Frequent error codes linked to 247-5231 usually stem from internal gear wear or a faulty feedback sensor. If the motor clicks but doesn't move, the internal stepping mechanism is likely seized. Replacing with a brand new 119-0633 unit restores communication with the ECU immediately.
2. How to test if the 6-wire throttle motor is faulty?
Measure the resistance across the coil pairs. If any circuit shows "open," the motor is burnt. Also, check the harness for continuity. If the engine fails to reach high idle, the 1190633 motor sensor may be providing incorrect voltage back to the controller.
