Have an 06 gt and my service engine light came on and my O2 sensor was reading high voltage. I replaced the O2 sensor and it came back on so I replaced the other one and still came back on.(I have long tube headers). I can not get this light to go off. What could it be?

Anybody?

Did u get the code right after the headers were installed? Do u have a tune?

mustangmike06

I have a tune and have been running the headers over a year now, the code is P0152 high voltage b2s1

I get those codes everytime I use poor quality gas. I have a 93 octain tune, high flow cats and flowmasters and a cia. I have to get my gas from shell but if I get if from like 76 or some other place with not so great quality ill get those codes. Just experiment with diferent gas stations, but try shell first and see if it goes away. Also make sure ur putting in the right octain, I'm sure u know to do that.

I have a CAI, LTH, off road H, and a bama 93 octane tune. I always fill up with shell 93 or Bp 93. I just don't know what it could be?
