sorry not a ford question but im sure someone might be able to help
does any one know how to do this its my daily driver and the diognostic light comes on now and it seems to have a miss fire, pug dealer want £70.
I have been told to do this, does this sound right

"Hi

Get a nice long length of thin wire, Strip some insulation of both ends.

A bit of solder to tin the wire if you can.

Insert one end of the wire in pin number 2 of your green diagnostic socket ( The same pin the fault reader plugs in )

Find a earth point on the car, Something metal & exposed, easy to get to, Or get a helper.

Hold the other end of the wire to this earth point & switch the ignition on but dont start the engine.

Wait 3 - 5 seconds & remove the wire from earth.

Diagnostic light should now go out & flash once then a pause then flash twice code 12 Start of test.

Hold the wire against earth for a couple of seconds & then remove.

The next code should then be flashed out.

Keep repeating this untill you get code 11 End of test Flash once then pause then flash again

Simple to do & free. "


what do you think?

Jim Galbally

sounds right to me im just ckecking in autodata for you now...

Jim Galbally

what year+model is the car?

1.1? 1.4? etc. etc.

jas

cool its a 96 n reg 1.6 XSi, i got a gunson fault reader but it dont work and i got this from another site

Jim Galbally

theyre lsted as 1995-1996 and 1996 only

any ideas which yours is? lol as theyre both very different

one is a 2pin connector, the other's a 30pin connector...

jas

its a feb 96 its got the 2 pin type connector, i know where that is sort of behind the drives head light under the ecu

Jim Galbally

is it bosch mono-jetronic injection?

the codes are different depending on which ECU type you have...

anyway here's the test procedure:

jas

umm its doing some radom stuff the fuel pump is going crazy.
did as above but i never got a code 12 1st i got 81 82 17 84, then it just seemed to go round in circles again and no 11 to say end of test.
I will give it another go
it magneti marelli managemen i have a copy of what the codes mean but i just dont seem to be getting anything which makes any sense

Jim Galbally

erm, the codes only go up as high as 79

and there's no code 17 either

jas

yippie done it code 14, collent temp sensor, time to go buy a new one thanks for all your help jim.
I was doing it wrong need to turn igintion on and them join the wires, if you join wires then turn on ignition it test the fuel pump and injestors

Jim Galbally

test the connection to the sensor 1st, it could be a wiring fault and the fault code is telling you that its not plugged in...

jas

good plan, all i have to do now is find it, to be honest i think its dead as i had the car about 3 weeks and this fault started about a week after i had it, would this cause a slight missfire and what i feel is highish fuel consuption

Jim Galbally

yes

jas

excelent i will check the conection any how, but would think i will need a new one

Top work Jim

jas

opps ive just done the test again 3 times and now im not getting fault cde 14 but 56=coded anti theft and code 52=lambda system control so is it infact my lambda sensor being fu*ck despite that being a code 51

Jim Galbally

check each sensor...

CTS is easy to do, just need a multimeter and a kettle...

dunno about lambda tho sure sum1 will know the lambda sensor outputs
