Title: mk1 engine idle hot
Post by: ovi on April 30, 2013, 09:49:45 AM
I have search the forum and I couldn't find a topic about.
my ford galaxy 66kw start on cold with 1000 rpm and stay there even on hot .
I have check the codes and I have nothing on engine.
I dont know where is situated the sensor for water?
Can be from the injection pump after they have change the belt? They didnt fix the idle for the pump?
What I can do ?
Thanks

Hi Ovi, and welcome to the forum! The idle is controlled entirely by the ECU so you almost certainly have a sensor giving defective readings - I would start by looking at the coolant sensor for the ECU as this has been known to cause your problem. It also rarely gives a fault code but just packs up!

Thanks for the answer.
Do you have a photo or just tell me where is situated?
 Will start with this sensor untill the vcds arrives

it is not the same motor, mine looks like this
http://forums.tdiclub.com/showthread.php?t=279936 (http://forums.tdiclub.com/showthread.php?t=279936)
and in the front on the tube coming from the radiator i have 2 sensors one with a brown color the first and second is a black color , both with 4 cables and square connector.
i have disconnect the brown one and no change on the motor, then i disconnect the black one and the gauge of water doesn't work.
i have bot the brown one and change it and still my Rpm stays at 1000.
now on Thursday i will buy even the black one and change to see if i have a result.

Oops I sent you the Mk 2
The Mk 1 as I think you have already found on the front of the engine.

yes both sensors are in the same tube, one brown color and one black.
i need the black one to change because the brown i change it and no effect.
I will make some photos and upload them.

What I found with vag com was that my engine runs at 903rpm
And searching on internet I find many people have this rev on Ahu.
yesterday I had make it at 882rpm with the vag. Thats the minimum I could get.
thx
