AEM EPM Flat Trigger Waveform


Ranbie

Recommended Posts

Evening,

I'm trying to fault find an AEM COP on my Link G4+ for a B18c.

 

The issues I'm having are;

-No timing light pulses while cranking.

-A flat 4.3v trigger scope event.

-No RPM signal.

 

What I've checked;

-Coil Test. (all work fine with timing light)

-Confirmed all pins on sensor side are correct.

-All pins on ECU side are as per Adamw's Illustration from another topic.

I have consolidated every reference that I've been able to find on these forums to help me but I'm still unable to get a normal signal on the scope.

 

Will continue to look for anything out of the ordinary but would appreciate some help!

I would think you don't have ground or 12v at the sensor.
