What are the symptoms of a broken odometer sensor?
1 Answers
The symptoms of a broken odometer sensor are: the odometer will no longer continue to record the mileage. The odometer sensor is the vehicle speed sensor, usually installed near the output shaft of the transmission. The odometer sensor is generally Hall-type. If the odometer is functioning normally, it will intermittently ground the signal line, causing the odometer needle to swing. Nowadays, most car odometer sensors are electronic component-based. The odometer sensor typically has three wires: red, black, and green. The red wire is the power line, the black wire is the ground line, and the green wire is the signal line connected to the instrument panel. The odometer sensor measures the wheel speed based on the principle of speed measurement. According to the wheel diameter, each speed measurement cycle corresponds to one wheel rotation, and the traveled mileage is calculated by accumulating the number of wheel rotation cycles.
