Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

When the ECM (computer) sends the TCM throttle position information that is unreliable, DTC P1890 will set. In order to determine the cause you are going to need to do some testing. I have enclosed the test steps in the links below.
