is that even a code?? pr3 ecu w/ b16a

i got 2 long flashes

then pause for 2 seconds


then 2 long and 3 shorts close together,

code 2 = 2nd o2
but i cant figure out code 23

 

heeeeeeeeeeeeelp

 

If your first code is 2 long flashes then it's NOT a 2 it's a 20... that's for your ELD which is probably not wire up for some reason... Did you swap the fuse box??? The other code 23 is for your KS... Did you wire that up??? If so double check you're wiring, if it all checks out good then check the sensor itself... Peace

 

im pretty sure that first code was the o2 sensor becuase i reset the ecu and it went away, i went over the wiring and that seems fine,

i was reading about knock sensors and was reading that over heating might cause it to knock, for some reason my fan will not kick on automatically, it doesnt matter how long ive been running, and the car doesnt overheat at all, i know the guage works because about 2 weeks ago it was overheating when i had a bad hose.

soo when i reset the ecu, turn the car on, turn the ac button on and put it on no. 1 i can beat the **** out of it with no cel. i dont have an ac fan, or ac setup but the ac fan will work the cooling fan. so i think this might be a quick fix, i think im going to wire the fan up to the fuse box to come on automaticly.

and if i remember correctly the eld is a wire your suppose to remove when putting a b16 into a crx si.

 

any ideas?

why does my fan not come on when it is suppose to?

 

Sorry I took so long to respond but i haven't really been on H-T lately.... Anyways I have NEVER heard of high temperatures creating a knock nor do I even see that is being possible... A KS works with crystals just like a BBQ ignitor that generates voltage which looks similar to VAC on an osilliscope with vibration... Heat has nothing to do with it... As for your radiator fan not turning on have you checked your ECT switch... I assume that you have a 1st Gen B16A which has it's ECTSW mounted on the back of the block near the oil pressure sender... On all new motors ('92+) you'll see this same switch on the thermostat housing... It looks a little bit different but does the exact same thing... As temperature increase resistance decrease... It's just completes a circuit... I don't really understand what is going on with your A/C etc. but it all seems all too much like your wiring is messed up... How? I don't know... Let me know if you need anything else or if you figure anything else out... Good Luck
