How Do I Reset My Electronic Throttle Control Manually: Quick But Easy Steps
Resetting the electronic throttle control manually can be somewhat difficult since it is necessary to perform some steps by counting the seconds.
In any case, before starting this procedure, it is advisable to clean the throttle pedal body.
This is because it is a part that usually accumulates dirt, which makes it difficult to open the air valve.
Step 1. Ignition switch
As we mentioned before, counting the seconds when performing this procedure is one of the most important aspects to restart this device correctly.
Hence, it is advisable to have a stopwatch to obtain a higher level of accuracy. Once you have everything you need, you must turn the power switch ON.
Here it is important to wait exactly 3 seconds and at no time should the engine be started.
The user simply needs to press the accelerator pedal to its maximum capacity, and immediately the accelerator should also be released.
This procedure of depressing and releasing this pedal should be done five times in only about five seconds.
When the above is completed, it is essential to wait seven to ten seconds before continuing.
In turn, cleaning the throttle body will allow for a much more efficient result at the end of this procedure.
This happens because the accelerator modifies its operation since the accumulated dirt represents an obstacle.
So, these modifications in throttle operation may be most appropriate when the throttle body hinders valve operation.
When most of the accumulated dirt in the throttle body is removed, the operation obtained by resetting the electronic throttle control will be more efficient.
Step 2. Accelerator pedal
Once all the above steps have been performed, 10 seconds need to step on the accelerator pedal once more for as long as possible.
This is where the check engine warning light should start flashing. The flashing of this light should be rapid, indicating that the diagnostic test mode or self-diagnostic results have begun.
When the diagnostic test mode is initiated, the user should already release and release the throttle.
Once the user releases the throttle, they must wait a minimum of 5 seconds and a maximum of 10 seconds.
For another 10 seconds, the user should again press the accelerator pedal as far as possible.
When this has been done correctly, the check engine warning light stops flashing rapidly and continues to flash more slowly.
When this happens, the vehicle’s system clears the memory inside the ECU. To continue, the user must release the accelerator pedal, and the ignition switch must also be held in the off position.
Step 3. Start the engine
When each of the above steps has been completed, the user must start the engine again. In this case, the check engine warning light is off when the correct time has elapsed.
So here, the electronic throttle controller reset procedure is completed.
Sometimes the check engine light does not flash quickly or slowly as described in the previous steps.
When that does not occur, it indicates the ECU has not completed the corresponding reset procedure. Hence, it is relevant to go through the above steps again.
Most likely, the user has not contemplated the necessary seconds in each step.
Step 4. Alternative method
There are some alternative methods to properly reset the electronic throttle pedal controller.
It is simply a matter of disconnecting the battery, which can be very efficient for resetting this system and many others within a vehicle.
To disconnect the battery, only the negative terminal needs to be disconnected.
It is also necessary to discharge each corresponding capacitor with the ECU. Here the user only needs to pump the brake using the corresponding pedal.
To realize this operation, it is required to consider the control parameters. Each of these data can be checked from the ECU, and the ranges related to this should be at normal levels.
