didn't work on my mazda 3

as I said it didn't work. Installed it on my '08 Mazda 3 2.3L in an attempt to fix a bad O2 sensor after the catalytic converter. I know it's not because I scanned the car. After replacing them with them, the engine light bulb remained, and in addition, it had a negative impact on emissions. Now it is completely unreadable during scanning. Also, the connector wasn't holding in place, so I had to use a zip tie to securely connect the wiring harness. I just left it in place until I got the Bosch sensor. I will update as soon as I install Bosch

Pros
  • sensors
Cons
  • low maintainability
