When is the Code Detected?

1. When the A/F sensor does not activate in a fixed time after the A/F sensor heater starts to warm up (within high A/F sensor internal resistance), a malfunction of the A/F sensor heater is detected, and a DTC is stored.
2. When the A/F sensor heater does not reactivate within a fixed time after the heater became inactive (with high A/F sensor internal resistance) from active (with low A/F sensor internal resistance) though the heater is ON, a malfunction in the A/F sensor heater is detected, and a DTC is stored.

  • Engine Light ON (or Service Engine Soon Warning Light)
  • High Fuel Consumption
  • Excessive Smoke from Exhaust

What Does the P0134 2010 Honda Accord Code Mean?

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.
