i have a 07 f250 psd with about 70k miles on it. i have k and n intake and filter. it's throwing code p0098 air intake sensz circ high. wondering which sensor this is, and if it's a part to get from k and n, or ford? and if there's anyways to test it?
thanks

 

You have two intake air temperature probes (IAT1 - is part of the MAF sesnor) and the downstream IAT2. Your IAT2 may have a short to ground.

 

where is the iat2 located and how to test. or should i just replace?

 

the iat is next to the fuel/oil filter housing. its a 2wire grey connector. to test it I would look at pid values iat1 and iat2 when cold. most common is caused by a broken connector and it is no longer seated correctly.

 

thank you, i found the iat2 and the connector was just a little loose.

 

no problem
