I just bought 99 millenia in PA from a dealer he gave me the car with 6mo
nths eagle warranty its giving P170 (fluid trim malfunction bank-1,P173 (
fluid trim malfunction bank-2 and P1526 (manufacturer speed control and auxi
lary input) I donno much about the cars, The dealer gave me the car wit
h no cel even on modeII (before starting the engine) he says the bulb is
shot I just found that trany is leaking from the transmission and also th
e front wheels move because of the faulty ball joint control arms

Then I took this car to the dealer back and he said he cant gimme the warran
ty and also the repair then at last he agreed on fixing it after forfeiti
ng the six months warranty, and fixed the CEL bulb. its been ten days, and
dealers mechanic says that the leak was because of the leak from one of the
valves, and he tightened some screw, and fixed the leak I am not sure if
he is right!! can you please tell me what those codes exactly means (what exactly are left and right bank trims)

 

P0170, P0173 Fuel Trim Banks 1&2... I have had the same issue. This was the little 'T' connector on the vacuum line located between the ABV and Supercharger. Takes about an hour or soto replace. It's a plastic connection for $1.50 at Napa. I would opt for a metal one instead ($3+).
