206 Breakdown!

[BusEngineer 7]

Just had to pick up the other half on a trailer after her 206 cut out on her way home from work

 

Its a 55 plate 1.4, it will start and idle (sometimes roughly other times fine) but whenever you touch the throttle it cuts out, wont even drive an inch!!

 

Any ideas?? should be able to get it on diagnostics tomorrow, but im after ideas in the meantime

I would hazzard a guess at a faulty map sensor.

Any idea where i find the Map sensor??

It'll be bolted onto the inlet manifold on the left or the right side dunno precisely ..

Well i towed it to a local garage and they've tried it on thier diagnostics and there are no faults according to the computer!!!

 

They have had another diagnostics fella out to it and he said plugs, these have been swapped and its still the same!

 

Were lost!! they're currently changing the throttle body to see if that helps

 

anybody come across this before??

[welshpug 1,661]

ahhh, many 206's have a motorised throttle body, i.e drive by wire.

 

the pedal itself still has a cable, but its very short and goes directly to a sprung throttle potentiometer that sits in the engine bay, doesn't go anywhere near the throttle body itself.

Right time for an update

 

I left the 206 at a garage a mate of mine owns and after the two diagnostic checks that cam up clear, he changed the throttle body for a second hand one, and the problem cleared up, my missus used the car for a day with no problem, BUT this morning just as she was getting to work it started doing it again so it needs trailering back again!!

 

I hate modern cars!!

 

It just wont rev past 2000rpm, its like its hitting a limiter or in limp mode

 

So now im really stuck, any ideas?

 

Im thinking of the following:

 

Check earth lead condition and clean connection at gearbox

Replace coilpack (as im told its very common to fail on these)

Disconnect ECU and check for water ingress

Possibly replace stepper motor (but this has just been changed as its in the throttle body)

Change to Bosch spark plugs (although its ran fine on NGKs for 6 months, and my mechanic has put new NGKs in 2 days ago)

 

So what do you think??

the coil pack is a common problem they seem to dislike ngk spark plugs
