Technical Key in hand, engine still running!

[stevendrums24]

Hi all,

I have a 2.3 120 2007 Ducato that has developed a rather strange problem after changing the alternator.

Last week I noticed the idle revs were up at around 1100 and the battery light came on. Quick test with the multimeter and loan behold the alternator wasnt outputting. Yesterday I got round to changing the alternator.

When I got it fitted and fired her up, she fired up first time and stopped when I took the key out. So I proceded to fast on all the plastic trims/covers etc.

Since then I have some very strange issues. Sometimes the immobiliser light comes up on the dash and it wont start. Then when I do get it to start everything looks fine but I can take the key out, dashboard goes off but the engine still runs. Then I get three error codes:

U1706 - Unknown
P0111 - Intake temp sensor 1
P0101 - Mass or Volume air flow A

I have started to look at the wiring looms at the areas that I've possibly disturbed but I cannot see anything wrong.


Has anyone get any ideas of what the fault might be?
Any help is greatly appreciated!



Thanks

Steve

Have you accidently removed the cable to the throttle valve. its on the inlet manifold and when the key is switched off it closes and shuts the air off and stops the engine. (just a thought)

Earth strap to body from alternator? Prone to breaking or bad connection? has it got a good clean connection?
