Different catheter-based ablation techniques may be used and they generally fall into two categories: (1) cold-based procedures where tissue cooling is used to treat the arrhythmia, and (2) heat-based procedures where high temperature is used to alter the abnormal conductive tissue in the heart.
Speed sensors convert the pulses created by the contact between the magnet and sensor ring through a coil attached to the sensor. This voltage is passed along to the controller. The controller counts the number of pulses to determine wheel speed and evaluates whether the ABS system should intercede to control braking.
this can signal a problem with the transmission speed sensor as well when the sensor isn t working the speedometer can t tell what your speed is this makes driving dangerous as you don t know what speed you are traveling at the best you can do is guess
