oil pressure sensor on chevy silverado
The Chevrolet Cruz oil pressure sensor is installed on the right side of the water pump. The engine oil pressure sensor checks the engine oil pressure. If the engine oil pressure is too low, there will be a warning lamp on the instrument panel to remind drivers. The minimum oil pressure of Cruz cannot exceed 130 kPa, which means 130 to 350 kPa, but the water temperature must be measured at 80 ℃, and the normal standard value should be about 250 kPa. If the Cruz oil pressure sensor is damaged, it will not cause the engine to shake. However, if the oil pressure sensor is damaged, it must be replaced in time, or serious consequences may result. The pressure sensor is mainly a device of mechanical structure, and the deformation of elastic element is used to indicate the pressure. However, this structure is large in size and heavy in weight, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure sensors have also emerged. It is characterized by small volume, light weight, high accuracy and good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors are developing towards miniaturization, with low power consumption and high reliability.
If the instrument display code 89 of Chevrolet Cruz indicates that the oil pressure sensor of Cruz locomotive is faulty. The following is the specific introduction of the oil pressure sensor: Function: The automobile oil pressure sensor is an important device for detecting the oil pressure of the automobile engine, and the detected data helps to control the normal operation of the engine. Working principle: connect the amplified pressure signal to the oil pressure indicator through the signal line, change the current ratio of the two coils inside the oil pressure indicator, so as to indicate the oil pressure of the engine. The pressure signal amplified by voltage and current is also compared with the alarm voltage set in the alarm circuit. When the voltage is lower than the alarm voltage, the alarm circuit outputs an alarm signal and lights up the alarm lamp through the alarm line.
The engine fault light will flash on the instrument panel in the car, and the driving force is insufficient and the acceleration is weak. Oil pressure sensor: generally speaking, the car will have two oil pressure sensors, one is high pressure and the other is low voltage. No matter whether the high voltage or low voltage is damaged, the engine fault lamp is set on the instrument panel in the vehicle.
