Weak acceleration sensor
1. Function
The weak acceleration sensor is used to detect and judge the complete vehicle vibration so
as to avoid mistaken misfire judgment and mistaken ignition and effectively control
engine operation. When driving on bumpy roads, due to fluctuation of crankshaft rotation
speed, the angular velocity vector of crankshaft will be influenced by wheel vibration. The
result caused by fluctuation of crankshaft rotation speed is similar to the result of mistaken
ignition of engine. In order to avoid ignition failure due to the mistaken judgment of the
engine electronic control system on ignition when driving on bumpy roads, it is necessary
to record the peak acceleration of the vehicle body with auxiliary sensors and avoid
mistaken ignition on these occasions.

European On-Board Diagnostics (EOBD)
Instructions on EOBD
When the system goes into working condition and the engine runs, the ECM will control
the work of all parts and monitor the parts directly connected with it in real time. When a
part (or several parts) in the system works abnormally, the system will alarm automatically.
Each fault is provided with an unique code. Once there is a fault, the system will output
the code (i.e. fault code) through the diagnostic interface and turn on the “engine
