I replaced the sensor as was indicated by the code identified. I removed the old sensor. Thoroughly cleaned the tube it attaches to and installed the new sensor. About an hour later the code came back on. I then cleaned the old sensor with WD-40 and some q-tips and reinstalled it. Two days now and the code has not returned. I am still giving 3 stars as the service from the team there is second to none. Super fast shipping.
I am sorry to hear you ran into this issue during the install. We can definitely take the sensor back for you and submit it to the manufacturer for warranty. I am curious did you try reinstalling the sensor after you cleaned up the connections on the engine? If so it is likely that the sensor is defective. Either way we would be glad to reimburse you for your purchase if you ship the sensor back to us at:
