[Engine] Engine fault, code P1340, jerky accelelaration etc.

[jaakkole]

Hi guys,
I have a Berlingo 1,6 multispace gasoline 2011 with some 90 000 kilometers under its belt.
It has been regularly serviced and has worked without problems.

Now, I have an issue with the car. It begins when I feel weird jerking acceleration and then the engine fault light comes up.
When I park my car, the ventilator fan runs like crazy. When I check the error codes with a code reader it says P1340 and sometimes also P1340P.
When I erase the errors, the car works like new! But after some time (it can be months of days) it comes up again!

When it appeared first time, a year ago, I erased the error code. All problems disappeared and the car worked ok but I suspected that spark plugs can be the issue. So, I got the spark plugs replaced at the annual service. It was ok for long time but few days ago it came up again! I erased the code and it worked OK for 3 days but today it appeared again. Always the same. Jerky acceleration, then the engine fault light, then after parking the fan stays on.

Is there something i could do by myself before taking it to garage? What could be the problem (spark plugs should be ok)? Anyone experienced similar issue?

Thanks in advance, i am delighted to find this forum

Sorry for my bad english, please ask if you need me to try to explain better.

This may help! [There was a link here that I have deleted as it may have given bad advice]

Hi

I just looked through the link provided and could not believe the advice being given  "replace spark plugs every 25 hours of use"

What on earth is that all about?

Looks like poor English translation to me, unlike the OP's post above. The whole site has that 'generic' feeling, and contains no clue to its geographical origin, not even by doing a domain name search.

Note that the little graphic of a Berlingo is no such thing - it's just a generic image of a car.

BTW the fault it gives for the code has nothing to do with spark plugs!

It's a misfire code, could be due to bad coilpack or a fouled spark plug. Worth checking them at least for carbon fouling. The THP engine on the DS3 is well known for it.

Also try disconnecting the MAF when the engine is off then start it and see if it runs ok with it unplugged.

If none of those, maybe something odd like the cam sensor or crank sensor being intermittently bad.

I had a similar occurrence, especially with the fan thing, no idea what the fault codes were as it was under guarantee and went straight to the garage. But the spark plugs were cleaned and eventually changed at the next service.
After talking with the mechanic at the time and the one at the later service, I can only put it down to the low grade/cheap fuel I had been filling up with.

I agree that website showed nonsense though. Generic piffle.

Thank you all for your input! Need to google if I would be able to find and check coilpack, spark plugs and MAF. I am not really a car expert

As your engine is 1.6 petrol, AFAIK it only relies on a MAP sensor rather than MAF. Of course it could be a newer generation engine that has MAF and I am talking out of my back side.

Hi. I've just found this post. I hope it's not to late. Did you manage to find the problem? I have the exact same problem as you. I've got a Citroen C4 Picasso 1.6 VTI. Regards.
