Ford Fault Code Reader
As Locost Builders seems to be the location of all knowledge I'm hoping someone knows the answer to this one.
We have a poorly 1997 (R reg) Ford Fiesta 1.4 Zetec in the household what type of code reader would I need as I'm getting conflicting answers.
Some say OBD2 works from 1997, some say only from 2001.
Would this also be the same for our 1998 (S reg) 1.25 Zetec Fiesta?
Thanks

Not sure enough to be any help on the OBD version I am afraid but the collective may be able to help diagnose the fault.
What are the symptoms/engine type etc?

Most ford's 97> have obd2 diagnostic functions.
I use a 97 mondeo ecu in my 7 and the obd2 is a great tool.
have you got an android phone ? Torque and a dongle does the job our do a search for a recommendation by british trident he recommends a good basic
one.

Originally started as stalling at around 1500 rpm on the over run. Fitted different coil pack and it ran OK for about 30 miles. When started for the
return journey it was totally lacking power and drivability. Got worse and worse until eventually it struggled to start and wouldn't idle.
Fitted new coil pack and now it will start and idle but lacks power and is not really drivable.
There is a good and reqular spark to each cylinder and the plugs look ok.
My list of possible causes is quite long so thought a £30 code reader could save a lot of time.
Possible causes.
Coil pack (despite being a new motorcraft one)
ECU fault
Timing out (cam belt trensioner fail / cam belt jumped a tooth)
Sensor failed (Cam position, crank position, temperature, throttle position, MAF....)
Fuel problem (injector(s), pressure, pump ...)

That seems to be the confusion USA started using OBD 2 in 1996 and it was adopted in Europe by 2001. For European cars, when a manufacturer switched
varied.
Best guess is that it is OBD2 or EOBD (is there a difference) I've also seen something that suggests OBD2 is different from OBDII.

A 97 Ford may or may not be OBD II even if has an OBD II sixteen pin socket not all cheap dongles will work on some older Ford models.
OBD II is to almost all intents and purposes the the same as EOBD and JOBD.
OBD 2 is simply a misspelling of OBD II.
For a USB or Bluetooth dongle look for one on ebay that specifically features being suitable Fords. (ie do a search on Ford OBD Bluetooth or
Ford OBD USB).
If buying a hand held scanner then even a cheap Autel or Memoscan would a safer bet than some unbranded item.
Although good basic hand held scanner such as the Memoscan U480 or Autel MS309 that will cover all protocols including the latest CAN Bus
are available very cheaply with a view to the longer term it may be worth shelling out a few extra bucks for one that covers live data and
freeze frame such the Autel MS509.

I have a Gendan ELM320 PWM protocol USB unit that worked with '96,'97 and '99 Mondeo's, I don't need it any more, you
can have it for a small donation to my IVA fund. You will need to find software on the interweb, that shouldn't be a problem.

copied from an earlier post from me when searching for a 98 1.4 fiesta zetec.....
I did a bit of reading and found which protocol my fiesta engine/ecu used: Ford J1850-PWM.
Then searched eBay and found a blue tooth OBD dongle that explicitly supports it. Was still a bit of a gamble but only £18.
It works fine.

Being able to read codes is one thing, from what you describe I would be inclined to check the fuel rail pressure, if its low expect codes for weak
mixture, you also get these if you run out of fuel.
Daughter had a 97 zetec fiesta, it was OBD2 btw

Ford Fault Code Reader - solved
Both Fiestas are definately OBD2. Thanks to 40inches for the code reader. The reader showed up a problem with the spark advance and lambda sensor.
Turned out to be one of the spark plugs that had a crack in the metal body (never seen that before) so that cylinder was losing compression/ sucking
in air which was confusing the sensors.
