What is the actual code # being held in memory......if more than one, what order are they in?
I don't know why butI laughed my ass off when I read that, almost spit out my coffee.Check for pressurized air escaping on a turbo car like Ron White said.
I would do both and use the first code logged to guide me for the physical search for issues.In other words, always do the old school mechanic stuff first before hooking up the code scanner - check for vacuum leaks from cracked hoses, disconnected hoses etc. Check for pressurized air escaping on a turbo car like Ron White said. If you hear a ticking noise or knocking noise under the hood, use a mechanic's stethoscope to track it down. If you don't have one of those, use a short piece of garden hose and put one end on different areas of the engine while holding the other end to your better ear.
No; there's a mass airflow sensor (MAF) like any car on the intake side, and a manifold absolute pressure (MAP)/ turbo boost sensor in the pipe to throttle body.Aren't there a couple MAF sensors on this car? The only one I know of is the MAF that goes to the cold air intake. I cleaned it once using CRC MAF cleaning ages who when I was chasing a P0171 code. Turns out the issue was a small airline crack in the turbo air intake line. Another common point is the valve covers pressure relief valve failing. I've had both those at some point... meanwhile my dads 2009 Kia Sportage has had ZERO problems like this.
Got it thanks for clearing that up.No; there's a mass airflow sensor (MAF) like any car on the intake side, and a manifold absolute pressure (MAP)/ turbo boost sensor in the pipe to throttle body.
