Alright guys, I started a thread about this earlier...heres an over-view:

1.)installed o2 sensor for a obd0 acura integra
2.)installation went smooth, wired correctly
3.)reset ECU for approx 5 mins, but still threw the o2 sensor code
4.)reset ECU for 10 mins, still threw code
5.)left it out all night, still threw code ROFLOCOPTER
6.)Someone suggested it may be a leaky injector, well..I got a NOID LITE and a stethescope, checked all the harnesses and injectors themselves. The NOID LITE blinked like it was supposed to, and I heard a strong ticking from the injectors. A-OK.


So ya...Im still throwing the code. Any suggestions?

 

bump?

 

cmon guys, no one knows?

Bump for more info, I still have to extend mine from the new header install, but for some reason my ECU only throws the code randomly. I've been getting it once a week since the sensor's been off. Is that the only code it's throwing?

 

What code were you throwing and are you throwing now? If it is O2 related maybe you get a cracked manifold or like other said, stuck injector?

Take a look at your plugs and see how each cylinder look? If one is abnormally dark then you have injector problem. If all look pretty white/lean then you probably have cracked manifold. Let us know how it goes.

 

ehh, wierd. Well, after I reset the ECU, it kept giving me Code 15. Which has something to do with ignition spark pulse or some BS. Im about to have to choke a bitch(caR).

And just today, my car died for no apparent reason, and it is rather hard to start back up. But sometimes it doesnt die at all when I drive it...it just comes unexpected. Mo wird noises or anything.

 

Alright guys, update #4, my car is dead..like dead. It turns over, but it rarely starts. I dont know wtf is going on.

 

code 15 is ignition out put signal. check your distributor wiring, the two wire plug (blue and black/yellow). make sure you have battery voltage (or 10V) at the black/yellow wire and ground at the blue.

if all is well, check for spark (unplug your resistor box, take out a plug, have someone turn the car over while you touch the plug to the valve cover/block/manifold).

if you have spark, fuel and air, check your computer wiring. unplug the ecu itself, check for frayed wires or pins in the harness that might have pushed out, plug it all back in and make sure it's snug.

also check your grounds.

 

btw, when you check for voltage, is that with the car on?


and also, to make sure I check all the grounds, how many are there? I know there is one next to the clutch cable, one on the alternator, and the two on the valve cover...what else?

alright, i did all of those checks, they came out fine.

Now...I tried banging on my Main Relay and then it started.. would a faulty Main relay trigger the CEL 15?
