Car sensors play a crucial role in modern vehicles, enhancing safety and efficiency.
Common Types of Car Sensors
- 1. Oxygen Sensor (O2 Sensor)
- 2. Mass Air Flow Sensor (MAF)
- 3. Tire Pressure Monitoring Sensor (TPMS)
- 4. Engine Coolant Temperature Sensor
- 5. Crankshaft Position Sensor
- 6. Wheel Speed Sensor
- 7. Parking Sensors
How Do They Work?
Sensor Type | Function | How It Works |
---|---|---|
Oxygen Sensor | Measures oxygen concentration in exhaust gases. | Uses a zirconia-based element that generates a voltage proportional to the oxygen content. |
Mass Air Flow Sensor | Measures the amount of air entering the engine. | Uses a heated wire element that changes resistance as air flows over it. |
TPMS | Monitors tire pressure. | Uses pressure sensors inside the tire to relay data to the driver when pressure is low. |
Engine Coolant Temperature Sensor | Monitors engine temperature. | Uses a thermistor that changes resistance based on temperature. |
Crankshaft Position Sensor | Detects crankshaft position to optimize engine timing. | Uses magnetic or Hall effect technology to read the crankshaft’s position. |
Wheel Speed Sensor | Monitors the speed of the wheels for ABS and traction control. | Emits a signal indicating wheel speed; typically uses electromagnetic induction. |
Parking Sensors | Assists drivers while parking. | Uses ultrasonic waves to detect obstacles and provide auditory/visual alerts. |
