Hi im new to forums so hope im in the correct place to ask.
ive saab 93 1.9 tid 150. Had a full service and after that my engine temp was not going about quarter so replaced theormostat a bit better now roumd town but soon as I hit motorway temp drops again ????any ideas why?
2... when remapping the car I got fault codes.p0268
P2147
showing on injector 3 high voltage??? Qny one have info on what these mean and a fix solution.
3.. only getting 31/33 mpg around town not going over 2/2.5prms seems very lows to me yet on a run on motorway I get 64.5mpg ...these mpg are brim to brim very confusing. Are the codes relating to poor town mpg??
Welcome! :)
P0268 is a wiring fault on injector 3. There is a known fault on the wiring on this injector. You can buy a kit of parts from Saab or Vauxhall to fix this. Engine is used in Saab, Vauxhall, Fiat etc. Parts are probably cheaper from Vauxhall.
I'm not sure about P2147. Saab manual states that it's a fault in either the Injector 1 or 4 wiring. But it also says that this fault should stop the engine.
It would seem that you need to check the wiring loom in the area around the thermostat. If it's fragile and brittle, it may well have broken.
Was the thermostat replaced with a genuine Saab one? There have been problems reported with cheap copies.
Hi ill double check the codes shortly and the theormostat was 55 at trade price as a friend our ours has a garage. So unsure if it was genuine.
P0268 cylinder 3 injector circuit hight
p2147 fuel injector A supply voltage
There what results came on the reader
If you can get to a Saab garage, the Tech2 reader can show some sub-divisions of those two codes.
P0268 splits into 3 parts:
P0268 01
P0268 0F
P0268 59
They are similar versions of the Injector 3 wiring fault. The attachment below is for P0268 01. The other two have exactly the same info in the manual. The detail comes out using the diagnosis program on the Tech2 computer.
Similarly for P2147. There are three sub-divisions
P2147 02
P2147 08
P2147 0F
Again the workshop manual uses the same description for all three, so the detail is in the diagnostics.
Great thanks I think ill have to take it to saab humberside its in my town. Had it read x2 at a local garage with no faults had a full gold service. A remap and thermostat. So may have to wait till just after xmas. Hopefully it will sort out my low town mpg....get it sorted and save up for different diesel had a few probs a and to be fair dont rate them that much .they look nice (93) but a bit rattly old feel inside
Well had car in humberside saab....could not see any faults clean wiring etc....no faults....get Home and starts cutting out fault codes again on my plug in comp...Would a auto electrician give me better results than saab?
It's probably something nasty lurking in the wiring loom, I've had more than a few where finding the fault took a couple of days and rectifying it took minutes. I'd certainly not expect a main dealer to do this for little money.
Hi everyone long time no see as car been running great till this week,driving along and car cuts out,if you dip clutch and try bump start it wont fire but if you switch off ignition and start on key as you are moving it will fire up straight away(when cuts out ignition lights come on)On the 1st cut out i had codes P0268 and P2150 and the second time(this morning whilst pulling out of a junction) P2150 and P2150P.I have done a bit of research and it looks like wiring or ecu problems.Any ideas Please. I have cleared all fault codes to remove warning light but i think now i will leave alone so they wiil store
As soon as a code resembling an ECU problem and also a wiring problem turns up, I would look at the ECU connector pins. They corrode or get pushed back into the connector. Two connectors, both in the ECU which is fitted behind the front right wheel arch liner, under the headlight.
Oh dear!thanks for reply i am up to my eyes today but have a day off tomoz ,is it right as you look at front or view from steering wheel?I know you have not got a crystal ball but is it an expensive job if ecu is damaged.Will a spray off wd40 solve corrosion prob if not damaged pins,is it worth plugging into tech2 or just wait and see if it gets worse.The car runs great no misfires but wether coincidence both times was in dark with headlights on ,no problems during the day.Many thanks
Just double checking that you have a 1.9 diesel?
The Engine Management Unit is accessible by undoing the small bolts in the edge of the wheel arch. This releases the edge from the end of the bumper. The liner should than be flexible enough to be bent away enough to look (Saab say take the whole liner out). You can then see the Management Unit. Undo the connectors and have a look. Spray with an aerosol contact cleaner.
It's where the purple spot is.
The connectors are at the bottom (Items labelled 3)

I would strongly suggest not trying to get to the ECU unless you have to, there is a good chance the connectors will break or be seized, if you must do this then you need to clean them up before you attempt to disconnect them and be very careful. I've had more than a few of these connectors fall apart on me.
At this point if you do not have a wiring diagram and the ability to check the loom properly you really need an auto-electrician or Saab specialist who has lots of electrical experience who will be able to investigate this for you. Pretty much every single 1.9 diesel that had a wiring fault had corroded wires in the loom (and always not easy to find) and not a problem with connectors or pins.
I have found an ex Saab fitter running from his home garage who says its a wiring loom prob and not to touch the ecu unless nescessary.After discussion i have decided to see if it happens again then get it straight into him. Thankyou everyone for your help.I think this prob will come back to haunt me and if it it does i will come back straight away with any info to help others .Its a 1.9 8v tid 53000mls 2006 and been a fab car that has hardly cost me a penny .
Well i spoke to soon as the flywheel failed on Friday made one hell of a noise and came out of nowhere as no noises beforehand.Car is on ramp with box out awaiting parts on Tuesday.Have seen flywheel and it has seized solid not allowing any movement so is of center causing the bad vibration and grinding noise,clutch is fine.53000 miles and clutch and release bearing is fine,how shit is that.It is having the lot changed
Bad luck!
The more I hear about these dual mass flywheels, the happier I am that I drive an automatic.

If I had to have a diesel (which I wouldn't unless I had to drive 18k+ a year) it would certainly be an automatic ;D although, I did see Cambridge Saab were doing a special offer which is DMF + clutch replacement + labour with new genuine parts for £600 including the vat. recently.
