Erase CODES?
Error code: (17511) O2 Sensor Heating Circ.,Bank1-Sensor1 Output too Low
I Changed both O2, Before and After Cat. O2 sensors because both looked jacked....
After replacing sensors, a few days later check engine light came bck on.
I checked if everything was connected correctly and tightned everything......few days later, Light check engine light came on again with same error......tried taking battery off for about and hour, still the same.....any ideas?
