[M-R-P]

Driving to my mum's earlier and suddenly... No power, "reduced engine performance" on the screen and full limp mode.
I pulled over, didn't have my phone so had to install torque on the wifes phone. Got the code p1651 intermittent ecu fault.
Cleared the code and the cars been fine since. This doesn't look good as a new ecu ain't cheap and the wife will just want me to break the car :(
I'm hoping all the faffing about I did yesterday has disturbed something. Is this likely? I'll pull it all apart later and look.

I hope this isn't the beginning of the end for the Sweed.

[graemewelch]

if it is the end for your ecu, shark performance have the software so you can fit a used one. so even if the worse happens the big sweed lives to see another day

[M-R-P]

I'm still looking at a minimum of 600 quid to replace an ecu. I haven't got that sort of cash and considering we have another.car to use, the wife will just want rid.

Obviously, ill do what I can to save the old boat but if it comes to it, there's a fair few quid in parts sat outside.

[graemewelch]

600 sounds a lot. i take it youve already spoke to shark.

[JUDGENINJA]

....And what would you replace it with? Any other T5 would cost just as much to run....or are you off to the Starlet forum for good?

[Harvey]

Are the earth points ok on the wings and on the engine.

[M-R-P]

600 sounds a lot. i take it youve already spoke to shark.
I won't go for a reprogrammed second hand one and risk it happening again so it'll be a new one. And I have a pretty good idea what they cost.

....And what would you replace it with? Any other T5 would cost just as much to run....or are you off to the Starlet forum for good?

it may be a daily for a while.
This is merely speculation for now. I'll have to wait and see if it happens again. It could just be a "blip" - I hope.

[M-R-P]

I upgraded the earths a while ago but ill check later.

Just seen this mate, I really hope it's not the ECU, keep us informed with any developments.

[stribo]

Fingers crossed it's only a blip.

[graemewelch]

see what happens when ford stick there nose in lol

[stribo]

Ford make their own ECUs, Volvo use Motronic perhaps they should have stuck their nose in. :P

[M-R-P]

Well the drive home went without a hitch, even though I was giving it some grief.

A bit more googling showed that a mismatch in signals can throw this code. Got me back to thinking I upset something while I was screwing about with it yesterday.

[graemewelch]

that good news. i look forward to reading about the next mod

Oh no, what is it with these ruddy cars and their electronic computer controlled devices! :mad:

They seem to cause no end of faults, holes in our pockets and often without any warning whatsoever. Martin, take out AA Garage cover because after advice from people on here I did to cover myself. You'll have a £35 excess to pay but the AA will cover the rest up to £500 - a big chunk of the cost for a reconditioned ECU or even a new one. :B_thumb:

Put the ECU from the Starlet in there and give it a run. Failing that, take the ME7 out of the Sweed, put it in the Starlet, put a loud exhaust on it, big stereo and give it a chav type respray with a few rattle cans making sure you get that uneven look to it, and then go race around Poole like a tit. ;) :hilarious

[M-R-P]

The bitch did it again!

Coming back from the pistonheads meet, same situation as before - going uphill with the cruise control on doing 70 (ish) mph.

No code stored this time ???

:(

Stopped the car, engine off, engine on roared away in a cloud of tyre smoke. Car working perfectly again.

Bloody thing.

[jdavis]

Very worrying Martin. Do you have vida? That will point you in a better direction to trace the fault
Fingers crossed it's something simple

[y2blade]

Good old Ford :(

[silverhorse]

Hmmmmm. worrying. Is it one of those things that when it happens it can be a bit dangerous? ie you come to a halt in the fast lane of the motorway? Not good if the wife and sprogs are on board:frown:

Hope it is something simple mate. £600 for an ECU change!!!!!:yikes:

[M-R-P]

Actually, it drifts down slowly with no loss of brakes or steering etc, very safe, just annoying.

I have a theory which I'll be investigating.

