How or where is the plug to put in the code reader? Car runs fine

it's obd1.

there should be two sets of connectors under the steering column that are unplugged, one green, one black

plug in the black with the car turned off then turn the key so the power is on without starting the car.

the check engine light will flash at you

long flashes are first digit of the code short flashes are second digit

then look up the code you've just discovered

this link goes through the process really well.

Thanks

Can not seem to find black wire. What color does black wire plug into

Green and Black connectors, not wire colors.

 

They will be up under the dash, Slightly left of the column.  Possibly taped with masking tape to the wiring loom that goes into the ECU (computer box under dash)

 

Green connector wires will be orange wire at one side and Black/Red(ground) at the matching one.

 

Black connectors wires will be Red/Black and the match will again be Black/Red(ground)

 

If you can find the Orange wire in the green connector, and the Red/Black wire in the black connector.....you can simply ground them anywhere if you can't find their matches

Ok after reading code is it possible to clear code

Long long short short

Ok knock sensor. Code 22.could this be a old ghost code in memory??

Changed it o ut with good one.the old one was really cracked never changed

Nah, probably is for real.

 

Easy to replace.  takes 10 mins.  Just need a 12mm socket on a long extension and a good flashlight.

 

 

Once you fix it....to clear codes connect both sets of connectors, and start engine, run it 40 secs or more and drive it a few MPH forward/back.....when the light flashes codes are clear.  If it keeps giving you a code there is still a problem once all are fixed it will clear codes.

Got it thanks
