This Denso 234-9017 Air - Fuel Ratio Sensor was the ...exact part needed to get rid of the DTC code P0135 (Heater Circuit Failure) on a 2004 Honda Civic Ex 1.7L Sedan. 15 minutes to change out, reset Check Engine Light, and all is well now. Price is a steal, as compared to any of the Big Box Auto Parts Stores. They wanted upwards of $225 for exactly the the same part. Shipping was very prompt - received part a few days before it was expected. No complaints at all, 5 star part, 5 star shipping.
