Check Engine Light P0131 came on, Replaced o2 Sensor, then got P0135... eh?
So a few days ago my check engine light came on, and after that i pulled the code and came out with P0131-Primary heated O2 sensor circuit low/high voltage. looked it up and found out it's supposed to be a faulty o2 sensor. went to kragens and picked up a new o2 universal sensor from bosch, replaced it, and drove fine last night. this morning, I drove to class, and about 3 miles into driving, the check engine light came back on, and this time the code read P0135-Primary heated O2 sensor. this is the same sensor i just replaced. anyone have this problem happen to them before?
