hi i have a 1991 civic wagon with the d15 motor, and starting today the check engine light has come on

i looked at the ecu code under the front foot panel on passenger side

and the lights are blinking

16 quick blinks

pause

17 quick blinks

pase

16 quick blinks...and so on

can someone help me with what this might be?

 

nobody knows?

Code 1 _____ Oxygen content
Code 2 _____ Does not appear to exist
Code 3 _____ MAP sensor
Code 4 _____ Crank angle sensor
Code 5 _____ MAP sensor again
Code 6 _____ Coolant temperature
Code 7 _____ Throttle angle
Code 8 _____ Top dead center sensor
Code 9 _____ No. 1 cylinder position (only on 1.6L)
Code 10 ____ Intake air temperature
Code 11 ____ Does not appear to exist
Code 12 ____ Exhaust gas recirculation system
Code 13 ____ Atmosphric Pressure
Code 14 ____ Electronic air control (EACV)
Code 15 ____ Ignition output signal
Code 16 ____ Fuel injector
Code 17 ____ Vehicle speed sensor
Code 18 ____ Does not appear to exist
Code 19 ____ Lock up control solenoid (auto trans only)
Code 20 ____ Electric load

 

that is weird car runs perfect and speedometer works fine..

:sigh:

 

Pop the hood, look at the fuse box, there will be a fuse that says hazard, pull that fuse for my 10 seconds and then put it back in and start the car, see if it still throws codes.

 

thanks i will attempt that

 

i completely agree, pull the hazard fuse or just disconnect ur battery for about 30seconds, then put it all back together, run ur car, see if it lights up, if it does check ur ecu, see what code it is and go from there or post the results and we'll give u some insight. fuel injector may have gotten clogged and then started spraying again? could be a lot of things

 

i just disconnected the battery and the ecu fuse....will go driving today

 

with ur lack of another post hopefully u fixed ur own problem.

 

Don't disconnect the battery to clear out the ECU codes, because then you have to reset your clock and radio settings, if you just pull the hazard fuse that stuff won't be erased with it.
