P1619 error

[drdjekill]

Hello, I have a sudden problem with my jet. A 2011 RXT-X 260. And I have a P1619 error (ThrottleActuator-Adaptation of uppermechanical limite failed Damaged).
I changed the throttle body, the engine harness, the steering harness, RH Accelerator sensor, the ECM. Nothing removes this error. I tried to reset with the BUDS, same. In fact, it was when I tried to reset the throttle body that this error appeared on the new ECM.

I need help please.

I found the same issue on the Green Hulk forum:

I found it too, but my problem is not solved with his solution.

bummer, yeah I didn’t get how a year newer different ECM fixed the problem

All sensors and functions that affect and help to control the TB and engine air flow can cause the TB to get confused where it thinks it is out of position which can throw this code. This includes the IAT, fuel injectors, MAP, engine temp sensors, etc., low compression, and even leaky valves. Very rarely is it just the TB or TPS.

What you don't mention is how it is starting, idling, revving, running, etc. which is very helpful to diagnose.

I still found my problem. It was the air temperature sensor on the intake. As soon as I unplugged it and cleared the faults, my throttle started working normally again and the error code did not come back. Thanks
