Keep the exhaust feedback loop accurate on your rotary with the DENSO Air / Fuel Ratio Sensor 234-9102. Mounted upstream of the catalytic converter, it reads the oxygen content of the exhaust and reports the air-fuel ratio to the engine control module, which uses that signal to trim fuel delivery toward the target mixture. It installs as a direct-fit replacement for the listed application: the 2004-2008 Mazda RX-8.

  • Upstream placement: positioned ahead of the catalytic converter to monitor exhaust gases as they leave the engine.
  • Closed-loop fuel feedback: continuously signals the air-fuel ratio to the ECM so it can adjust fuel delivery.
  • Direct-fit replacement: designed to install in place of the original upstream sensor on the listed application.

Signs this sensor may need attention include a lit check engine light, rough idle, or reduced fuel economy. These symptoms can have other causes, so diagnose the fault first; if a failed upstream air / fuel ratio sensor is the cause, this part replaces it.
