i've pulled codes before on previously owned hondas, so im not a complete dumbass, but i recently purchased a 1989 crx dx. It has the stock d15b2 in it. but after about 6-7 minutes of driving, the check engine light comes on. Then i went to find the service connector to stick a jumper wire in it, and when i did, i turned the key to the last position, but no cel blinks. So my question is, is there a special way your supposed to pull the code on crx's or are all hondas the same?

 

The "CEL blinks" you are looking for is a red LED on the actual ecu. If you pull up the passenger side footwell carpet you'll see a gold plate with a hole in it. The blinking LED should be visible through the hole. And there is no jumper plug required to read it.

 

so when i turn the key to the III position, the ecu red light will blink to tell what code it is?

 

will the red light do the long and short flashes to distinguish the code?

on a DX with DX ECU there are no long flashes - all just short

Yep, just like the light in the dash otherwise would.

 

after you have gotten the blinks how do you fing out what code it is?

 

do the search option on here with whatever code number is usually what i do, but i have to figure mine out first.

 

FAQ much?

thanks guyz! i fugured out that it was a code 1 and 16 for a stock obd0 crx dx with a d15b2. it shows to be a faulty "primary" o2 sensor and a faulty fuel injection system. these motors run on only two fuel injectors, so it shouldn't be hard to fix. I want to keep this dpfi system for the meantime due to expensive gas prices. where should i start about fixing my problem?
