About this part

This Denso sensor sits ahead of the catalytic converter and reports the exact air fuel mix to the engine computer. The 234-9014 uses a zirconia solid electrolyte element with a built in heater for fast warm up. Denso describes it as highly accurate and built from durable materials, and it is the original equipment maker for this application. Common signs of a worn sensor include a check engine light, higher fuel use and a failed emissions test.
