Rawze sir

All my other sensors are working properly that are currently being utilized except the egr valve and now the egr temp. What was driving me crazy is the ecm shows pid 9 as amb tem sensor input pid at ecm but can’t find out where it goes.


At the vary least now I know what electrical tree branch if it were to look on. Seems all the temp sensors are in series on the same electrical line.
