p0167- anybody shed any light?

[Grenadekid]

I know where you are comin from, its different when the car is your own, you will try a lot of things at the start and when you get pissed off because nothing works you wil give up and hand it to somebody else in hope that it will be sorted no matter what the price. At a certain stage, peace of mind comes before money and then to finish you off right some cowboy robs you for parts you never needed

on another note you offer me some hope that it might not be pump or injector related

[Altransit]

I'm running it at the moment with the electrical connectors removed, on the EGR valve and the EGR solenoid, and it seems to start better and smoke less, but is still powering down (losing acceleration) after a few minutes, so thats not the cause

I'll keep you posted as I try things

[Grenadekid]

I will post again on mon Altransit if i find anything on this transit of ours. Your symptoms might be slightly different from mine so could end up same fault code but totally unrelated problem

[Grenadekid]

Hi Altransit found a split vaccum pipe going through the bulkhead along with the heater pipes (can only guess it connects to the heater inside somewhere as the vans got aircon, back sore at the minute so i wasnt gonna crawl in to see).
My heater control valve is also missing but the vaccum tube to it is blanked, anyways when i fixed that vaccum pipe it cleared that p0167 code and i took van for a 10 mile run and it never reappeared also van is a lot more responsive now but still another couple of issues before i get full power. So maybe the mystery of p0167 is solved, i will know for sure next week as the van is away on a 300 mile round trip. In the mean time check out all your vaccum pipes and anything they plug into as the code seems to lie in the vaccum system especially if you have air con
Just to add our van had the same feeling of no turbo but a little more responsive now even though there doesnt seem to be much turbo boost but thats down to some other issuses i will try to get sorted next week

[Altransit]

Thanks for that, much appreciated

I haven't got aircon, but my next job was investigating the MAF sensor, and I was going to check that it had the correct vacuum to operate. The sensor itself has been replaced previously, but won't generate the correct voltages without the correct vacuum

All very interesting

Hopefully it will help you get to the root of your problem m8
I remember my connect had a vaccum pipe nipped on top of the gearbox but i dont know if it was wear and tear but it didnt seem to make any difference to the power. I saw it the time i was replacing my reversing light switch as it was right beside it, It was awkward to get at so i didnt bother fixing it but my van is quite smokey. You have started me thinking now if i should go out tomorrow and fix it just to see

[Altransit]

I'll report back

[Grenadekid]

just added another bit to my post above that might be of some interest Altransit

[Altransit]

Yes interesting, I wonder why there's a vacuum pipe down there
If your Connect is a TDDi then its the same engine as mine

[Grenadekid]

Mine is a tdci but the same device is bolted to the nearside inner guard of our tddi connect in the yard (sorry dont know what its called) but heres a picture, im sure somebody will tell us if its relevent to smokey engines












heres another pic with better idea on position

The MAF sensor is the Mass Air Flow sensor and only measures Air flow.

If you mean Map sensor that is Manifold Absolute Pressure, which will only measure atmospheric pressure but never a vacumn on a TD.

The vacumn lines are only for brake servo, heater/aircon controls and the EGR activation solonoid, which if a big enough leak in lines would cause problems with EGR positioning.


I think The MAP sensor on connects (or early ones and tddi at least), is connected by a small tube near inlet manifold, this looks like a vac tube, but if a vac tube has accidently been connected to this(seen it many times when pipes have all been mixed up) then will cause fuel cut/power loss.

[winterheating]

The P0149 code is fuel timing error on the transits, if on its own and no harsh diesel knock, then its normally because the timing is out slightly, (not the timing solonoid) which would cause power loss, smoke and bad starting... on a TDDI

[Grenadekid]

The strange thing is our transit is a good starter, not smokey,does suffer from power loss but think thats down to the turbo issue and theres no diesel knock Winterheating. Its interesting to get that info on it being a fuel timing error as ive heard nobody mention that before so i will keep that in my head for future reference m8

My f-super has told me the code and description everytime.

My F-super must be a dud because it told me it was the heater sensor circuit
