Automatic transmission throttle valve control cable
Purpose
The automatic transmission throttle valve control cable connects the accelerator pedal to the throttle valve of the automatic transmission. It transmits the movement of the driver pressing the accelerator pedal to the throttle valve, which in turn regulates the air flow into the engine.
Components
* Cable with a metal core and outer sheath.
* Accelerator pedal.
* Automatic transmission throttle and its valve.
* Brackets and clamps for attaching the cable.
Operating principle
* When the driver presses the accelerator pedal, the cable is pulled, moving the automatic transmission throttle valve.
* The throttle valve controls the air flow into the engine.
*Increasing air flow increases engine power, which results in vehicle acceleration.
Adjustment
The automatic transmission throttle valve control cable may require adjustment over time due to wear or stretching. This usually involves the following steps:
* Make sure the car is in park position.
* Loosen the locking clamp on the cable near the accelerator pedal.
* Adjust the cable so that when you release the accelerator pedal, the throttle valve closes completely.
* Tighten the locking clamp.
* Check the accelerator pedal and throttle response for proper operation.
Possible faults
Common automatic transmission throttle valve control cable faults include:
* Cable stretch, resulting in slow throttle response.
* Sticking of the cable in the sheath, causing interference or harshness when pressing the accelerator pedal.
* The cable breaks, making it impossible to control the throttle.
Service
The automatic transmission throttle valve control cable usually does not require much maintenance, but it is recommended to periodically check it for wear or damage. Cleaning and lubricating the cable sheath can prevent snagging and extend cable life.
