The car's rotational speed sensor measures the number of rotations the engine is turning. RPM means the number of rotations the engine makes per minute times 100. The number of rotations is passed on by the sensor to the tachometer in the dashboard. In this way, the driver can see when it is necessary to shift gears in order for the engine to perform optimally. Most modern cars can already shift around 2000 rpm. When the engine is running below 800 rpm and is in gear, the car will stall because there is not enough fuel and air in the engine.
Rotational speed sensor broken
Sensors are very sensitive to defects and malfunctions, as is the speed sensor. When the rotational speed sensor is broken, this will be indicated by a number of symptoms. The first symptom that will occur is the Check Engine light coming on. This light illuminates when the computer system detects incorrect information being received. In this case it is important to read out the system to see where the fault is. Another symptom is losing power while driving. When a fault in the rotational speed sensor is found, the vehicle will enable safety settings and reduce power to protect the engine. In addition, the revs are read incorrectly and the engine cannot perform optimally. This will cause the car to lose power. A final symptom is not being able to start the car. When the rotational speed sensor is broken, it cannot send signals to the car's computer. This may result in the engine not being ignited and the engine therefore unable to be started.
Replace rotational speed sensor
In the event of a defect in the speed sensor, it is important to replace it as soon as possible so that you can continue to drive safely and optimally. Replacing the rotational speed sensor is very different per car. In some car models, the timing belt and surrounding parts such as the coolant reservoir or the oil hoses will therefore have to be removed. Would you rather leave this job to the garage? Then make sure that you purchase the rotational speed sensor at an affordable price from Winparts and deliver it to the garage yourself. This often saves you a lot of costs!
