just had the 4 o2 sensors put in and had 12 fault codes out and now after the 4 put in still have 4 codes. they are:po135 pd 01/04--po141 pd 02/04--po155 pd 03/04--po161 pd 04/04. can anyone shed any light on this problem? the lite goes out when i cler the codes but the check engine lite comes on after about 1/4 mile. and the same codes come back.

First thing I would do is check the fuse under the hood. I believe it is fuse number 11 that controls the heaters in the O2 sensors. It is what is called a Maxi-fuse (bigger ones). If that is OK, then I would look at the wiring. All those codes deal with the heater circuits in all 4 O2 sensors. Good luck and let us know. Being way2old is why I need help from younger minds
