P1589 TCU Unable To Control Desired Throttle Angle


Throttle body connection or accelerator pedal connection ,wiring issue ,

Check with Dealer for possible ECM reflash / reprogram to rectify this issue.

The ECM memory should have been rest due to which the calibration of the accelerator pedal has been erased.

Use a scanning tool and calibrate deceleration sensor.

You can do the calibration by clicking Engine and ECT > > special function > > and then click "decleration 0 point calibration" while you do that make sure that your car IGN switch is "ON" and your gear shift is on "P"
