In this text, we will see what will be the most common speedometer problems for this Citroen Sm, but also their causes.
The counter needle of your Citroen Sm which jumps
It is a concern that remains really tense. If this needle jumps, it's impossible to judge its actual speed . Also, your eyes are naturally captivated by this phenomenon, which is rather dangerous. Some common causes can be found for this concern. Sometimes the wiring between the speed sensor and your dial of the Citroen Sm is deficient. Another possibility is that this speed sensor is defective, you can probably replace it with a new one. More rarely, the concern comes from the axis of rotation of the needle.
The Citroen Sm counter remains at zero
Here is the worry the most embarrassing. The display of this counter which remains at zero is usually linked to a sensor problem. This sensor will not necessarily be defective. Sometimes you just need to apply a specific product for electrical connections to clean it. Wiring concerns are therefore very common in a Citroen Sm. However, it can also happen that the pivot which allows the needle to operate is defective. In this situation, it is complicated to simply obtain this component individually. If the problem is still not resolved, you will probably have to change the sensors of the Citroen Sm. We advise you despite everything to go to a garage to make a real diagnosis.
Approximate speed of the counter
Note that originally, a speedometer is an approximate bit. When driving, the speed displayed is approximately 5% just above the real speed of the Citroen Sm. It is a safety measure that the brands have decided to avoid speed cameras, as well as problems with users. To understand your speed, it is advisable to drive on the roads using an application like waze. For fixed speeds, the application is more precise. Assumed that your speed is clearly discordant, so you probably have a problem with the sounders. You are then advised to have them checked, as you will understand, the problem generally comes from the sensors of the Citroen Sm. Changing a sonar will usually come back cheaper than changing the entire counter. Therefore check the source of the problem before going to any professional.
