CAN SOMEONE PLEASE HELP ME AND TELL ME WHICH SENSOR DETERMINES AND SETS THIS CODE.

 

are you sure thats the right code???
I cant find any valid codes even close to that??????

 

Mine set this one while I was unplugging injectors while diagnosing my knock.

 

yep. the code is a turbo under boost. checked all the hoses and cooler. no problem found. need to know what sensor sets it. thanks for the reply.

 

It could be one of two sensors. The one is the atmospheric pressure sensor in the intake tube. The other is the MAP sensor located on top of the intake maifold. Now that you mentioned this I remember having this code when my atmospheric pressure sensor came unplugged. You may just have to check connections on these two.
