Technical Marea 1.9 jtd limp mode untill temp gets half way?

[richie15]

Hi all, my 2001 marea 1.9 jtd 110 weekend is bugging me when I start the car from cold and drive off the car seems to be in limp mode wont rev past 2200rpm ,but as soon as the temp gauge reads just below half the engine springs into life and runs great untill I leave it cool down then it's back to limp mode. The car starts first time every time no problem apart from the fact you cant rev it, any ideas anyone

My 105 JTD has a similar problem. If I rev it over 3000 rpm before the temp gauge is at the halfway point it goes into limp home mode and puts the injector light on.

Once its been driven like this for about 10 miles it goes back to normal.

If you have a laptop I would try the http://www.fiatecuscan.net/ seems like you need to do a diag the free version will do ya. But first I would try undoing the MAF connection see what it runs like .

It is possible to clean the Maf sensor if youre very careful. You would need some carb cleaner and cotton buds heres a guide http://www.bravo-guide.co.uk/photogal/guidepics/maf/maf.pdf the important thing to remember is squeeze most of the cleaner off the bud. If it works itl save a bit of cash.

All the instructions are on the Fiatecu website , the socket to connect car is down below fuse cover.

I cant find the diagnostic socket on my car. Its not round the fuse box.

If you put the back of your head on the drivers floor and look up you will see it. It will have a cover on. If you had used the search like I have just done you would have come across this. https://www.fiatforum.com/marea/184831-diagnostic-socket.html

 

[madrat]

Its not there

 

[johnson550]

Its not there

Thats the only place I know it to be. According to someone in that link with the pic in before 2001 it was a 3pin socket so I dont know where that is.

on pre 99 model all i could find out is.... under bonnet
diagnostic socket for abs is on bulkhead battery side
diagnostic socket for fuel injection is in front of the power fuse box battery side.
dont know if this is much help to you.

Ok found them I think. small black plugs on ether suspension turret. I'm guessing it means no way to connect to laptop and free diagnostic software.

Maybe someone on the bravo site may know, early bravo is the same as the earlier model marea.

Unless Im mistaken the change would be made from TD 3pin plug and the JTD is the 16pin which has a lot more sensors and things than the TD. I did read somewhere something about the diagnostic socket( somit to do with eec regs) had to be on the drivers side with easy access.
