Default d4 light flashing


I'm having trouble with my 94 Honda accord. I did the paperclip method on car and the d4 flashed these codes. 4, 7, 8, 14 and 1. please identify codes so I can get them fixed.

thank you.

Is the speedometer working - one of the codes points to the VSS, sometimes one fault can cause "others". Don't hold me to all of the below, it is a bit early and not much coffee yet

TCU Codes:

1-Lock-up solenoid 'A' circuit open or shorted.
2-Lock-up solenoid 'B' circuit open or shorted.
3-Throttle Position Sensor circuit open or shorted.
4-Vehicle Speed Sensor open or shorted - No signal from speedometer.
5-Shift Lever Position Switch circuit shorted.
6-Shift Lever Position Switch circuit open.
7-Shift Solenoid 'A' circuit open or shorted.
8-Shift Solenoid 'B' circuit open or shorted.
9-Counter shaft or transmission speed pulse generator open or shorted.
10-Coolant Temperature Sensor open or shorted.
11-Engine RPM (Ignition coil signal) open or shorted.
12-(No code 12 used)
13-Main shaft speed pulse generator open or shorted.
14- ?
15-Kick down switch circuit shorted.
