Hello all!

Check engine light came on thursday night. took it in to dealer friday morning.

tech entries:
fuel evaporation system-test, perform
control unit- software (after short test), install
control unit-..... code (after short test), perform
perform star diag found codes 1085(po455), 1600(p0071).
perform fuel tank
perform control module reprogramming & scn coding. now ok

dan, can you tell me what those codes mean?

so i drive home and then as i get near home, the check engine light comes on again.

smoke is now coming out of my ears as blood pressure rises.

i return to dealer this morning. get a service rep and technican that are more knowledgeable. (roof module deactivated as was 3rd brake light flasher)
here are the notes:

customer states check engine light has come back on see history attached
electrical fault erratic signal from b14 outside temp sensor while driving
short test, perform
test program - after short test, perform
air cleaner, r & r (my note, fyi, sport filters installed)
sam control module - left side engine compartment, replace
(a electrical system, test / determine condition
outside temperature display sensor, repl. (after test)
eng. compartment panel, bottom - front part, r & r
short test, code p0071 (my note, apparently first tech, while getting both codes, only fixed one!!!!!) performed readings of actual values/test after
test, printout. r/r air cleaner, inspect intake/maf sensor & connection, clean
& tight. r/r drivers sam perform elec test to conn 1 pins 1 & 2 of b14
found erratic reading 18k ohms. r/r eng compartment panels, replaced b14
outside temp sensor. road test 10 miles & cycle key 10 times verify concern
remedy and short trest again, no codes present now.

**** apparently there is a new software recall out****
campaign
battery charger connect (with sds connected)
start diagnosis system (sds), connect & disconnect
engine control unit software check (with das connected)
performed repair # 1 of campaign

So i am posting this issue as an fyi that where i just thought the outside temperature probe and display was just to let you know the outside temp it also works with the engine computer in the mixture of fuel (as it was explained to me in layman's terms)

I am glad my 2nd tech was more knowledgeable to catch the 1st tech's omission of the code.

Hope the light stays off! have a nice memorial day for those in the states!
