77183, O2 Sensor Gone Bad? Posted by EclipseTenzoR, Jul-06-04 05:08 PM I am getting really crapy mileage and I'm led to believe that its the o2 sensor. I have read that the upstream sensor is one of the mail reasons for bad mileage. And lets just say I'm lucky to get 180miles on a tank. Would the 02 sensor be going even if I don't get a CEL? Also you guys ever hear of a brand called Walker? I was looking on Oxygensensors.com and they sell an OEM one for $54 made by walker.

IMO, stick to true OEM.
