SOURCE: High Idle
The Throttle screw is located on the throttle (obiously) its in a clinderical shaped channel located on the throttle just oposite or obliquely opposite the the throttle body position sensor. In some mazda vehicles (IN TRINIDAD) you need to loosen the throttle body position sensor and slightle adjust it eighter to the right or left to tuen the idle (For electronic controlled axcelleration) in some cases it can be adjusted via an ODB2 diagnostic tool (only in some vehicles that has electronic controlled axcelleration)
You can tell what type your vehicle is by looking for an axcelleration cable connected to the throttle body. If the throttle body has a cable it isnt electronically controlled and has an idling screw. If there is no cable but wires to the position sensor its electronic.

Based on the codes you gave the high idle is because of the EGR valve. (12,13 and 34)
21 is a temp sensor code, and I don't have a 44 listed. I hope this helps.
