Code P2096 GMC Description

Fuel trim bias is used to keep the post catalyst air/fuel ratio within a predetermined range. This allows optimal catalyst efficiency under various operating conditions. The Engine Control Module (ECM) constantly monitors how lean or rich the fuel trim bias is commanded, to determine if the fuel trim bias is greater than a calibrated amount. The Diagnostic Trouble Code (DTC) will be set when the correction limit for a condition causing a rich or lean air/fuel ratio has been exceeded.
