Am i right thinking the injector codes are under the electrical connection. and are the double row. Because I've not been able to do pump or pilot learns. I've compared those to what's on read fuel injector correction factors and none of them match.

[knobby1]

If they don't match, someone may have changed injectors at one stage and not done the required correction factor change. It will run but will never pass the pilot or injector learns and never run at it's best.

It should pass the pump learns though, unless there's a silly amount of leak-off. Are they the original injectors or new/repaired..??

Yep,they are the correction factors....
Update those to what you have fitted,then redo pump and injector learns...

[Davehalldy]

Yes i put them codes in and tried the learns again sounded better straight away. But kept still on failing on cylinder 3. Can't do a leak off test until connectors turn up for my kit. But seems its looking like a injector.

Dtc p0268b. This code is given me a serious headache now. High voltage draw on cylinder 3. Cant do learns because of it. Fitted a reconditioned injector in 3 today entered the code in. Still the same checked the wires between injector and pcm all seems OK checked resistance on wires ok. Plugged another code reader in just says learns not done. No idea what now.

No idea what now.is there a way to check pcm. I don't know anything about them. If it was pcm i wouldn't have a clue how to identify the correct one for mine or how to program it ☹️. I have tried ringing a couple of local transit specialists but they have a back log. And come the end of the week i will have to give my daughter her car back leaving me with no transport fo work.

Just tested the power on the end of injector leads with ignition on 2.32v is that correct. Or would it not go up until cranking.

Managed to get the van booked into a auto electrician on Wednesday. Fingers crossed they can find the fault.

Injector codes are on a sticker on the injector not the plug injector need to be removed to see code.
Shouldn't really have voltage unless running. Possibly coil failure inside injector.
I've had canbus problems with transit due to corroded earths terminal on the vehicle under bonnet and passenger side. Vehicle earths not battery earths

Which code are you talking aboot..??

The "factory correction factors" are printed on the plastic electrical connector of each injector.

[Davehalldy]

Auto electrician just rang. He cant find the problem. Tried three different machines on it. Cog light still on won't do learns. Apparently still drives ok. Now what.

You still haven't told us if you received "NEW" correction factor with the reconditioned injector.

[Davehalldy]

Sorry yes it accepted the correction factors.

[knobby1]

Sorry yes it accepted the correction factors.

Not the one written on the reconditioned injector, the new one they should have given you for the reconditioned injector.??
