Have you cleared the codes?
Do you have a factory service manual?
After you disconnect the neg cable to clear the codes (or pull the ecm fuse), start the engine and see if any codes return. If they do, then you will need a service manual to troubleshoot each code. That is where I would start. Search for vacuum leaks and double check all the wiring and connections.

The sensors you mentioned, have more than one trouble code.
Pull the codes and post the numbers.

You don't need a scanner, you need a paper clip to jump terminals "A" and "B" on the ALDL port.
