Default 207 VTi 1.4 Petrol - Error Code P11AA

Hello,
I have a 207 VTi Petrol.
The engine fan runs immediately when the car starts and runs for about 5 minutes after the car is turned off.
I've connected a generic code reader, and it has 1 error - code P11AA
The last thing that was done was had the timing chain and tensioner replaced.

I've found this info:
Peugeot 207: hi have a 08 207 fault code P11AA and cooling

Would a BSI reset actual solve the problem?
It's probably the case that there is a software update for this car (it's probably never had one) but will that solve this issue? (I don't want to pay for it if it's not likley to be the problem.
Is it likely to be something else. Some posts are mentioning air leaks / pressure & sensors but I'm not totally understand what they're on about yet.

Thanks, Jon

could try it, but after a recent post it would seem that reseting/clearing it with pp2000/lexia would be my first stop.

have you cleared the code with your obd2 scanner?

Hi not sure if this could help
But I took my 1.4 207SW VTI
In for service and when it came
Back the fan would run continuously
Even on start up and would run for
Ages after pulling up.
Found they had been over generous
When topping oil up also even though
It looked it the oil filler cap was not seated
Properly resolved both SUCCESS JOB DONE.
Hope this helps Kev

I haven't yet.
I wasn't sure if I should keep it there, incase I needed to get it to a garage. I haven't got PP2000 and I was also wondering if that would provide more info.

Now this is one I've read about too....
I've been to it twice and I can't get the filler cap to go on any better than it is. I place it on the top and turn it a 1/4 turn clockwise, which seems to lock it in place. It seems fairly solid. Is there something I'm missing; e.g. do I have to push it down like one of those tops on medicine bottles?

Righty,
So I have just done the following:
1) Clear the error code - There was one Error Code P11AA and one Pending Error Code P11AA.
2) Done a BSI Reset, as described here BSI Reboot Process for Peugeot - United Kingdom | BBA Reman
3) Started it up. All seemed OK.
4) Drove to petrol station and gave it a gulp of fuel. This is about 2 minutes, on a in town A road.
5) Drove off again. Still OK
6) When drove between two junctions on the motorway (I'm going around in a big loop). This was about 2 to 3 minutes. Did most of it at 70.
7) As I came off the motorway I noticed the engine fan was on. The temp of the engine on the dashboard was about 90 degrees as I drove off. The temperature dropped to about 80 degrees as I drove off.
8) Drove back along the A round home. Every time I slowed down for a corner the temp want from 80 to 90 and the fan came on. As I drove off it dropped again.
9) As I got home fan came on again.
10) Turned engine off and fan was on for about 5 minutes until the temp dropped to about 70 degrees.

I'll point out now that I don't often drive this car so I'm not sure how much the temp changes; but that seems like a vary rapid change. It was going from 80 to 90 degrees in a small number of seconds.

I looked at the temp (I think) in the live stream of my reader and it matches the dashboard. See Reader Stream.jpg.
There was a pending error code in the DTC list; P11AA. See Pending.jpg(I have to be honest here, I don't understand what a pending code is. It implies it's a error that's about to happen.)
There aren't any error codes from the Auto Scan. See Code Scan.jpg

Anyone got any ideas?

Generic code readers aren't always able to read the ECU correctly, which means sometimes they miss out info which could be vital to the fault. Especially as some 207 engines use different codes to most generic OBD readers. If you can get the car on Diagbox or Planet, that should give you more insight into the fault.

I'd be tempted to look at the temp sensor, thermostat and coolant.

I've read before that this might be down to a software issue, and the ECU might need updating. If I find the link, i'll post it

Hi,
Hadn't seen the first link before.

From the first link:
>Reset adaptation helped P11AA error of the pressure sensor for
>now is ok. One mistake is a problem that the timing chain is
>pulled and the other probe damage the catalytic converter.
Ok, I don't really understand this one. What are they actually saying they did?
(Apologies if this is obvious but I'm not very much an amateur at this car stuff.)

From the second link:

>However, check first if the sensor is working as it should
>(by monitoring the live data using a diagnostics computer).
So my temperature gauge on the bash reads the same as the ETC.
on the live stream reader. Should I be looking something else as well?

>If that is operating normally, then you need to have the
>engine management software updated.

I'll check coolant level now.
Someone has suggested to take the grill off and cleaning the contacts on the fan. But that was on a 307.

Can I do this myself?
Do I need PP2000 to do it?
How much would it cost for Peugeot to do it?
