ok, so ive been having problems with my 02 sensor, i bought a bran new one from work (Advance) put it on, and it wasent sending any voltage to the ecu, so it was throwing a o2 code, i got another sensor, it worked fine, now 2 months later, its now throwing the code, and no sending a signal to the ecu. they are BOSCH sensor, is it the sensor? or mabey my car is hard on o2's

i use a proram hooked to the car, thats how i check ecu codes, and i can read o2 sensor voltage, the sensor is dead


its a NTK sensor, or thats what is stamped on it, its sold as a bosh thoguht, i know NTK is NGK o2 sensor





ok im also having a problem with the rear right abs wheel sensor, do they just go bad? or wtf happens to them? its def not working, its clean and the abs ring is lined, up.

 

ABS sensors fail for any number of reasons.
the o2 sensor usually has a reason for failure. I would check the wiring as bosch uses a MUCH longer than needed wire for it. more places for it to get nicked and short itself out.

 

I've had nothing but good results with my Bosch replacement O2 sensor from Advance Auto. I agree that the wiring is longer than needed. Make sure it's wrapped neatly and tied off properly. Another hint: double check the electrical connector and make sure your power steering hose isn't dripping oil on to the connector or wires. If you have never replaced this hose on a car this old, it's possible that this could cause a problem. Having two O2 sensors go bad in that short a time isn't normal. I'm sure it's not the parts...you'll have to keep troubleshooting until you find out what's causing them to go bad.
I would also suggest bypassing your "program" and pulling the codes from the ecu to confirm both are in agreement.
