P0134 HONDA Description

  The air/fuel ratio (A/F) sensor is activated by warming the element with the heater and by maintaining it at a steady high temperature to calculate accurate air/fuel (A/F) ratio. The A/F sensor does not become active when the element is not warmed enough due to a heater malfunction, etc., and the exhaust emissions deteriorate. The engine control module (ECM)/powertrain control module (PCM) monitors the A/F sensor active condition by the A/F sensor internal resistance.
