P0153 HONDA Description
The Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) has a linear signal output in relation to the oxygen concentration. The Powertrain Control Module (PCM) computes the air/fuel ratio from the front A/F sensor output voltage and uses fuel feedback control to improve exhaust emissions. The PCM measures the response characteristics against the front A/F sensor output, and if the accumulated value within the specified time is less than the specified value, it detects a deteriorated response and stores a Diagnostic Trouble Code (DTC).
