Anyone?

"" I guess we now have a wiring fault/faults. Have pulled wires on connector and they all appear tight, and there is no sign of weakness when bending them to check if the wire has snapped/come adrift inside the insulation. Next I guess is to check continuity back to ECU.... Can anyone supply the pinouts at the ECU plug from the MAF plug and also the pressure sensor wiring from the intercooler? ""

Want to check out wiring to eliminate it completely

Hi again - it's gone awfully quiet :wink: !
Well have solder, iron, shrink wrap at the ready and checked wiring continuity from MAF plug back just beyond where it enters the harness. Have also done same for MAP but not completely back to wherever it goes as I need the car for a 500 mile drive tomorrow, and it keeps pimply sissing down here :? . Have stripped the insulation back from the main ECU plug, but cannot see any sign of abrasion or a break :( . Anyone know or can point me to the pin numbers on the ECU plug from both MAF and MAP? Lexia still refers to s/c or o/c on wiring ..... so can anyone suggest pointers as to where the break(?) could be? This problem started shortly after I had it regassed (at quick fit), so where should I be looking? As you may imagine I'm almost at my wits end. Lack of power is bad enough, but it is positively dangerous pulling out of junctions and roundabouts with approx 65 bhp on tap!
Any further help will be very much appreciated.
Regards

A lexia showing a wiring short cuircuit does not mean a physical electircal short

Its useually caused by a failed item.. and lexia refers to it as a short curcuit..

Thanks Paul, I am thinking that the most likely culprit at this stage may be the sensor on the intercooler?? Cannot easily get it off. Seems that the intercooler has to come out or at least be moved forward to gain access to the mounting bolt(s)? Brief thought, is that the MAP sensor? If not, where is that item please.....

There isnt a map sensor on a hdi. Theres a flow meter on the air cleaner and boost sensor on top of the radiator..

I dont think its the boost sensor .. the turbo is not electronically controlled.. so unless theres a vaccuumm on the wastegate to close it the turbo will work as its driven by the exhaust gasees..

Have you tried putting the car on ramps and getting under the car and locating the wastegate lever arm and seeing if its free to move? It could be siezed.

Ooh! No I did not know about that. If its not hissing down Tues, will up the car and check the lever. If stiff/seized, better to remove it and get it on the bench, free and clean it? Will have an intercooler anyway if you have one.... Will post back as soon as I've managed to have a look. Thanks, Regards

Whilst it's still raining, have had the lexia on the car again. Reports low flow and the air-flow parameter reads 0. This would indicate both MAF's I have are u/s.... possible but think unlikely for both?? Just in case, anyone got a spare and/or any other ideas? Incidentally it will cruise at up to indicated 80mph on a flat level motorway, but any incline and speed is dramatically reduced. Haldon Hill, for those who know, it was taken at a blistering 25mph. Very dodgy... ,and now the airbag light is on :cry: . At least that should be an easy fix... [-o<

I had loss of power on my 406 and it turned out to be the MAF, I also had it on the C5 and that was the pressure regulator on the HP diesel pump.

If the Haldon Hill is the one down here I shall be going up it tomorrow on the way to Trago mills, and yes it is very steep and very long. long way from Telford though.

Peter, yes that's the one....I have 2 sons in Liskeard and their mum came from Portwrinkle, so know the drive down fairly well - since when the A38 was being converted to dual carriageway 1962ish? - but that was on my velocette 500. The HDI normally romps up it such that the brakes are required to get round the l/h der at the top. Once went up the old telegraph hill after the police closed it due to snow in the late 60's, but thats another story :wink:
Well, the rain is now heavy hail 8-[ ...
I use the Trago in the Fowey valley, fantasy gold mine and always try and visit :lol:

Ah, that explains it. We were down here before they built the M5 so its changed a bit but the A30 is a very nice road most of the time and they keep improving it at the Cornwall end. Driving gently I can get 60mpg+ between here and Trago's in the 406.

We go to the Newton Abbott one which they keep enlarging and improving, super narrow gauge railway which we take the grand kids on - or is it the other way round. We have been to the other two but prefer this one.

Gale blowing here.

Ok, have managed at last to spend time on the car..... Got underneath and located a cylinder 2 inch dia and 1 1/2 deep with 1/4 rod with nuts at end to adjust length. Presume this operates the wastegate and the casting it is attached to is the turbo?... Is this what you mean Paul? It is very free to move, which I guess is bad news? Thought(!) if I connect vac direct to EGR, should this move when engine started?, so if you agree will try tomorrow - the car is supported on logs as I don't trust axle stands on gravel, so should be ok. One other thing. Driving around some distance, not hoofing it, if I then floor the pedal I leave behind a cloud of black smoke - a large cloud, and black! I thought this was just the carbon being cleared out of the cat, esp as when the exhaust fractured a small pile came out of it when tapped on the floor, but I now think that this is the oil I mentioned earlier burning off. I reckon there is seepage from the turbo somewhere.... As always, any recommendations/observations most welcome.
Kind regards

No the waste gate should be loose.. thats good.. now if your brave.. start the car.. let the vaccum build and see if the waste gate is still loose.. it shouldnt be as the vac should be pulling it.. incedentally.. have you actually got a vacc? Disconnect the vac plug on the vac pump on the end of the head and start the engine.. put your finger over the end and see if you have a good vaccumm.. a failed vac wont affect brakes as they are not vac servo so we would never know..

Lots of smoke would indicate an air leak after the maf sensor.. maf measures air comming in and calculates the amount of fuel needed.. if the measured air leaks out then the ecu will effectivly put too much fuel in.. too much fuel for little air will give black smoke.. is the air pipe to inlet manifold not split at the bottom facing downward onto the end of the head.. sometimes a clue by oil gauze over the end...

Couple of things to try there harry..
