I recently just bought a 94 accord and it throws a check engine light every now and then. The original owner said that it was the o2 sensor because he ran a test and got a 44 as the code. I was just wondering how i run the test that shows the code?? Thanks for all your help

 

1.) Locate the blue 2 pin jumper plug. IIRC It is attached to a metal support under the glove box above the passenger's kick pannel.



Once you have found it you can pull it out of the retainer that it is in.



2.) WITH THE CAR OFF, insert either a 2pin connector clip, paper clip, or loop a thin enough piece of wire into both holes on the connector. This will short or close the loop telling the ECU to send the code to the MIL (CEL) on your dash.Basically you want to connect the two contacts together.

3.) Back in the driver's seat, turn the key to the 'ON' position. The CEL light will come on at startup, like normal, but it will then begin to flash.
**By counting the number of flashes, you can decipher the CEL #.
SHORT flashes are single digits (1/2 second)
LONG flashes are 10's (1 second)

You may have multiple codes, if there are multiple codes there will be a slight pause between the sets of code flashes.

Ex
short...short...short Pause long...long...short...short...short

In this example you would have a code 3 & 23.

 

GhostAccord... In your reply to FTW_Accord94...

You said for 23 the flash sequence would be: short, short, long, long, long

I think I get what you are really meaning, hopefully...

Wouldn't 23 be flashed thusly??? long, long, short, short, short

This is a cool thing to know... I just want to be sure I understand you.

 

yeah sorry about that, my example was wrong.......fixed now!


Thanks for pointing that out.

 

Alright thanks, Its hard to believe it is as simple as that haha
