ford speedometer driven gear
Ford speedometer driven gear its reflects the prompt signal of external temperature. When the external temperature is lower than 4 ℃, the yellow light will be on, and when it is lower than 0 ℃, the red light will be on. Nothing else. If the red light is always on after you start the engine and the outside temperature is not that low, your outdoor temperature sensor is broken. If the outdoor temperature sensor is damaged, the air conditioner will not work, and the engine fault light will be turned on.
This lamp is a transmission fault lamp. If the lamp on the instrument panel is on, it indicates that the transmission has failed. Generally, only cars with automatic transmissions have this lamp, while cars with manual transmissions do not have this lamp. Because there are almost no faults in the manual transmission, there are no computers and sensors on the manual transmission. The automatic transmission has a tcu, which can collect data from various sensors. After processing, the transmission can be shifted by the actuator. Without tcu, the automatic transmission cannot work normally. There are three kinds of automatic transmissions commonly used in automobiles, namely at transmission, cvt transmission and dct transmission. Dct transmission, also known as double clutch transmission, is a popular transmission at present. This gearbox has two sets of clutches, one for controlling odd gear and the other for controlling even gear. The structure of double clutch transmission is similar to that of manual transmission. This gearbox has only one clutch and one shift control mechanism more than the manual gearbox. The double clutch gearbox has fast shifting speed and high transmission efficiency, which is very suitable for use with small displacement turbocharged engines. Among the three transmissions, the double clutch transmission has the highest failure rate.
Remind:The gear on the dashboard refers to the automatic transmission fault warning light, indicating that the transmission is faulty or the transmission oil is lower than the normal range, or the oil needs to be replaced. It is recommended to go to the repair shop as soon as possible. The gearbox mainly refers to the gearbox of the car, which is divided into two types: manual and automatic. The manual transmission is mainly composed of gears and shafts, and the variable torque is generated through different gear combinations; the automatic transmission AT is composed of a hydraulic torque converter, a planetary gear, a hydraulic pitch change system and a hydraulic control system. The dashboard of an automobile is a device that reflects the working conditions of various systems of the vehicle, including: fuel indicator light, cleaning fluid indicator light, electronic accelerator indicator light, front and rear fog light indicator lights and warning lights.
