Are the front O2's different from front?

Like the queston saids....are they different and would they set off codes?....We installed headers and ORYP and we put O2 simms on the rear but I think we installed on of the original rear O2 sensor in front by accident...mainly because it was shorter and we didn't want them hanging down?.......Could that be setting the ses light?.......... :bang:

Re: Are the front O2's different from front?

Nope. Both pre-cat and post cat O2's are the same and can be swapped in order to find if you have a bad O2 sensor.

The SES light could be something totally unrelated. It could also be from something as simple as an exhaust leak if you didn't seal everything upon re-install.
