replaced both upstream sensors due to bank 1 sensor 1 low voltage and bank 2 sensor 1 high voltage.
replaced the bank 2 about a week ago and cleared the codes and bank 2 never came back but obviously bank 1 was still there (p0132).
replaced bank 1 sensor 1 today and now I get a pending p0135.
could it mean my o2 sensor chip in my computer is fried?

 

Usually it would be the wrong sensor, bad connection, disturbed wiring, etc.
