Help deciphering ABS fault codes
 

Recently, my ABS / traction control lights go on whenever I drive. I replaced all four ABS wheel sensors and cleaned the geared teeth near them. I also replaced the two ABS relays, checked the fuses and cleaned the electrical contacts for the ABS computer. Unfortunately, that did not fix the problem.

I had a local shop scan for codes, and they said there were three:
(1) Throttle valve actuator faulty
(2) Wheel speed sensor L/R faulty
(3) Pedal travel signal faulty

To fix problem #1, I think I need to buy part 35-41-1-163-163.

To fix problem #3, I think I need to buy part 34-33-1-182-594.

Have I already fixed problem #2, and this was an old code?

I own a 1994 325i (M50 engine). The last seven digits of the VIN is FM10118.

This appears to be a $500 fix, so I want to make sure I'm correct with the parts. As always, thanks to all your advice in advance.
