What happens when an electronic actuator goes wrong?
A complete gearbox is required with failures of this nature. If the electronic actuator has failed to open the nozzle ring assembly vanes under acceleration, the turbo will fail to operate efficiently. If the vanes are set to a closed position, it can cause choking of the engine. or overspeeding of the turbine.
What happens if the door lock actuator fails?
If the door lock actuators fail, they will disable the power door lock feature from working. This will require the driver to use the key to lock or unlock the doors, and can disable the power door locks completely for vehicles that do not use a traditional key, such as newer luxury vehicles.
When does an actuator need to be replaced?
This fault can often go undetected during repair and workshop testing, as the fault can only be detected once the actuator heats up. If the turbo connector is knocked or banged, it will break and the whole unit will need replacing.
Can a bad throttle kick actuator be replaced?
One of these components is the throttle kick actuator. Although this is an electrical actuator, it can become faulty, which will require it to be replaced by a certified mechanic. What is the throttle kicker actuator?
What happens when an actuator goes bad on a car?
An actuator can go bad in of two ways; first the electric motor can burn out rendering the unit non-responsive so nothing changes when the temperature or vent mode controls are moved. Next, the plastic gear set will become brittle and break which will sometimes allow the unit to work while making a ticking or clicking noise and then stop.
Can a worn out drive nut cause an actuator to fail?
However, this is a very rare occurrence, and not the mostly likely cause of actuator issues. Much more likely is that the connection to the valve — the drive nut — has failed. A worn out actuator drive nut will not move the valve stem properly. You can see this by removing the center column cover and looking down the center to the valve stem.
Can a faulty door lock actuator be repaired?
The power door lock actuator can be integral to a car door lock repair. If a remote device or unlock switch fails, the actuator may be faulty. Car door lock actuators are designed to lock and unlock a door without the effort of pulling on a cable and rod.
What was the result of a bad VTC actuator?
There were bent and broken valves due to contact with the piston heads resulting from the timing chain jumping teeth which was ultimately a result of the bad VTC actuator. Car died while pulling away from a stop sign and threw a P1129 code on the reader.
