Default FF37 - no listing for V12?
Tonight on my 94 V12 the check engine light came on and the screen indicated FF37 and FF44. I looked all through the manual at the FF code listings and there are none for the 6.0 that I can see. Any ideas what it might be?

The 4.0 sedan DTC for FF37 is the EGR vacuum solenoid circuit fault. I don't know if it is also for the 6.0.

TSB for FF44

As far as I can tell, no EGR on the 6.0. I have already done the TSB for the O2 sensors when I got the car. That's why a FF37 has me puzzled!
