It's about $100 for the parts & time.

You might try removing the drain plug & shooting some carb cleaner in there & brushing it out with an acid brush. If you need to replace it, you'll need a new pig tail connector & gasket for the cover plate as well.

I'd also suggest that he get the IH replacement plug & check the HFCM on a regular basis (once a month or every other tank).

Depending you year & millage, it could be covered under warranty.

It applies to all years - it just depends on whether you're still in warranty of not.
