I got this O2 simulator to replace a bad O2 sensor, but I went ahead and replaced the sensor instead. This sim can be used to replace the signal from a heated O2 sensor for whatever reason (bad sensor, test pipe, etc) to eliminate annoying CELs.

I paid $52.99 plus shipping, looking to get $50 shipped (plus paypal fees or send as gift). It is new and never installed. Exact same as the one here http://www.amazon.com/Oxygen-Sensor-...6936181&sr=8-5
