I used the light on my ecu to determine my engine code. The flash sequence I got was one quick flash with a short pause plus 16 other quick flashes....... Like what the hell is that all about?

 

You can throw more than one code. The pause is to seperate engine codes. When you turn your car on, it will make one quick flash, then it will start flashing the code. Watch it for about 30 seconds. It should flash 16 times, pause, then 16 more and it will continue as long as the problem is there. Good Luck - Darrell

 

ya thats what it does, it's 16 flashes, they're all the same length too. and no pause in between. Does anyone know what that is?

 

if it was 1 long dash and 16 short then you threw 2 codes, code 10 and 16

 

well the first one is apparently just to let you know that your ecu is online. What kept repeating was the quick 16 flashes.

 

16 is your fuel injection system, many different things can be wrong, whats the problem your having with your car?

Just to add our abd-0 ecus dont have the 1 flash = 10 thing, all codes are done in short flashes, at least thats how all of mine have been with pm6 ps9 and pg7 ecus

 

So for obd0 16 quick flashes would just signify a code 16?... I don't know what problem my car has... all know is that I have a this code that my ecu puts out.

 

So your car doesnt sputter, hesitate or anything? runs fine? May just be a fluke code, disconnect your battery for 30 sec, connect back, start it up and let it idle till the fans come on and shut it off. Dont touch the gas. The code may go away, if not then you do have an actual problem.

 

Ok, but how about the OBD0 reading, is it the amount of flashes = the code?

 

# of flashes = code. 16 is fuel injection code as stated. do you have a manual for the car?

 

code 16 can mean a lot of things

Also if you guys didnt know OBD0 ecu's dont use the long flash as 10, were old school

 

Yes # of flashes = the code. the long flash is only OBD1 cars and the long and short flashes on them is the CEL. OBD0 = no long flash.

 

Code 1 is for Oxygen content. Code 16 is for Fuel Injector. I have the book right here on my desk so I am not blowing smoke in your bum-bum. My guess is that your O2 sensor is getting old and one of your injectors is giving the ecu a load (clogged or bad.) I hope that helps. Do you have Dual-Point or Multi-Point injection? Does your car seem to have a miss? Does the high end seem like it works okay?

 

I have multi point, and it's more like as soon as I shift to 3 gear that there's is one point where the engine misfires or something because I barely accelerate even if I have my pedal right down to the floor, but then after about 2 seconds it goes back to normal.

 

Is it your daily driver? If it were me, I would send those injectors off to be cleaned and buy a new O2 sensor. RC Engineering does a great job of cleaning injectors. They will send a printout of before and after results. we sent some 550s from an RX7 in and they were only pumping 464. When they finished cleaning them, 3 of them did 550 and one was 549. I like those guys' work. That would be hard if it is your daily driver because it takes at least a week. Well, I hope this helps. Good luck.
