Hy everybody! Does anyone know what P1590 Engine running signal, high input (permanent)  error means on my 2.2 DTI diesel mig? Please help me with any advice, because I am stunned by this error. It has any relevance with the charging, because my values are 13,90 V in idle, and 14,00 V at 3000 rpms? The consumption is ~ 600 mA with the engine stopped. Thanks in advance!

Hi well im not to sure, dose it affect anthing else, do your light go bright and dim with revs, if so it could be the volt reg on the alternator, or the charging relay in the engine management box think its the green 1, allso if you have the radio on listen to the radio and if you hear a whine on radio with the engine, it the alternator bushes going, hope this help

Thanks rusty. I come with fresh measurements results, so:
- when I close everything, the multimeter shows there is a fluctuating consumption as between 1,12 A and 0,60 A, and after 30 seconds it shows 0,30 A for 2 seconds and then stabilizing at 0,26 A or somethimes 0,23 A, and stays like that;
- I also measured with the CCR 2006 off  the bay, or with the ECU disconected, or with the tow relay disconected, or with the radiator like relay disconected and it is 0,23 A also; also with all of that disconected;
- I also cleaned all the battery contacts and the contacts from the fuse box located in the engine compartment, including the 80 Amps fuses located upon the battery and the showed 0,27 A  :-?
- I measured the alternator battery circuit and the results are like this: alternator (alt.) plus and alt. mass is 14,43 V; alt. plus and turbo mass is 14,44; alt. plus and A.C. conduct is 13,70 (maybe is the alloy used in the conduct); alt. plus and battery minus is 14,35  :-? ; battery plus and alt. mass is 14,04; and finnaly at the battery terminals I have from 13,90 to 14,04 without any consumers. So the big question is why I don't have 14,44 or at least 14,40 at the battery terminals  :-?  :question
- and when I leave the mig in the parking lot for 3 days or more, it seems like the battery is exhausted, or when I start several times in succession, since the battery is new with a 80 A current  :-?
- what should I do to find out what is my consumer with a 0,23 A; should I remove any fuse from the foot compartment and measure or shoul I remove any relay from the engine or foot compartment  :question :-?
Any ideas will be wellcome and I thank you in advance, because
I am at the second battery and I would be angry, especially as winter comes 
Yours,

Hi m8 sound like u have somthing draining the batter or a sell is on its way out, take the bat of and check that there is not a drain by resistance remove the lcd fuse or the display fuse, make a reading, see what u get, if its no resistance  remove fuse 1 at time and see whick fuse is making it high resistans is fine but low is no good best to do it with the buzz on the meter when in the fuse box ok m8 hope that help

[secarianu]

Ok, I will measure that way, but if someone knows what are the common consumers that can generate that consumption of a total of 0,23 A ?

[secarianu]

Hello everyone! Here I come with new measurements wich look like this: I pulled each fuse one at a time and when removed fuse 7 the multimeter showed a consumption of 0,00 A from the 0,25 A wich I had. At the fuse 7 we have the accesory relay and it switches itself off after a total of 5 minutes, so I guess the case is resolved, unless the relay is defective. What do you guys think?

[secarianu]

Doesn't anybody know? Any advice will be greatfull!

[secarianu]

I am coming with new questions, because the problem is not resolved 
So, rustym95 you are saying that is an CHARGING RELAY in the relays box? Besides the voltage regulator? Interesting! THe GREEN ONE? Can you tell me exactly wich one is it or shall I take a look in TIS?
