What are the main types of automotive sensors?

There are several main types of automotive sensors: 1. Throttle position sensor; 2. Intake pressure sensor; 3. Crankshaft position sensor; 4. Air flow sensor; 5. Knock sensor; 6. Temperature sensor; 7. Engine speed sensor; 8. Vehicle speed sensor (SPD). The function of sensors is to convert various operating condition information during vehicle operation into electrical signals and transmit them to the computer, ensuring the vehicle remains in optimal working condition. Solutions for diagnosing faulty automotive sensors include: 1. Checking whether the sensor is damaged; 2. Inspecting the wiring harness, connectors, and relevant circuits between the sensor and the electronic control unit.

As a long-time enthusiast of car modifications, I've found that there are really a wide variety of car sensors, which can make the car run smoother and safer. Common ones include temperature sensors, installed near the engine to measure coolant temperature and prevent overheating that could damage the engine; oxygen sensors located in the exhaust pipe to monitor the air-fuel ratio, saving fuel and being eco-friendly; wheel speed sensors on the wheels, working with the anti-lock braking system to prevent skidding; position sensors like the crankshaft position sensor inside the engine to ensure precise ignition timing; as well as air flow sensors, knock sensors, and pressure sensors, among others. Some are also linked to the emission system, affecting annual inspection results. When driving, don't overlook these sensors. If a sensor fails, issues like increased fuel consumption or engine shaking may occur. It's best to regularly check them at a shop with a diagnostic tool to keep the car in good health.

As an average car owner, I often encounter sensor issues, and there are quite a few types. For example, there are temperature sensors that monitor heat, usually located near the radiator or engine, which tend to trigger alarms during hot summers; oxygen sensors are in the exhaust system, helping control the air-fuel mixture combustion—if they fail, fuel consumption can skyrocket; speed sensors are near the wheels, enabling ABS and stability control systems to function; position sensors coordinate engine operation, tracking crankshaft and camshaft positions; others include air flow meters and knock sensors. When these sensors malfunction, the car might not start, run unevenly, or worse, pose serious safety risks—like wheel speed sensor failure causing skidding. Last time, a minor sensor issue cost me a hefty repair bill, so I recommend getting them checked every six months to avoid bigger problems.

I've worked at an auto repair shop before. From a functional perspective, automotive sensors can be categorized into several major types: those monitoring engine health include temperature sensors, knock sensors, and mass air flow sensors; safety control sensors consist of wheel speed sensors (for ABS and TCS) and impact sensors (triggering airbags); emission management sensors encompass oxygen sensors and NOx sensors; there are also position sensors like crankshaft and camshaft position sensors ensuring precise ignition. They're mostly located near the engine compartment or chassis, directly connected to the ECU control unit. When these fail, warning lights illuminate, the car may shake, or experience poor performance - an OBD-II scanner can retrieve trouble codes. During maintenance, cleaning connectors and avoiding oil contamination can extend their lifespan, saving you from expensive repairs.
