well its 90-93.. 94 is completely differant. On the passenger side of your car, under the dash beneath the glove box, you will find a green cover above the kickpanel that houses a blue connector that has two wires.All that you need to do is turn the ignition off, and using the piece of wire or paperclip, jump the blue connector so that you connect the two wires together. Basically stick one end of the paperclip or peice of wire into one prong on the connector and stick the other end of the paperclip or wire into the other prong.Once you have done this, turn the key to the IGN position and watch your CEL light. It will illuminate in a series of flashes.You will notice that there will be LONG flashes and SHORT flashes. All of the ECU trouble codes are two-digits. LONG flashes determine the TENS digit by the number of times it flashes, and SHORT flashes determine the ONES digit by the number of times it flashes.ie. LONG-LONG-LONG-SHORT-SHORT-SHORT-SHORT-PAUSEis the trouble code: 34the codes are..1 O2A - Oxygen sensor #1 2 O2B - Oxygen sensor #2 3 MAP - manifold absolute pressure sensor 4 CKP - crank position sensor 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 14 IAC (EACV) - idle air control valve 15 Ignition output signal 16 Fuel injectors 17 VSS - speed sensor 19 Automatic transmission lockup control valve 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 36 traction control found on JDM ecu's41 Primary oxygen sensor heater 43 Fuel supply system 45 Fuel system too rich or lean 48 LAF - lean air fuel sensor 54 CKF - crank fluctuation sensor 58 TDC sensor #2 61 Primary oxygen sensor 63 Secondary oxygen sensor 65 Secondary oxygen sensor heater 67 Catalyst low efficiency.
