3.3TT JB4 GAUGES READING ISSUE

[BlackNightStinger]

ALL OF SUDDEN JB4 6 GAUGES NOT SHOWING ALL READINGS. MAP AND BOOSTER READING ONLY.
NO READING ON IAT,TRANS TEMP -40,GEAR.
ANY IDEA?

I had this happen to me before and the whole time I forgot to plug the obd2 back in from a trip to the dealer, but same for me only the map or boost was working when not plugged in to the obd2. Check your wiring as well I've seen some people have burnt or corroded wires because they rest on something hot in the engine bay.

YOU GOT IT. AFTER INSPECTION I FORGOT TO PLUG BACK IN.
THANK YOU.
