You're right sorry for the slip. I added the "C" out of habit. I also write
computer software ODBC is "Object DataBase Connectivity". Anyway I
understand the diagnostics acronym but I am not any closer to understanding
what the last code means.

I'll contact Acura.

Thanks,

Not "OBDC", just "OBD".

"OBD" stands for "On-Board Diagnostics". The version installed on your
car is #2, hence the acronym "OBD-II".

An error code itself is known as a "DTC", for "Diagnostics Trouble
Code".

Sort of. They are EPA-mandated, and are supposed to be the same between
all manufacturers and models. In practice, only the ranges are identical
(P03xx is always a misfire, P04xx is always exhaust-related, etc). But
the specific codes may mean slightly different things from maker to
maker.

P1xxx is a manufacturer-specific code. Honda does not use P1399, but
some other manufacturers do. You are consulting a list of manufacturer-
specific codes for some other manufacturer, not Honda.

If your reader is in fact reporting P1399 and no other untoward symptoms
manifest, then you need to have the codes re-checked by somebody with a
Honda-specific code reader, such as your dealer. Either you are
receiving a false report from a non-compatible reader, or the ECM is
defective. I lean towards the former.

I got a "check engine" light yesterday afternoon. I downloaded those four
codes from my ODBC II engine code reader. My book and software that came
with the reader both state that the codes "P0" prefixes are generic and
lists the descriptions. The last two are manufacturer specific. I searched
around on the net and found a listing here.

P1399 is listed at the bottom of the page.

According to my official Honda US-market OBD-II code list, P1399 is a non-
existent code. Honda does not use this code for anything.

How did you obtain that particular code?
