Review on Enhance Performance and Efficiency with Denso 234-9063 Air and Fuel Ratio Sensor by Trevor Blazis

Revainrating 5 out of 5

Fixed 2007 Civic Hybrid

Exactly matches the original primary oxygen sensor in my 2007 Honda CIvic Hybrid. The check engine light came on (CEL codes P2A00 and P1172), my summer mpg steadily dropped from +60mpg to 55mpg (that's per tank), a new sensor and I was back in the 60's with no CEL. Before you begin, make sure you have purchased/rented/borrowed a 22mm oxygen sensor socket. I'll be posting a DIY thread on cleanmpg.com soon.

Pros
  • Sensors
Cons
  • Slightly torn
