On average, the cost for a Mercedes-Benz S450 Speedometer Sensor Replacement is $114 with $19 for parts and $95 for labor. Prices may vary depending on your location.
As its name implies, the speedometer displays your vehicle's real-time speed. Most speedometers are electronic. An electronic speedometer measures vehicle speed with the help of a speedometer sensor. This sensor, usually located at the transmission, detects the drive shaft's rotational speed. The sensor delivers a corresponding series of pulses to a computer, which then turns these pulses into the numerical figure the speedometer indicates. So when the speedometer sensor becomes faulty, the speedometer becomes unreliable.
Your replacement speedometer sensor needs to be specific to your make and model, or else it might be inaccurate. A VIN is required to ensure the correct match.
There’s no need to be proactive with your speedometer sensor, as your car will quickly let you know when it fails. When the speedometer sensor malfunctions, the Check Engine warning light should come on, and your vehicle's cruise control will stop working. The speedometer may also stop working, or it may become noticeably inaccurate.
A speedometer sensor measures the rate at which the vehicle’s driveshaft is rotating; this data is sent to the vehicle’s computer, where it is converted into a number and displayed on the speedometer. When the speedometer sensor fails, there is no line of communication to your speedometer, and you won’t be able to view how fast you’re driving.
