P0608 code definition

The P0608 code is related to the control module for the vehicle speed sensor A, and it indicates that there is a malfunction.

What the P0608 code means

When the powertrain control module, or one of the many other modules in the vehicle, detects that there is a malfunction in the vehicle speed sensor output, this code will be stored. Some of the other modules that could detect and store this code include the transmission control module, the body control module, turbo control module, anti-theft module, antilock brake control module, and the fuel injection control module.

What causes the P0608 code?

The following are the main causes for the P0608 code to appear:

What are the symptoms of the P0608 code?

In many cases, the Check Engine Light will come on, but if the code is still pending in the vehicle, this light will not illuminate yet. Many drivers will notice that there are quite a few drivability issues with their vehicle when the code is present as well. The vehicle might be more difficult to shift, and it might have poor acceleration. It could run rough when idling as well.

How does a mechanic diagnose the P0608 code?

Mechanics who are diagnosing the P0608 code will use an OBD-II scanner and connect it to the vehicle’s onboard computer. This will show them more about the code and the issues with the vehicle. They will also reset the code to see if it comes back. If it does, then it generally indicates there is an actual problem. Unlike with other codes, the powertrain control module might actually be the issue for the code’s appearance. It is important to do a thorough diagnosis.

Common mistakes when diagnosing the P0608 code

Often, there are other codes that are present when the P0608 code appears. These could include engine misfires, fuel injector codes, transmission codes, and more. The technicians focus on these repairs, and they do not take care of the P0608 code, which has likely contributed to all of those other codes appearing.

How serious is the P0608 code?

The P0608 code can be a big problem. Not only can the issues it denotes cause other issues with the vehicle, you will also suffer from drivability issues with your vehicle until you have it repaired. It is very important to take your vehicle in for service whenever you notice anything out of place. In addition, you will want to take the vehicle in for regular check-ups to make sure there are no issues that you have missed.

What repairs can fix the P0608 code?

The following are some of the repairs that can be used for the P0608 code:

Additional comments for consideration regarding the P0608 code

One of the interesting things about the P0608 code is the fact that when it appears there is actually a good chance that it is due to a problem with the powertrain control module. With other codes, this is very rare. Regardless of what it is that is causing the code to appear and be stored in your vehicle, it is important that you do not ignore the problem or think that it will go away. The longer you wait the more other issues could crop up with the car or truck. Your best course of action is to work with a qualified mechanic who can diagnose the vehicle and repair the problem so you can get back on the road with the peace of mind you deserve.
