There is no recommended adjustment for the TPS but it does have some free travel so you can try adjusting it. Seat it as cloe as possible to the original position.
I believe you have done this step.
10) Code 63/122:
Attempt To Generate Code 53/123 or 23/121 Code 63/122 indicates TP signal is less than minimum self-test value. Refer to Fig. 15
Possible causes for this fault are as follows:
TPS not seated correctly
Open circuit in vehicle harness
Grounded circuit in vehicle harness
Turn ignition off and wait 10 seconds. Disconnect TPS from harness. Install a jumper wire between VREF and TP circuit at TPS vehicle harness connector. Perform KOEO SELF-TEST. If no codes are generated, immediately remove jumper wire and go to step 14). Check for Codes 53/123 or 23/121 (ignore all other codes at this time). If Codes 53/123 or 23/121 are not present, remove jumper wire, and go to next step. If either Code 53/123 or 23/121 is displayed, replace TPS.
Next to do would be the following.
94) Continuous Memory Code 63/122:
Monitor TP Circuit Under Simulated Road Shock Conditions Enter KOEO wiggle test. See CONTINUOUS MONITOR MODE (WIGGLE TEST) under QUICK TEST. Observe VOM or diagnostic tester for indication of fault while performing the following:
Slowly open throttle to WOT.
Slowly bring throttle to closed position.
Lightly tap TPS and wiggle connector.
This test checks for open or short in TPS, connectors and vehicle harness. If fault is indicated, disconnect TPS. Inspect connectors and terminals. If connectors and terminals are okay, replace TPS. Clear Continuous Memory Codes and repeat QUICK TEST.
This is the range chart which you can check if it is within range.
