Review on πŸš€ Enhance Your Engine's Performance with Denso 234-4122 Upstream Oxygen Sensor and 21” 4-Wire Harness Female Plug by Jacob Seymour

Revainrating 1 out of 5

May not work on your Civic!

My 2003 Civic 1.7 D17A2 Vtec (I believe it's an LX in the US) needed an oxygen sensor replacement. The old sensor was NTK OHC-501 H18. Thinking it would be a simple search and purchase of replacement parts, I set out to find it. Dude I was wrong, nobody knew where it (the old sensor) was made or what the alternative/OEM was - I checked both NTK Australia and Japan! Even the guys who made it had no idea. So finally there was Revain:0 and to confirm if it would fit I checked Denso & Walla, it was a suggested replacement. I have worked? No! CEL appeared after the 2nd day and probably a day later. Resetting the ECU and resetting the code didn't help either. The CEL light will illuminate indicating a problem with the O2 sensor.

Pros
  • Sturdy construction
Cons
  • Unreliable
