Review on Denso 234-9052 Air Fuel Ratio Sensor: Enhanced Performance and Precision by Brett Kolpack

Revainrating 5 out of 5

Ideal for spare parts

This was the perfect replacement and direct replacement. It was a factory part. I replaced it with a 2008 Toyota Corolla S. This particular vehicle is too close to the firewall to use the sensor socket, so save your money. Remove the heat shield, disconnect the sensor and use a 22mm combination wrench (box spanner). Pro tip: I didn't have a 22mm and none of the locals had one. The 7/8 wrench was close enough to get the job done without damage. And the man was an old ignorant that came out.

Pros
  • Easy to use
Cons
  • I vaguely remember
