I just got the codes pulled. I get the following;
17965 - charge pressure control: positive deviation P1557 - 35-10 ---
intermittent
17547 - fuel trim: bank 2 (add) : system too rich P1139 - 35-00 - -
(and 17545, which is the same as the last one, but for bank 1)
I'm told the first one is about the purge valve (which lets gas vapors
from the tank into the intake air.
I'm told the second two could be either the forward O2 sensors, or the
MAF sensor. I'd say more likely the MAF than 2 O2 sensors at once, esp
at 54K miles.
What is the procedure for MAF coverage, if that turns out to be a problem?
Thanks!
David
