Alfa Wiring Diagram Needed - Urgently

**Guy Mayers** · 30-03-2013, 17:04

Hi all, I need a wiring diagram for the UK Market 1992 164 Cloverleaf with the Bosch Motronic ECU part number 0 261 200 130.

I've spent a week looking for a fault that's causing a no spark at the plugs and haven't managed to find anything yet.

I't almost at the point where I'm going to rip the entire loom out and start again and write another year of use of the car off.

If there is anyone out there with a car that's up and running with this ECU fitted I might well come visit with the current ECU to see if it fits & runs!

I found this diagram online this afternoon and I think it matches the loom I pulled from the donor car but there's a sensor I don't recognise yet. It's the third one from the left on the top line, annotated "M15" - does anyone know what this little bugger is? Or if I need it?

Cheers

Guy

Hi Guy,

found it in my alfa repair manual. Motronic 3.0 V6 Scheme. M15 is called "Verdampfungs Elektroventil" => Vaporizer electrovalve ?!

Think it is used to keep petrol fumes back in the fuel system ...? Excuse the translatio ...

Thanks! I'll have to check the remains of the donor car and see if it's still there. I wonder if the engine will fail to run without this little item?

Andrea agrees with your translation by the way!

I asked the same question when rewiring my 24V Guy. Seems it's ok to cut it out..

It wouldn't affect the running I'm sure.
It will be the solenoid valve on the vapour recovery canister which seals the tank when the engine is switched off & opens the canister to the plenum chamber when the engine is running.
