I have a acura 1997 cl 2.2 I'm getting this code on my scanner p1108 baro high circuit

Here's where things get weird.
On your car, that code more often means the Powertrain Control Module (PCM) has an internal fault. In other words, the PCM has failed and will need replaced with another.

This is the fault trace procedure:

31902

Have you done the reset on your PCM?
