Code readers.. What do these codes mean?

[98T/ACOBRAEATER]

ok. i have a actron obd 2 autoscanner and my check engine light is on and these are the codes its bringing up but im not exactly sure what they all mean.


O2 SENSOR CIRCUIT LOW VOLTS (BANK 2 SENSOR 1)

O2 SENSOR CKT SLOW RESPONSE (BANK 2 SENSOR 1)

O2 SENSOR CKT NO ACTIVITY (BANK 2 SENSOR 1)

O2 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)

O2 SENSOR CKT NO ACTIVITY (BANK 2 SENSOR 2)


WHAT IS CAUSING THESE CODES?

I DID MODIFY MY EXHAUST.. LONG TUBES, SLP RESONATER, MAGNAFLOW HIGHFLOW CAT ALL 3 INCH. I WANTED TO KEEP ALL THE EGR CAUSE I FIGURED IT WOULD BE CHEAPER TO JUST BUY THE O2 SENSOR EXTENDERS AND JUST PLUG THEM BACK IN SO MY CHECK ENGINE LIGHT WOULD STAY OFF BUT OBVIOUSLY SOMETHING ISNT RIGHT...

Bank 2 sensor 1 is teh passanger side pre cat sensor. look like it is not working, chek your wiring and replace the sensor. Thr last one is the post cat sensor and cen be tuned out.

check to make sure your passenger side front sensor is plugged in. if it is replace it. you can get the back sensor tuned out or get o2 eliminators for it.

ok so how do i get the rear sensors tuned out? just buy a tuner? or buy the eliminators? where do i find eliminators oklahoma doesnt sell them in speed shops its illegal.

Any dyno shop can remove the codes and disable them. Send a PM to a memeber by the name of FROST, he can help you out more and he does mail order tuning.
