Which sensor are you referring to? Today's cars generally have more than a dozen sensors. In the 60s of the 20th century, cars had only oil pressure sensors, oil level sensors and water temperature sensors, which were connected to gauges or indicator lights.

In the 70s, sensors were added to help control the car's powertrain, as catalytic converters, electronic ignitions, and fuel injection devices needed to maintain a certain air-fuel ratio to control emissions. In the 80s, anti-lock braking devices and airbags improved car safety. Today, sensors are everywhere.

In the power system, there are sensors used to determine the temperature and pressure of various fluids (such as inlet air temperature, airway pressure, cooling water temperature and fuel injection pressure, etc.); Sensors used to determine the speed and position of each part (e.g., vehicle speed, throttle opening, camshaft, crankshaft, angle and speed of the transmission, position of the exhaust recirculation valve (EGR), etc.); There are also sensors for measuring engine load, knocking, fire failure and oxygen content in exhaust gases; sensors to determine the position of the seat; sensors for determining wheel speed, road elevation difference and tire pressure in anti-lock braking systems and suspension controls; To protect the airbags of the front occupants, not only more collision sensors and acceleration sensors are required, but also sensors such as occupant position and weight are needed to ensure their timely and accurate work. Sensors are also needed to add sensors to the side volume, overhead airbags and, more sophisticated, side-mounted head airbags provided by the manufacturer. Braking systems have become an integral part of automotive stability control systems as researchers use collision avoidance sensors (ranging radars or other ranging sensors) to judge and control the car's lateral acceleration, the instantaneous speed of each wheel, and the required torque.

Hello dear, the following answers have been made to your questions, which is such a scumbag, help you sort it out! If the Civic sensor is broken, it needs to be replaced in time to avoid causing vehicle failure. Vehicles have a variety of sensors, different functions, different installation locations, and the frequency and reasons for failure are also different; If the sensor fails, it will affect driving safety if it is not replaced in time.

Here's a little bit of extra knowledge.

The types and functions of the sensor are as follows: 1. Intake pressure sensor: reflects the change of absolute pressure in the intake manifold, and provides a reference signal to the ECU (electric control unit of the engine stool) to calculate the duration of fuel injection; 2. Throttle position sensor:

Measure the angle of throttle opening, and provide it to the ECU as a reference signal for oil cut-off, control of fuel-to-air ratio, and correction of ignition advance angle; 3. Inlet air temperature sensor: detect the inlet air temperature and provide it to ECU as a calculation of air density; Coolant temperature sensor: detects the temperature of coolant collapse and provides engine temperature information to the ECU; 4. Crankshaft position sensor:

Detect the crankshaft and engine speed, and provide it to the ECU as a reference signal to determine the ignition timing and working sequence; 5. Oxygen sensor: detect the oxygen concentration in the exhaust gas, and provide ECU as a reference signal to control the fuel-air ratio near the optimal mass coarse residual value (theoretical value); Detonation sensor: Installed on the cylinder block to detect the deflagration status of the engine, it is provided to the ECU to adjust the ignition advance angle according to the signal.

The position of the Civic sensor is as follows: 1. Oxygen sensor: The oxygen sensor is installed on the exhaust pipe, which is used to monitor the combustion gas after combustion to judge whether the combustion of the engine is sufficient, and whether the mixing degree is too thin or too concentrated;

2. Wheel speed sensor: the wheel speed sensor is generally in the front brake disc, it is mainly to collect the speed of the car to judge whether the car has signs of skidding, so there is a special sensor to collect the wheel speed of the car to complete this work, generally the cherry tree is installed on the hub of each wheel, and once the sensor is damaged, ABS will fail;

3. Water temperature sensor: the water temperature sensor is installed next to the thermostat, converts the cooling water temperature into an electrical signal, increases the amount of fuel injection or increases the ignition advance angle when the temperature is low, and prevents deflagration at high temperature, and delays the ignition advance angle;

4. Intake pressure sensor: generally installed on the side of the throttle, the intake pressure sensor, as the name suggests, is to induce a series of resistance and pressure stool changes with the different speed and load of the engine, and convert it into a voltage signal for ECU to correct the fuel injection amount and ignition timing angle. If the ridge or obstacle is blocked, it will cause problems such as ignition difficulties, unstable idling, and weak acceleration.

The 10th generation Civic is an electronic sensor, and the 10th generation Civic oxygen sensor is located on the exhaust pipe, and the front and rear ends of the three-way catalytic converter. Due to poor combustion of the engine, carbon deposits are formed on the surface of the oxygen sensor, or deposits such as oil or dust enter the oxygen sensor, which will hinder or block the external high-gear air from entering the oxygen sensor, so that the signal output of the oxygen sensor is inaccurate, and the ECU cannot correct the air-fuel ratio in time.

The 10th generation Civic oxygen sensor is located on the exhaust pipe, and the three-way catalytic converter is at the front and rear ends.

Due to poor combustion of the engine, carbon deposits are formed on the surface of the oxygen sensor, or deposits such as oil or dust enter the silver search part of the oxygen sensor, which will obstruct or block the external air from entering the oxygen sensor, so that the signal output of the oxygen sensor is inaccurate, and the ECU cannot correct the air-fuel ratio in time. Carbon deposition is mainly manifested in the increase in fuel consumption and a significant increase in emission concentration. At this point, if the sediment is removed, normal work will be restored.

The oxygen sensor cannot be cleaned with any chemical liquid. Otherwise, it is easy to damage the sensor and make it not work properly. If there is carbon buildup on the surface of the oxygen sensor, it can be cleaned with a metal brush and then blown clean with compressed air.

The black soot indicates that the mixture is too thick. If the signal of such an oxygen sensor is not normal, or inactive, it is recommended to replace it.
