Question

2005 Land Rover Freelander V6 with engine codes P1628 and P1629, what is the meaning?

Answer 1

P1628 Duty cycle exceeded one second for throttle control Bank 1

P1629 Duty cycle exceeded one second for throttle control Bank 2

You have 2 code that confirms the throttle body motor  is mechanically sticking, The best remecy here is to replace the throttle body motor.
