SOURCE: 2008 Chevy Trailblazer Error codes B0455, B0131,

{: ) If your vehicle is equipped with an air suspension system, one possible source for this combination of codes is the wiring along the air compressor located on a bracket on the left rear chassis frame, near the spare tire. Carefully pull the plastic conduit off of the wires, and inspect the wires for any cuts / abrasion or possibly a resulting corrosion (due to a short or open circuit & water exposure)

SOURCE: Replaced air check valve and air pump 06 trailblazer 4.2 and error p2431 came back any help would be appreciated

The problem could be a connector, the wiring, or the sensor that is built into the solenoid valve mounted on the exhaust manifold.
The solenoid is a dealer part.
You may need a dealer mechanic with a scanner to track it down.
