I have a problem with dyna 2006. Bike is starting well, but cant ride it. It is choking, caughing etc.
Computer shows throttle sensor and map or manifold sensor.
what i already replace:
-ecm
-map sensor
-throttle sensor
-ecm connector
-injectors
-fuel pump and fuel filter (were totaly shitty)
-there is No 5V on ecm pin 14
-checked connection between ecm and sensors
Mine dit exactly the same.
But only when we were riding 2 up. Alone no problem.
HD service told me throttle position sensor, which I didn’t understand, because alone, no problem.
Anyway , I waited 6 months for a new sensor, HD service changed it, and it was exactly the same.
I told them again and again that in the first place I could not understand it should be the throttle position sensor.
Well long story short, they changed the chief of the service department.
I told the new one about the problem, so they put the bike on the stand and strapped it down like there were 2 on it.
And bingo , the problem was a cable going from the back and underneath the motor.
It had a little cut which touched the metal when under pressure.
I had looked at all the cables but this one is really hard to see.

Looks like pin 26 is sensor ground, might be isolated from chassis ground. When checking sensor 5V you might need to put the meter neg lead on pin 26. If you don't have the 5V at the sensor the ECM will not get a signal from the sensor.

Digital grounds used in the ECM will be isolated from the chassis ground to prevent the voltage regulator from passing current to the ECM through the ground. If you have no 5V sensor voltage none of your sensors would be working.
