Re: 90-93 accord and obd1 cel codes....
No they don't work. I got into an accident years ago and all the wiring near the left front panel got all screwed up and they haven't worked since, along with other electrical problems.
But I'm also having problems similar to this:

Re: 90-93 accord and obd1 cel codes....
another question about codes:
if you're getting more than one code, would they be in numerical order?
for example, if I'm getting a 7 and a 10, wouldn't there be 7 blinks first, then 1 long beep next, not the other way around?

Re: 90-93 accord and obd1 cel codes....
Yes, they will be in order. The long pause that comes at the end of it reading all the codes you have stored is about twice as long as the pause that comes in between codes.

Re: 90-93 accord and obd1 cel codes....
Hey, do you have an accord or are you just guessing? The blue plug is there. I have worked on CB7s for over 4 years now, and they all have blue plugs. Unless some one cut it off and left it off.

Says injectors but I got gas to them firing order right I smell the gas after a couple starts would it come up injectors if a single wire from the exhaust O2 sensor was cut by the fan

Re: 90-93 accord and obd1 cel codes....
Hello fellow Honda enthusiasts! I've been reading through this post, and have been busy trying to get trouble codes myself! It happens that you do NOT need to jump the SCS wire to obtain codes!
1.) If you pull back the carpet on the passenger side floor you will see this metal panel (Please excuse the blurry photo)

2.) If you then look in the upper center of the panel, you will see a little LED light like this (Once again, sorry for the blur) its easy to spot!

3.) If you turn your car to the on position (DO NOT crank it all the way over, only until your lights and accessories turn on) the LED will flash your OBD-1 trouble codes. No jumping or digging for wires needed!

Re: 90-93 accord and obd1 cel codes....
Hello I know this is for an accord. But I need help ASAP! Please I have a Honda civic 93, my CEL recently just came on I have been looking everywhere for an obd1 but no one has it now an days... So I tried that paper clip DIY thing and it pulled 4 long blinks. Does anyone know what that means? Please I need serious help I would appreciate it a lot. I would have to keep wasting money on replacing uneccessery parts. I'm the time of guy who likes to keep these old cars running great. Thank you

Re: 90-93 accord and obd1 cel codes....
After 19,000 threads about how to do this, I decided there was a need for one of these. I thought there was one.. but I dunno. Motion to sticky ... mods if you wanna change the thread title to "how to .... " that would be kew.. i forgot to add that.
1. If your check engine light is on, start by going to your passenger side kickpanel.
There should be a blue connector w/2 wires to it like the one pictured below.
Put a paper clip, wire, connector in it to connect the two prongs.
2. Put the key in the ignition, and turn the key 2 clicks to the acc on, where all the lights light up on the dash.
3. You will now watch how many times the CEL light blinks.
a long blink = 10
a short blink = 1
It will repeat after all the codes are done.
4. Compare to this list to see what the problem is:
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's
41 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
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Fuel Tank Pressure Sensor low input
92 Evaporative Emission Control System insufficient purge flow
TCU Codes:
CODE LIST:
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.

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-Linear (line pressure control) solenoid open or shorted.
15-Kick down switch circuit shorted.
Resetting ECU
1. Disconnect Negative battery terminal (never only take off the positive, cuz it can kill the battery when it grounds all the power out, if left for a while)
2. Look in the Underhood fuse box, find the "Hazard" Fuse. Pull it out.
3. Let the car sit for 10-15 minutes
4. Reattach neg battery terminal and put fuse back in
5. Restart car w/nothing on (radio, lights, a/c) and just let it run for a few minutes.
6. Turn off, and then it should be good to go.

Re: 90-93 accord and obd1 cel codes....
That plug for the Accord is present on both OBDII vehicles (96/97) and OBDI vehicles. If you have an OBDII vehicle you should use the OBDII scanner - there are cheap ones on Amazon that are bluetooth even. I think Autozone/Advance Auto have stopped scanning for free though it's worth asking.

Re: 90-93 accord and obd1 cel codes....
Hello hello. New to this forum, but glad to be back in a 4th gen accord, this time a wagon. She is throwing multiple TCU codes - 1, 2, 3, 7, 8, and 14. Doesn’t want to shift into 1st or 4th. Any ideas why so many codes could be triggered all at once, all of a Sudden? Recently replaced battery and distributor. Thanks.

Re: 90-93 accord and obd1 cel codes....
Hello I have a 1990 Honda Accord LX.the problem on my car is the S it flashes all the time.the car starts fine but when I put it in D4 it drives but it don't shift 2,3,4.automatically.i change the TCU for an oreillys and plug it and same problem.what is your advice.

Re: 90-93 accord and obd1 cel codes....
Hi is my 95 odyssey the same as the accord?
any way the OBD1 has code #1  I replaced the electric valve ficv and blocked off the iacv , also some idiot cut the wires to the oxygen sensor #1 the motor runs strong but still surges and jerks upon acceleration , I have checked almost everything for a vacuum leak , I'm really at a loss as what it is HELP PLEASE.

Resetting ECU
1. Disconnect Negative battery terminal (never only take off the positive, cuz it can kill the battery when it grounds all the power out, if left for a while)
2. Look in the Underhood fuse box, find the "Hazard" Fuse. Pull it out.
3. Let the car sit for 10-15 minutes
4. Reattach neg battery terminal and put fuse back in
5. Restart car w/nothing on (radio, lights, a/c) and just let it run for a few minutes.
6. Turn off, and then it should be good to go.
