Smart aleky answer: Yes. You manually plug in the OBD II code reader into the port under the dash and manually read the problem displayed on the screen. If, by "manually" you mean the pre OBD II days where you jumpered a connection and watched a light flash on the dash the answer is, unfortunately, no. Systems have become far too sophisticated and you'd be counting Morse Code type long and short flashes for hours trying to figure out what the computer is trying to tell you. The good news is, OBD II readers are loaned free by many auto supply stores. In many cases you can grab the reader, plug it in in the store parking lot, read the code and walk right back in to purchase the appropriate part (which is why they loan you the gizmo for free).

Can you check Toyota check engine codes without special tools?
Depends on the year...if it's an OBD1 car (typically before 1996) you can manually access the codes and find out what they are by watching the "check engine" light blink. If it's an OBD2 car, then no...you have to have a code reader. The good news is that many auto parts stores will read the codes for you for free. Just be careful listening to their diagnosis.
