okay i have a 93 cx hatch with a d15b7 in it manual transmission as well as matching d15b7 ecu..

i have a cel code or atleast it says i do.. i jumped the connector like u are supose to but when trying to count the flashes all it does is flash on and off in 4 second intervals and never stops or has a longer pause.. iv sit watching this thing for 10 minutes now and it never restarted or paused longer then before...i can count 1 1000 ,2 1000, 3 1000, 4 1000 between intervals..

everytime i look up the code it dosent exist and i have no idea what it is iv checked and cleaned and replaced everything that could be at fault

 

no one knows?

 

That is probably a code. I know a long blink (1 second) is intake air temp sensor code. And a 1/2 second blink is 02 sensor

 

yeah but mine has no short blinks and all blinks are more then 1 second min are like 4 seconds.

 

take it to advanced auto or auto zone and have them hook up the scanner they can get you the code and its free

 

u can scan a obd1? i thought it was only obd2 that u used scanners on hell ill take it tomorrow then.. i donsent seem to hurt performace just annoying that its on.

oh and also mine is the cx model like i said and it as that upshift green arrow light that comes on well it used to come on but now it dosent and i think its related to the problem if anyone knows what would cause that not to work

 

the shift light goes off when there is a CEL, i believe this is due to the light being related to the o2 sensor. when you get the light off it should work again

 

ekhonda87 is right the 1 second flash would be cel-10~ IAT, n the 1/2 second is cel-1~ o2 sensor, the long pause in between is the cycle, if no more codes are present it cycles the same code. The AutoZone scanners are obd2 and as far as i know they don't do it any more. u are doing it right wit the jumper. question... when u re-set the ecu how long does it take for the cel to come back on?

 

yes i understand how the codes work but every flash is longer then 1 second and there are no fast flashes .. i even unpluged other stuff to see if it would flash right and it does. and after i reset the ecu the code comes back almost immediatly.

i swear if i had a cam i wuld video tape it. i think it might be the white plug on the back of the intake manifold.. if i unplug it the code dosent change or flash a different one. it has 2 wires going to it and 1 of em is green.

but the code never recycles each and every flash for as long as u want to watch is the same

 

i also hooked up a a/f guage out of curiosity and its pinging the guage at max rich and only barley moves to the leaner side when i give it lots of gas

 

okay and today now it is extremely hard to get it to rev over 3k.. it will but it takes a century.. and now my oil light is on but the sensor is hooked up and the oil is full..

could i be dealing with a faulty ecu? if it was wouldnt the cel just stay on instead of flash?

 

okay i took a video of it this isint the full thing cause my cell only takes 15sec videos.. but the spacing is the same for all the flashes no matter how long u watch it and it never ends<object width="425" height="350"> <param name="movie" value="http://www.youtube.com/v/NGUbeZw00DQ"> </param> <embed src="http://www.youtube.com/v/NGUbeZw00DQ" type="application/x-shockwave-flash" width="425" height="350"> </embed> </object>

 

sry here it is http://www.youtube.com/watch?v=NGUbeZw00DQ

 

i would swap ecu's and see how it does. then if you still have issues maybe you can narrow it down easier.

Most auto stores can only read OBDII for free. OBDI is a little different and they don't usually have the connectors for it.

Yes, we do.

The video looked like one long flash to me. So, 10.

i think NOFX is correct, after watching the vid, i would definitely call that a 10. Also, the white plug on the back of the in-man wit 2 phillips screws in it that u referred to is the IAT. BTW AutoZones around here don't pull codes any more, they won't even let u do it yourself. I guess its a local thing.
