Angry multiple engine codes

I did the timing belt/waterpump/valve refresh this past winter. After completing the task I started getting engine codes. Everything kinda pointed to a vaccuum leak but I couldn't find one. There is a pattern to the codes being tripped but it just doesn't make sense. Just wondering if anyone else has experienced this problem. The engine codes that keep repeating are a combination of the following 3 codes:

1188 - Inlet throttle pressure sensor(which makes me think it's a vaccuum leak)

0551 - Power steering pressure sensor

0517 - Battery over temp sensor

A combination of any three of these codes will be tripped. Sometimes only one code, two codes, or all three codes. Always the same codes. I can erase the codes with the scanner and drive the car and the DTC will not trip. If I stop and turn the engine off then restart and drive it down the road, the code(s) will trip. I can stop, shut the engine off, erase and drive and the codes will not trip!

This is just too wierd! Any suggestions?

Well it sounds as if the comp doesnt catch it until the car has warmed up.
Just my assumption. So i doubt that its a leak

Well for the 0551 code check your PS fluid level first.

Ummm...hehehe...A little late but I guess I better post about what the outcome was. Basically, I said screw it and bought an entire new vacuum harness from the dealer ($75), put it on and "who'd a thought it" but that fixed the problem!
