Hi all, I have a 2008 Patrol ZD30CR with an unresponsive throttle.

The engine will start, idle, and high idle even works but the pedal will not respond.
Have replaced the throttle position sensor entirely and the throttle body actuator without any luck.
Have disconnected the batteries to reset ECM as well.

Anyone had this before? Had thought maybe the ECM had a misfunction but I think i'd have other problems if that were the case.
Any help appreciated
