Pug 206 Woes

Just got in from the garage having nearly frozen to death trying to sort out Mrs Nashers Peugeot 206. Its a 1.4l petrol.

She called after work today to say her car wasn't running right, was down on power, and the check engine light was flashing on and off.

When I got there I found she'd had the problem at the end of her journey on the way in this morning, but just presumed it would put itself right, apparently it had done this twice in the last few months and had been OK after being left all day. Of course she hadn't said a word to me.

I took it for a short test drive and found that yes it was down on power, and running rough on tickover so towed it home for a better look.

It runs rough on tickover but sits there 'hunting' up and down, giving it a bit of throttle appears to make it run sweeter, but it is down on power.

I tried all the quick stuff like checking all the connectors, making sure the air filter wasn't blocked etc etc, and even replaced a bit of rubber hose on the breather system that could heve been letting in air where it was perished. I dropped a new set of plugs in, although strangely the ones I took out were all a nice even Tan colour, showing no signs of trouble. I've discounted a fuel supply issue and the coil pack because of this but could be wrong.

I'm leaning towards a Lambda sensor problem now, and will try to pick up a couple of generic ones tomorrow that are only about £15ea. Might as well replace both whilst I'm doing it, they are the originals which are 8 years old and have done 95K miles.

Whilst typing this I've thought it could be the Throttle position sensor, but am not going back out in the cold tonight. Not sure if it has a crank position sensor or wheel at all.

What do you think?
Am I on the right lines?
Or have I missed something obvious?

Nasher.

What kind of age Nasher? I've been out of the car game to long but I remember pug engines are great (specially Diesels). Is it a carb, a single point injector on to a carb or is it a full injection model?

Never forget stripping a pug engine down with one of my mates when I was a teenager. We thought we'd broke it when we found the cylinders weren't connected to the block

If injecton have a look at the tickover bypass valve for the hunting (if it has one) but wouldn't be down on power because of this.

The Lambder sensors might need replacing as I understand life can be as low as 60,000 miles, but experience has told me that these usually go wrong pretty fast so with the other incidents happening intermittently, it makes me wonder.

TPS would normally create a flat spot during acceleration. So unless this is happening I would discount this.

Can you interragate the ECM and find out what the fault is?

I've changed coil packs on both 1.1's and 1.4's, very common.

yep you can if you have the correct gear. but if you are in the RAC (other services are avalible) get the good lady to call them and say it is down on power and she thinks it is going to cut out at any point. the first thing the RAC will do is plug in the lap top and read off the fault code. and find out what is wrong.

If it is simple fix then get them to "recover" her back home. you sort out the part and the problem sorted. well fingers crossed.

Thanks Guys.

The car is a 2001 model 1.4l.

I'm beginning to regret towing it home myself, but it was only a few days ago she had to get the AA to tow her home after the clutch cable snapped. At least that was an obvious fault that only took me 1/2hr to put right.
Its been so reliable up until now, we've had it from new but can't afford to change it at the moment.

The Generic £15 Lambda sensors are harder to get hold of now locally, although they are on ebay in Gosport but the seller isn't answering any questions about me collecting in the evening.
Direct replacement parts are available easily at @£50ea, but I'd rather spent an hour splicing 8 wires than spend £70 more.

The £70 saving also gives me the oppertunity to try the coil pack first which is available for @£50 and I can sell the old one on ebay if it proves to be OK.
I'll be trying to pick one up tomorrow, but as we've only one car now I'm running family about mornings and evenings and trying to make up the hours at work as well.

Nasher
If it's the same seller as the one I used last year for the Kia, he is based in the back of a carpet warehouse (renting space). I found him contactable and collected on a Friday afternoon. If I can help you out Nasher by popping down and collecting them for you?

BTW the first sensor I connected up didn't work and threw up more fault codes than I care to remember. He replaced it without any trouble.

with any luck its the coil pack theyre crap! a friend had a 206 which conked out at regular random intervals for a 2 year period and no garage could ever fix it.
when it finally died i was asked to look at it,
Coilpack had failed, since changing it a year ago it hasnt missed a beat
aparently the insulation or screening fails and confuses the hell out of the ecu with voltage spikes long before they die totally.
bad news it they can jigger the ECU too but they are fixable.

I guess it's prob the TU3JP motah, as used in loads and loads of things.

The coil packs are prone to go, and when they do, feed back into the ECU and cook it. On Vix's 306 (same motah though), the coil went, noticeable as a misfire when cold which went when the motah warmed up. There is a "preferred" brand replacement - can't remember which it is though.

If the light is on, TBH I'd (paying if necessary) to plug it in and see which sensor is flagging a failure.
If you start plugging/unplugging things, the ECU will log all of em and you won't know which is the real error.
I believe you can get leads & software off ebay cheaply as well.

Does it run OK right from cold start, and then get worse after a minute or 2 - the Lambda sensor isn't used until it warms up slightly.

Finally, Vix's car had similar symptoms intermittently - it went ultra rich even when warm. Turned out to be the ECU coolant sensor was saying -40C as the motor warmed up, so the ECU was going max rich - enough to stall the car.

TBH for £50 i would replace the coil pack anyway, there is a reasnobale chance its either past its best or the cause of the problem.
i had a look on the PUG forum and it does recommend replacing a certain make of pack as a matter of course to avoid the possibility of wrecking the ECU.
