The accelerator on the Mazda 5 sport vehicle is not functioning properly. I kindly request your assistance.

[peakroach]

Hello everyone, may someone kindly assist me in comprehending this matter? The Mazda 5 sport has intermittent power loss during driving, when the accelerator becomes unresponsive. Interestingly, disengaging and re-engaging the gear restores the vehicle's functionality. This phenomenon might occur several times throughout the course of a voyage. Do you have any opinions or insights on this matter?

Postscript: I recently brought my vehicle to the garage, where the mechanic expressed a lack of knowledge about the issue at hand. Consequently, he promptly returned the keys to me, having only examined the vehicle for a duration of 20 minutes.

For the other participants in this forum, What is the year of manufacture or the age of the vehicle?
Could the issue maybe be attributed to a malfunctioning sensor? One possible explanation for the issue at hand might be a malfunctioning pedal sensor, as well as potential faults in the PCM or ECM components. This is only a conjecture.
Does it produce any error codes or messages? Was the mechanic able to inspect the diagnostic codes?
It is advisable to consider seeking assistance from an other technician, since it seems that the previous mechanic may have shown a reluctance to address the issue. Particularly if he abstained from doing a test drive, it might be inferred that he lacked interest in engaging with your business.

Providing comprehensive information on the specific MAZDA model under discussion is of utmost significance.

It is imperative that your MAZDA vehicle undergoes servicing by an Automotive Technician rather than a "mechanic".

The first step entails obtaining the Electronic Control Unit (ECU) data pertaining to Diagnostic Trouble Codes (DTCs), encompassing both pending and permanent engine codes, alongside the status of the pollution monitors.
If the vehicle is equipped with a drive-by-wire system, there should be a diagnostic trouble code (DTC) indicating this.

Thank you for providing the details. The vehicle in question is a 2007 Mazda 5 Sport with a 2L diesel engine. The technician conducted a test drive and had an occurrence of engine failure. However, the mechanic expressed the difficulty of identifying the specific issue, stating that fault diagnosis would be challenging. Additionally, the mechanic attempted to extract diagnostic codes by connecting the vehicle to a diagnostic tool, but no codes were obtained. I concur with your assessment that the individual in question had a disinclination towards engaging in the associated difficulties.

Upon further investigation, it has come to my attention that the act of depressing the clutch pedal alone serves to restore the 'cut out' mechanism, rendering the need to shift gears unnecessary. The phenomenon described is characterized by intermittent occurrences of gear shifting difficulties, particularly during gear changes, while also manifesting occasional instances of normal functioning. Additionally, there are instances when the vehicle abruptly ceases operation while traveling at high speeds without engaging in gear changes.

In order to address the specific needs of your diesel-powered MAZDA vehicle, it is advisable to seek assistance from a reputable establishment, such as a shop or dealership, that employs technicians with Mazda Factory training or ASE Master Technician certification with L2 credentials. Receiving subpar care or inadequate information on your Mazda's worries is quite probable if you settle for anything less.

I appreciate the assistance provided by the technician who recently conducted diagnostic tests on the car. It is noteworthy that this individual is the second professional to confirm that no error codes have been detected.

There was no indication provided on whether these individuals were specifically certified as diesel technicians rather than diesel mechanics. However, it seems that they are not considering all the aspects of your electronic control unit (ECU). Your response might have been more thorough and inclusive. I suggested the services of a proficient diesel specialist who has received professional training. If a someone who is not a diesel mechanic had conducted a brief examination based on the description of your issue, they would have seen a substantial amount of information.

I apologize for your inability to locate someone with more suitable qualifications.

It is recommended to examine the switches located on the clutch and brake pedals.

Do the brake lights activate upon depression of the pedal? Furthermore, it is essential that the device does not activate or display any visual cues while not being actively engaged by the user.

Is it possible to start the ignition of an automobile without using the clutch pedal? Attempt to do the task without engaging the gear mechanism.

Did you happen to peruse the first post? It is possible that you intended to direct your comment to a different topic that you were perusing.

I am referring to the current discussion topic. The switches located on the pedals have the potential to impact several functionalities, such as cruise control activation, vehicle startup, and other related operations. In some automotive systems, when the brake pedal is engaged, it disengages the cruise control function, and in certain vehicle models, it also deactivates the throttle.

However, it is not entirely clear how each of these systems operate and the specific functions performed by the Electronic Control Unit (ECU) in processing the incoming data. It is evident that the material you obtained for online posting was derived from a generalized and comprehensive approach. If the user had a comprehensive understanding of the interplay between the Engine Control Unit (ECU) and the many components responsible for providing input data, and if they had thoroughly comprehended the first answer, it is quite likely that they would not have submitted a comment that may potentially divert the original poster's attention away from resolving their difficulties.
I acknowledge the potential merit of considering several alternatives based on a speculative assumption. However, in order to ensure a more accurate understanding, it is essential to get further information and engage in a more direct question-and-answer exchange with the original poster. By doing so, we may minimize the risk of the original poster embarking on an unfounded pursuit prompted by the aforementioned speculative assumption in your post.

The acronym ASE refers to the Association for Southeast Asian Nations.

 

 

 

 

 

I apologize, but your text appears to be incomplete. Could you please provide more information or

In order to ensure a comprehensive understanding of drive-by-wire technology, it is necessary to familiarize oneself with its intricacies, including the process of modifying sensor input to the electronic control unit (ECU).
In order to demonstrate the potential inaccuracy of your statement, it is suggested that you proceed by driving down a roadway, using the cruise control feature, and afterwards disconnecting the drive-by-wire connection. It is anticipated that no significant outcomes will occur. In order to ensure a safe and efficient operation, it is important to execute a controlled disengagement of the cruise control system, maneuver the vehicle to a suitable location next to the roadway, and afterwards reestablish the connection of the drive-by-wire mechanism. The user's text, "LOL," can be rewritten as "The user expressed amusement
Subsequently, it is possible to start the engine when situated in one's driveway or garage, with the drive-by wire system deliberately disengaged. The throttle body (TB) is factory calibrated to correspond with the percentage input data sent to the engine control unit (ECU), which typically ranges from 12% to 18% depending on the specific Mazda model.
There are no other significant aspects to discuss, since the only function of drive-by-wire technology is to transmit pedal position percentage information to the electronic control unit (ECU).
If there is a malfunction in the drive-by-wire system, the electronic control unit (ECU) will generate a diagnostic trouble code (DTC).

Your assertion is very accurate. I appreciate your response, which criticized me for providing a straightforward and cost-free exam that required just a little time commitment. I trust that they will adhere to your suggestion to seek the services of an other automotive technician. In order to accommodate your satisfaction, I thus declare my intention to refrain from further participation on this forum.

It is at your discretion to decide whether to remain and perhaps engage in discussions or not. I am an active participant in many Mazda forums where I often provide assistance to other members. However, I have noticed that many of them tend to provide unnecessarily convoluted approaches to problem-solving.
I would propose that in future instances, while participating in online forums, it would be prudent to thoroughly review the contributions of other members. If one lacks substantial recommendations, it would be advisable to seek more clarification by asking further inquiries prior to offering speculative responses. Indeed, although the individual act of posting such information may only take a few minutes, the cumulative effect of several individuals engaging in this behavior would impede the expeditious completion of the work at hand.
Upon reviewing your posting profile, it is evident that you should refrain from being too sensitive.
