The noise is a bad sign and could mean the throttle body needs to be replaced, you do not need to do a relearn when the battery or the throttle body is replaced but there is a TPS set up procedure, here is how the job is done once the throttle body is replaced.
D. Connect the throttle position sensor connector.
E. Connect the hand-held tester or OBD II scan tool to the DLC3.
F. Turn the ignition switch ON.
NOTE: After turning the ignition switch ON, do not depress the accelerator pedal.
G. While reading the valve of the throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA, turn the throttle position sensor slowly to left and right and set the sensor at the center value of the standard value, and then tighten the screws.
Standard throttle valve opening percentage: 16.8 - 18.4 %
Torque: 2.0 N.M (20 kgf. Cm, 18 in. Lbf)
NOTE: After turning the ignition switch ON, do not depress the accelerator pedal.
H. Recheck throttle valve opening percentage.
If the throttle valve opening percentage is not as specified, repeat step (g).
I. Perform fully closed throttle valve by hand and check that the valve of the throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA stays with the standard value.
Standard throttle valve opening percentage: 10 - 14 %
If the throttle valve opening percentage is not as specified, repeat step (g) to (i).
J. Paint the 2 set screws.
K. Turn the ignition switch OFF.
L. Disconnect the hand-held tester or OBD II scan tool from the DLC3.
M. Disconnect the throttle position sensor connector.
7. INSTALL THROTTLE BODY ASSY
a. Install a new gasket and the throttle body.
Torque: 20 N.M (199 kgf. Cm, 14 ft. Lbf)
8. INSTALL FRONT SUSPENSION UPPER BRACE CENTER (W/ FRONT SUSPENSION BRACE UPPER CENTER)
Torque: 80 N.M (816 kgf. Cm, 59 ft. Lbf)
