There are some gauges that are pretty much just dummy gauges that don't get a true value from the sensor. The sensor may only be an on/off type, and in that case you won't be able to get a pressure or temp reading. Those same sensors may not feed into the ECU, and no OBDII reader will see it.
Check out this forum as they may have much more knowledge on the V10 specific PIDs. Make sure you have the extended PIDs downloaded for the Ford as well.
