Title: Code 59 ......
Post by: I_want_an_Omega on 28 May 2010, 10:41:33
Hi,

I'm getting a "fast flickering" ECU light.

Turns out its a Code 59 - which is:

59   Intake Manifold Valve 1 Voltage Low

I think this is the rear multiram control valve - but any ideas?

It's only started doing it today and that was after I opened her up after a cold start. The light now comes on as soon as the car is started & its defo flickering - with the light being on 95% on and 5% off.

I've had the plenum off to the the cam covers so suspect that I might have disturbed something.

Thanks

Valve 1 is the rear one, correct.

If you've had plenum off, its an easy one to forget to plug back in.  I'm sure we all have at some point  :-[

A voltage low error would be a short circuit as far as I know. If it was disconnected he would get a "voltage high" error.

Please correct me if I'm wrong, but that's my experience and logic so far.

Not necessarily, but would need to check it...

I think the low side of the solenoids are switched by the ECU so voltage low = disconnected.

(ECU expects 12v on the line, grounds it to energise solenoid).
