Code P2A00 Honda Description

The Air/Fuel ratio (A/F) sensor has a linear signal output in relation to the oxygen concentration. The Powertrain Control Module (PCM) computes the air/fuel ratio from A/F sensor output voltage and uses the fuel feedback control to improve exhaust emissions. The PCM monitors A/F sensor output voltage during deceleration with the throttle fully closed, and if the output voltage deviates greatly from normal oxygen concentration levels, it detects a malfunction and stores a Diagnostic Trouble Code (DTC).
