Code P0106 Not Boosted

Thesmoke90

My car threw a P0106 when my throttle bodies were dirty (40k Miles)

The actual code might suggest there is an issue with the manifold, but really it can be caused by the throttle bodies prematurely shutting at stops due to gunk and buildup. This creates an 'unexpected' amount of air coming into the manifold, and that can cause this code.

Take a look at the backside of your throttle bodies. Cleaning them is pretty easy, there are a lot of videos on it. Biggest trick to it: disconnect your battery before you start, and do not remove any wires or couplings to the TB from the car. You only need to remove the 4 alan screws on each side to get a good look at them.

The code went away after a while, but after cleaning the TBs, the car idles much nicer now.

Could be unrelated, just hope this helps in some way.
