Cadillac Repair: auto, oxygen sensor, computer failure

Question
I have a 98 deville delegance and the codes on the dash are  pcm po132 po601,tcs c1278,mmm b2148 b2150,all of these codes says current what should i do about these problems and does any of these codes have something to do with my traction control light is on and my car kicks into hard gear.

Answer
P0132 = High circuit voltage in the oxygen sensor on Bank 1 sensor 1.

P0601 = Internal PCM computer failure.

TCS1278 = traction control system inhibited due to PCM fault.

B2148 = no such code.

B2150 = no such code.

You need to test ALL the circuits going TO and FROM the PCM computer before replacing it, Or you will most likely destroy the new PCM if you install it without testing the circuits first.
