Odd code, never ran into that one myself, if you clear the code and go out and drive it, does it come back? meaning is the code a hard fault? and triggers right away?

Wish I had a factory service manual to see what that code really means?... Fuel supply system, my guess is going to be something with an o2 sensor/fuel pump/injectors?

let us know whatcha find.

i've heard of a few people getting that code with no side affects as far as how the car runs. they have changed fuel pumps, injectors, 02 sensors, etc., and never gotten rid of the code, aslo referred to as the "bitch code" :P
