<LFC> lamp FAULT Code
 

Does any know what code 42 means on the LFC in dash

We need your vehicle info... year..model...etc

2004 fx4 with 5.4

I am not 100% sure, but if it is the same as the 2006 MY this is the LFC table ( again this is from a 2006 MY )

Looks like the front impact sensor has a fault.

When I compare the 2000 to the 2002 they are similar ( from what I looked at ) so it could be the same 2006 to 2004. DO NOT take this as a given.

Also, this is in the same area as the temp probe you asked about in the other thread. Have you done work in this area as of late ?
