Durametric Diagnostic Question

[JFP in PA]

When you activate the VarioCam units, you should hear a click, after which the idle may change a bit; but it should not die, and you should see the cam values move on the Durametric display.

When I actuated bank 1 nothing happened to the engine while running, I can hear a slight click I think when the engine isn't running.
When I clicked Bank 2 start while running, she sputtered hard and coughed out.

Another odd occurance, when I turn on AC she runs better and the CEL goes solid. If I turn it off CEL stays solid for about 2 minutes then starts fladhing again. Is it the sensor not adjusting, and the AC kicks up idle closer to the existing default no sensor running range?

I found what pins go where (25 on Connection) and how tho test the connection and the sensor. Yup climbing the learning curve, thanks for helping me narrow it down. If you had to guess statistically, what direction should I test first? start at DME and move towards sensor or start at sensor going back to DME? Just wanting to rule out most likely candidate issue first.

Direction is unimportant as you would be looking at continuity, which is a loop. Once you confirm continuity, meaning that the wiring is intact, next look at resistance, which should be very low. I would also look at checking the wiring to a ground source, looking for a possible short.

Okey I went about testing a little differently, but I think I accomplished what I need to know. If someone can verify (JFP help!)

We tested the actual sensor using a Power Probe III,

Sensor itself had three prongs.

With ignition on pin 1 = 12v, Pin 2 = 4.5v, pin 3 = good ground

Went to ecm, checked against manual and all data for proper prongs and wire color
We pinned into the wires post ecu, since we dont have the test adapter.
Double checked on all data to solenoid as Brown/ red and brown / black

Resullts
ignition off brown/red = 12v and brown/black = 0v
ignition on brown/red = 12v and brown and black = 1v

So it seems the electronics is all connected?

still get these off durametric, I am at a loss, still no bank 2 cam variation
did I right, or am I missing something?

Thanks in advance guys!

Crap wrong photos attacheed below and it wont let me edit
let me try again...

Shoot wrong screen captures, only the last screen capture is valid, the no motronic module error was when the cable disconnected. I will show screen shots tomorrow...

Mate, did you work this one out? I was gold on another forum that ROW cars don't monitor cam deviation for bank 2 (I guess no sensor or part of DME programming?). That wouldn't be the cause for your Durametric not showing bank 2???
