No, they work on the rear o2 sensor and this code is from the front. Check your fuse box and see if a fuse wasnt blown. If not then just get you too new sensors. Im sure they havent ever been changed before so get two new ones from the front, or upstream sensors. Look at them and make sure they are connected correctly and not burnt agaisnt the exhaust.
