I pulled some codes off car 2002 4dr 2.7 6

p1192 - intake air temp volts low
p01493 ambient battery temp sensor volt low,
p0405 EGR valve position sensor circuite signal low,
p0117 electonic coolant temp low volts,
p0122 throttle position sensor low volts

My question is what controls all these sensors with power for all of them to be on at the sametime? any help would be great thanks

 

5 Volts from the Power Control Module.

 

bad battery or alt

check output on alt and bat

check fuses and grounds
