How to install the sensor of Beiqi Wangwei 306474 engine code table?

1. Open the engine compartment cover, loosen the air cleaner cover, loosen the throat strap of the throttle intake pipe, and remove the whole engine intake pipe and filter cover from the engine compartment. The purpose of this is to reach the position of the speed sensor and remove the speed sensor plug and fixing bolt conveniently.

2. Remove the buckle and plug of the speed sensor: pry the elastic buckle of the speed sensor aside with a small screwdriver and unplug the plug of the speed sensor. Only by unplugging the plug of the speed sensor first will it not be blocked when removing the fixing bolt of the speed sensor.

3. For the final disassembly of the speed sensor, a ratchet wrench and a universal socket adapter can be used. Because the universal adapter can change the stress angle, it is more convenient to disassemble. Of course, if the hand is small enough and long enough, it is feasible to use a suitable ring wrench directly.

4. Loosen the fixing bolt, shake the sensor socket and take out the speed sensor. What needs to be reminded here is that after the speed sensor is disassembled, there will be a hole that goes straight through the inside. This hole should be temporarily plugged to prevent small objects from falling into the gearbox.

5. When installing the speed sensor, apply some grease to the sealing O-ring of the speed sensor. At present, it is convenient for the speed sensor to be pressed in place smoothly. After the sensor is pressed into place, tighten the fixing bolt, insert the plug of the speed sensor to the bottom, and press the elastic clip into the clamp. As this buckle is very small, it is difficult to buy, please be careful not to accidentally lose it. Next, resume the installation of other components and complete the replacement of the speed sensor.

6. The vehicle speed sensor is a sensing device for detecting the vehicle speed. The ECU of the driving computer uses various signals including the vehicle speed sensing signal to control the idle speed of the engine, the locking of the torque converter of the automatic transmission, the shift logic, the switch of the engine cooling fan, cruise control and other functions. If the speed sensor is damaged, it will definitely have a greater or lesser impact on the work and normal running of the automobile engine.
