68334877AA is suitable for Dodge automobile oil pressure sensor

One of the characteristics of automobile technology development is that more and more components adopt electronic control. According to the function of sensors, they can be classified into sensors that measure temperature, pressure, flow, position, gas concentration, speed, brightness, dry humidity, distance and other functions, and they all perform their respective duties. Once a sensor fails, the corresponding device will not work normally or even not. Therefore, the role of sensors in automobiles is very important.

Air temperature sensor: detect the intake air temperature and provide it to ECU as the basis for calculating air density;

Coolant temperature sensor: detects the temperature of coolant and provides engine temperature information to ECU;

Knock sensor: it is installed on the cylinder block to detect the knock condition of the engine and provide it to ECU to adjust the ignition advance angle according to the signal.

These sensors are mainly used in transmission, steering gear, suspension and ABS.

Transmission: there are speed sensors, temperature sensors, shaft speed sensors, pressure sensors, etc., and steering devices are angle sensors, torque sensors and hydraulic sensors;

Suspension: speed sensor, acceleration sensor, body height sensor, roll angle sensor, angle sensor, etc.

Let's get to know the main sensors on the car.

The air flow sensor converts the inhaled air into an electrical signal and sends it to the electronic control unit (ECU) as one of the basic signals to determine the fuel injection. According to different measuring principles, it can be divided into four types: rotating vane air flow sensor, Carmen vortex air flow sensor, hot wire air flow sensor and hot film air flow sensor. The first two are volume flow type, and the last two are mass flow type. Hot wire air flow sensor and hot film air flow sensor are mainly used.

The intake pressure sensor can measure the absolute pressure in the intake manifold according to the load state of the engine, and convert it into an electrical signal and send it to the computer together with the speed signal as the basis for determining the basic fuel injection quantity of the injector. Semiconductor piezoresistive intake pressure sensor is widely used.The intake pressure sensor can measure the absolute pressure in the intake manifold according to the load state of the engine, and convert it into an electrical signal and send it to the computer together with the speed signal as the basis for determining the basic fuel injection quantity of the injector.
