this is my bros car so i dont know to much about it. he brough it to me and said it feels like its funnin on 3 cylinders so i take it out and yes it is runnnin like complete crap. So i pull the carpet up to check the code and it blinks 16 times pauses then blinks 16 times again. I dont kno much about the codes so could some one please help me out right quick
THANKS

 

thats not right make sure ur reading that code correctly!

 

My CRX is doing the same thing. 16 evenly spaced blinks. It sometimes runs like crap but only before it's warmed up.

Bump for help.

then im confused!

 

i just went out and checked it again it is deffinately 16 evenly spaced blinks i just read a list that suggested maby the fuel injector

 

ok i reset the ecu it doesnt blink anymore but it still runs like crap but no check engine light. injectors are good

im lost

explain

 

try the main relay thats what was wrong with mine when it threw a code 16

 

if you had a code 16 wouldnt it be 1 long blink and then 6 short blinks... i dont get it can u determine if any of those "16" blinks are short or long?

thats what ive always known

 

thats what i thought too untill the other day i check my ecu and it did 16 short flashes thats when i replaced my main relay

 

I had 16 short flashes. Checked injectors and replaced fuel filter and it went away.

DOHC ECU is 1 long blink meaning 10 and 6 short in this case meaning 16. SOHC ECU is just short blinks ( no long blink) that you just have to count carefully couple of times. I had a SOHC ( PM6) now DOHC (PR3). I have had experience with both ECUs. Someone correct me if Iam wrong though

i dont think thats right. im pretty sure thats not right

 

&lt;- PM5 - 16 short blinks.

I think people arguing about how the ECU displays the code is besides the point, and is a rather stupid argument.

original poster, I searched for "CEL codes" on h/t and managed to find scans of the Helms manual with a flow chart to help you troubleshoot the problem. They first have you check wiring, and then the injectors.

This could be a VERY easy problem to fix. It was for me.

it's right, my VSS code was 17 flashes. But I wouldnt say DOHC, because d16a1 are short blinks too i believe. I would say pr3/pw0 are long/short blinks and maybe even pr4 (not sure on pr4). but definately pm6 only does short flashes (first hand experience).

 

now for the actual question here.. 16 blinks = injector code.

1. check physical wiring how does it look

2. check resistor box wiring

3. check continuity from each injector to it's ecu wire location. then check for loose grounds (specficially the thermostat ground).

4. with engine running take a long screw driver and put the metal tip to the body of the injector and the handle do your ear (actually touch your ear). You should be able to hear the open/closing of the injectors resonating through the handle. what you're looking for here is similar sounds from each. if you find one has a very different sound then get a new one. This car is DPFI right? I'm not sure if both injectors are the same 240cc but you can find that out later, point is if one sounds funky replace both.

5. if they both sound the same (click click click click click) then try removing them and inspecting for debris in the little filters on the top of each one, and possibly replace the fuel filter. follow the manual for removing injectors so you dont get fuel everywhere.

 

well i reset the ECU, the codes doesnt flash anymore but it still runs like ***??

 

anyone pls help me out i have to run so i dont have time to search, and this thing needs to be running tomorrow.
sorry guys for being a pain in the *** but i need some quick fire honda-tech help

 

Code 16 from Helms :

Please check the FAQ next time. After you do all of these things (I'd also check the fuel filter) then let us know.

FYI, on DPFI the top and bottom injectors are different. They are NOT interchangable. Keep this in mind if you need to replace one.
