Getting the above Toyota fault codes do not necessarily mean it is a serious or hard code. Sometimes it could be erased first and then re-tried again to make sure if the original code is permanent or not. A lot of the common Toyota OBD1 fixes are based on doing the basic engine maintenance requirements. Sometimes, garages are using the most common fixes available on the vehicles repair database which are usually stored in garages or vehicle's manufacturer's files.