[M-R-P]

Took the map sensor out tonight. It had a bit of oil on it but didn't look too bad. I put it in the ultrasonic bath for a while and stuck it back in. Time will tell I suppose, if the car still plays up, I'll chuck a new one in there.

If it still plays up... I dunno... anybody want some tasty P2 bits?

[Fubar1977]

Are you REALLY thinking of breaking it?
New ecu is pricey but only 1/2 of what you spent on the clutch.

Just seems a shame to mate...
Unless you're just bored and looking for a new project.

Maybe a T5 engined Starlet :dgrin:

[M-R-P]

Lol, T5 starlet!

New ECU is about 800 quid. But what if I do the ECU and it turns out to be something in the loom (you seen the loom on a P2?) or another sensor elsewhere that can't be tracked down.

Obviously, I'll do whatever I can to keep the old boat alive but I have to draw the line somewhere. There's £2000 in parts minimum in that thing so if getting it going is gonna cost more than a grand...

The missus just wants me to break it and buy her dad's lexus RX300 :( I want a P3 T6 ex plod :D

[Dangerous Dave]

[iancho]

Will be sorry to see it go mate after everything you have done, its the most famous ex plod on here and it has been great watching you make the Swede shine :cry:

[M-R-P]

interesting...

I took the sweed for a quick blast tonight. I didn't get on a position to see if the car was gonna cut out but I noticed something else.

the throttle seems much more "connected" . usually I know what happens when my right foot is in a particular position - I get a predicted power delivery that tails off to the speed I expect. now, I the engine seems to level off, as if it's gone "that's where the pedal is, that's what I'm running to" basically, the throttle position depicts the level of power delivery. it doesn't feel wrong and if I floor it, it's not any slower and if anything, the torque is more progressive.
I'm guessing that this little map sensor has a far bigger part to play in the running of the engine than I initially thought.

can anybody shed any light on this theory?

[AndysR]

Well it's a pressure sensor so if it's partly clogged/dirty it will no doubt affect the pressure readings the ecu receives which will no doubt have an effect on ignition timing and fuelling so chances are you've restored its sensitivity and made the ecu more efficient at knowing and controlling how the engine performs :)

Yeah, that's the conclusion I'm coming to. I always thought it was on-demand fuel, related to the throttle position and boost was controlled by the bcs which got it's commands from the ecu, which got it's information from... oooh... P1651... sensor mismatch... I'm running higher than expected boost (bleed valve), custom maf to turbo, IPD tcv... Think I may have found the route of the problem...?

Here's the comparison I came up with while drinking Fosters in the shower... The car used to feel analogue - like a cable throttle. Now it feels digital and after turning off the DSTC, I had a kind of controlled fun I'd not had in the car before :)

Let's hope this has cleared the limp mode issue too :)

will try and make the boost control sytem sound simple ....

ecu- ecu
bps-boost pressure sensor
tcv- turbo control valve
turbo- turbo

as revs gain, turbo will start to develope boost pressure...
ecu read bps. uses that reading to tell tcv which will activate the wastegate and control boost...
this continuly happens in boost. the circle of boost lol

Says it's a pressure sensor that measures temp too but having had all the charge air system off the car, I can't remember seeing another sensor.

[Dangerous Dave]

Hmmm, found this pic. Not sure if it is relevant to your model year but number 4 is the pressure sensor, 12 is the temp sensor but check out number 18 which is also a pressure sensor.

http://i3.photobucket.com/albums/y64/lockheed2266/MAP3.jpg

no 18 is where itll be if its not in place4. think it was a facelift change thing but i dunno...
just some models had them on the ic oulet and some had them on the ic-tb pipe

[partsforvolvos.com]

the position of the sensors changed between 2002-2003 models.

No. 4 doesn't exist on mine, and the other one is where the map sensor I cleaned is located.

Thanks Dave that's brilliant.
Is there any more accurate/detailed pics? the "77" looks to point to the inlet manifold. I have a feeling it implies it's on the i/c to throttle pipe - which mine doesn't have.

I'll have a rummage about in the bay later and see what I can find.

is this what you mean?
the one right next to the bps
