Converting Ur OBD Setup

I drive a 91 with an obd0 and when my check engine light comes on I can't take it anywhere in town to see whats wrong with it. No one has the equipment to check it and I dont want to drive an hour or two to find out whats wrong. Can I convert it to an OBD1 or OBD2? If not anyway to check whats wrong myself?

check the codes yourself

5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor

20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean

ok pull back your carpet on the passenger side and youll see a metal plate with a hole in it and a little light. count the number of blinks, it will blink your code, pause then start over again, so say you got a code 3, it will blink 3 times pause then start 3 over again.

so check it then cross check it with that list above

Thanks guys
