All,

I'm getting code dtc p2227 barometric sensor circuit range/performance and I'm in permanent limp mode. I cannot find it in the engine bay and googled for it's location but I can't find anything. Managed to find the part #12615136.

Where is the sensor located?

Thanks

 

Well i look this up on my p[arts catalog and it says this part number is for an LSJ, not an LNF

Do you have the part # for the LNF? Do you know where it's located?

Thanks

 

I think it's built into the ECM. It compares the value on the ECM to the values in the top MAP sensor and lower TMAP.

See this thread for more info:

^ What he said. The barometric pressure sensor is built in to the ECM on the LNF cars.

Why? No idea but its kinda retarted.

 

You didn't by any chance get the gmpp tune/sensors installed before this cel popped up have you?

 

Engine popped and dealership replaced piston#4, head and turbo. I had the gms1 sensors and all was well until after the rebuild.
