Default Codes C0237, C0238 and C0239

ok. was clearing a code for a bad 02 sensor tonight at my local parts store, replaced the sensor, good to go. however, when i did a ABS system scan with teh scanner, it came up with 3 codes.

U1016 (loss of communications with PCM) i did a SES clear by pulling hte PCM and PCM ign fuses so thats explained.

C0237 TCS RPM Signal Circuit Malfunction
C0238 TCS Throttle Position Sensor Comparison Malfunction
C0239 TCS Spark Retard Monitoring Malfunction

What the crap is going on? is my TCS module Taking a crap? i cleared the codes and it felt like the car had an immediate 50 hp... and i'm NOT crazy...

i am thinking on pulling the TCS fuse(s) until i can figure this out... i am wondering if its pulling spark causing the loss of power. i did not notice the loss of power until the codes were cleared and it came back.
