I have a 94 ls integra with b18b obd1 and was wondering how I can check to see what code I am throwing without using a computer or scan tool or taking it to someone? or if I can use a computer what hook ups or program I need to download? I will be doing research on this issue but I figured I would go ahead and post it, thanks HT.

 

by the passenger side glovebox, behind it, theres a connector, stick a paperclip in it, count the blinks on the CEL

Short blink = +1
Long blink = +10

You will get a code

9 short blinks = code 9
1 long blink followed by 4 short blinks = code 14

Thanks I found a video about the paper clip right after I posted this I just didnt know where the hook up was so thanks.

 

Well my codes were 8 short then they were 4 long then 1 short 41. Then 4 long and 3 short 43.

 

I know it's the 41 ho25 heater sensor and the 43 is the fuel supply system which I'm not to sure what that is and where it's located?

 

May be the same problem, the fuel supply system most likely refers to the PGM-FI Main Relay, [main relay] it is located just above the hood release.

Do you hear the fuel pump priming the fuel system when you turn the ign. switch on to run, [not start]?

When you turn the ign. switch on, [to run, not start] you should hear the fuel pump running for a few sec., this should happen each time you turn the ign. switch on. 94

check halfway down the page for 41 and 43

 

yeah it primes fine, and when I take the gas cap off it releases air so I know my fuel pump is fine, and it does have a new fuel filter.

 

I can't see where that is exactly located? the ho25 sensor, and does that just mean I would have to replace the sensor and fix the problem of course that is the problem lol.

 

which im guessing that the sensor is located on the exhaust just looked it up but is there only two ho25 sensors? would I have to replace both of them? or just the main one?
