LBZ: Baro Sensor

[ikeG]

Where exactly is the baro sensor on a LBZ?

Inside the ECM.

Is it part of the ECM then? I called my local Chev garage and he said he'd got them in before. It came today and looks just like a MAP sensor?

LB7 and LLY it is hanging on the bracket that the bale connectors are mounted to, and it does look exactly like a MAP sensor. On the LBZ and LMM, it is inside the ECM, and it is not replaceable.

Josh knows what he's talking about cuz I just went through this today on a 2002 GMC LB7 and it def is under that braket with the bulkhead connectors on the older trucks . Sure wish I had dug this post up earlier today would of saved me lot of time.

Is there a way to clean it? I'm getting a baro code on my LLY.
