I believe its maf insifficient signal. had the same code pop up on me. injuneer said 2 me 2 check the voltage in the mak adapter wires. a +12 should b in the pink wire. i myself have yet 2 do this, dont have a volt meter. but what i did was give it a good cleaning. since then the code never popped up again. hope this hepls. peace.

Mine did the same thing on my yesterday and I was getting current on the pink wire. I guess I will try cleaning it later.

My code was Mass Airflow system failure.

Same code for me today. Though I think it's cause I put too much oil on my filter when I cleaned it last week.
