Can anyone suggest a cheap but good ODBI code reader for a 90 Accura Legend
LS?

I see that Kragen has some dual ODBI / ODBII code readers listed online,
but they say they are compliant with DOMESTIC ODBI specifications. They
say they are only compliant with Honda / Accura cars being built after 96,
so I am guessing they aren't compliant with foreign ODBI cars!?!?!?

Maybe I am just confused about this. But if you can clue me in, that would
be greatly appreciated.

Checker Auto (part of the Krager chain) has a kit called "Import Vehicle
Code Reader" for 1983-1995 Toyota/Lexus, Nissan/Infinity and Honda Acura. It
cost me $35 and consists of a $30 book with a $3 Toyota jumper tool and a $2
Honda jumper / Nissan screwdriver. If yours has a 2.5 or 2.7 engine, you
don't need even the book. Instructions are to warm up the engine first (I
assume only if it is practical), turn on the ignition and look at the LEDs
on the ECU (it doesn't say where that is on the '90, but 87-89 are by the
passenger's toes under the carpet). Codes are flashed out with 2 second
pauses between codes. The LED will stop flashing when all codes have been
displayed. Codes are erased by unplugging the "Alternator sense" fuse for 10
seconds. The book lists 37 codes, so I don't want to post them all (lazy, ya
know) but if you post your codes I can identify them.

If your engine is not the 2.5 or 2.7, the book doesn't have a listing.

The 90 Legend (at least my L coupe) has the LED in the same place,
under the carpet in the passenger footwell. You don't need any
jumpers. You do need something to decode what X number of flashes
means. The 909 Legend uses the 2.7 liter 6.

As a public service and because I don't have anything better to do, here are
the Honda/Acura codes:

0 ECU or ECU signal (how does one of these display code 0?
1 O2 sensor / circuit
2 same as 1
3 MAP sensor / circuit
4 Crank angle sensor or engine speed sensor
5 same as 3
6 ECT sensor / circuit, automatic transaxle control unit
7 TPS (throttle position) sensor / circuit, automatic transaxle control
unit
8 same as 4
9 CMP sensor / circuit (whatever that is)
10 IAT sensor / circuit
11 Idle Mixture Adjuster sensor / circuit
12 No EGR action / faulty EGR valve
13 Baro sensor / circuit
14 Idle Air Control valve / circuit, ignition signal circuit to ECU
15 Ignition output signal to ECU missing
16 Open or shorted fuel injector circuit
17 VSS (vehicle speed sensor) sensor / circuit
18 Ignition Timing Adjustor open or shorted control circuit
19 A/T lockup control solenoid circuit open or shorted
20 Electrical load detector / circuit
21 Spool solenoid valve / open or shorted signal circuit (wonder what
*that* is)
22 Valve Timing Electronic Oil pressure switch / open or shorted signal
circuit
23 Knock sensor / circuit
30 AT/ECU communication signal A (AT control unit or ECU fault, maybe
harness)
31 AT/ECU communication signal B (AT control unit or ECU fault, maybe
harness)
35 Traction control / ECU / signal
36 same as 35
41 O2 sensor / heater (left side)
42 O2 sensor / heater (right side)
43 Fuel supply system (left side) (O2 sensor or circuit, or bad fuel
delivery)
44 Fuel supply system (right side) (O2 sensor or circuit, or bad fuel
delivery)
45 Fuel injector metering (left side)
46 Fuel injector metering (right side)
48 Heated O2 sensor / circuit
53 Right knock sensor / circuit
54 Crank angle sensor #2 or circuit
59 CMP sensor / circuit (whatever that is) #2

The other codes are not listed.

Hmm... the server seemed to reject the original post. Trying again...

Thanks Nat_mann;

will try to look for it there and see if I can figure it out.

Thanks Michael:

I also went online and saw there was an equus 3173 code Reader and that it
has some information about reading the codes in a manual which, as fortune
has it, you can dowload for free (legally!).

so I will try that first. Thanks again for pointing me in the right
direction.

Mark

I should have mentione that anyone interested in downloading this amnual
can do so by going to the following link:

Thanks again

That's the one I have! For $35 less (sob).

Your car does not require a "reader". Natman has the right info.
