I have a 2009 Challenger SRT8 with magna flow exhaust, headers, supercharger an cant get my O2 sensors to pass after installing a new battery. I have 87 warm ups since cleared, over 1000 miles driven and all my )@ sensors are showing voltage be 0.0 and 0.9 cycle. I'm showing no codes. Any suggestions? if a senor is bad, I get a code, correct? Could it be possible that I have sensor(s) bad causing my problem but not getting codes?

 

First, wrong section. Challenger doesn't even remotely resemble a truck.....

Second, what is the actual problem? Not real clear from your post.

Third, O2 sensor return signal will fluctuate between zero, and 1 volt. That's normal.

 

If you need to replace the 02 sensors buy a good brand name one, like Bosch or Mopar. don't go cheap when it comes to the electronics.

 

Skip bosch as well. Mopars just don't seem to care for them. NTK, or Denso only please. (both OEM manufacturers.)
