NEED HELP AGAIN, 3rd gen MAF Options

[Lil-Joe101]

Where is the MAF sensor on the 3rd gen 3sgte and anyone help me here. Pics would be greatly appreciated.

Here it's labeled as the turbo pressure sensor:

Thanks Box. I got code 31 and 52 today while driving, how do they corridinate or affect each other? 31=Air Flow Signal (Vacuum Sensor Signal), 52=Knock Sensor signal My knock sensor is brand new which leaves me to believe that its setting a code due to the failing Air Flow Signal which I want to say is being caused be a bad MAF or in a 3rd geners case turbo pressure sensor. Am I right in believing this?

The car doesn't have a MAF, it has a MAP. More or less they perform the same function, just different ways of doing it. But a bad MAP can throw off the air/fuel ratio which could cause pre-detonation which would trigger the knock sensor. It's a MAP, they just labeled it as the turbo pressure sensor. Which in a way is true as the MAP measures the air pressure inside the intake manifold. Where as a MAF measures the incoming air flow and is between the air filter and throttle body.
