My check engine light has been on with a P0138 High voltage code, bank 1 sensor 2. I replace the 02 sensor near the manifold (before the cat) as told to with a Bosch, but the light is still one, even after i reset the code it came back on. I checked my ground to the engine block which is good, and my 15A fuses look good to. Any other ideas as to why it getting high voltage, is the rear 02 sensor causing this and need to be re-placed? Anyone else with this problem figure it out?
thanks
