Furnrep101 Posted March 15, 2007 Share Posted March 15, 2007 One of my previous posts was regarding oxygen sensors which I had installed on my vehicle in Sept. 06. This was for the sensor which is located underneith the vehicle and comes through the floor board. Since then my check engine lights have come on again so I had it checked out. Now I am getting 2 errors when read by a vehicle scanner.. P0031 HO2S Bank 1 Sen 1 Heater Circuit Low(which I think is the same one I received last time) and a new one P0037 HO2S Bank 1 Sen 2 Heater Circuit Low. I have driven about 18k miles before the lights came on again. Any thoughts? Thanks. Quote Link to comment Share on other sites More sharing options...
