Review on 🔧 Upstream and Downstream Oxygen Sensors Kit - Fits Suzuki SX4 2.0L 2008-2009 - 234-9033 & 234-4165 by Jeremy Tang

On the good side: Both sensors fit, the threads and plugs were the right type. Low price. The bottom sensor works fine. Bad: The top sensor was not working. I checked the plug and the wires literally fell out of the sockets. I cut it off and plugged in the connector from the old sensor which solved the problem. Still getting OBD No Activity Detected Code. Put the old sensor back in and until it works again. It must have just been my downstream that was bad to begin with. The car was a '08 Suzuki SX4 2.0L.
