The crankshaft position sensor (CKP) detects the engine speed, crankshaft position signal and TDC signal on the compression stroke of each cylinder. The TDC signal is the primary signal for controlling the fuel injection and ignition timing. CKP, the same as mass air flow sensor, is the crucial sensor in the centralized control system.

The vehicle speed sensor (VSS) is the crucial component of the automotive electronic control system. The sensor converts the vehicle speed data into electrical signals while driving and transmits them to the computer. This process controls other functions such as engine idling speed, automatic transmission torque converter locking, automatic transmission gear shifting and cruise control. The VSS keeps the vehicle in the best working condition.

Automotive electronic control systems generally follow the workflow of perception, control and execution. Sensors which work as perception units acquire the system information of operating condition. The control unit deals with the sensor signals, then sends the output control instructions. Finally the execution part accomplishes the corresponding instructions.

Testing is an essential link of engine development. Standard testing methodologies help to troubleshoot failures of the automotive sensors. Well-behaved sensors are vital for daily driving. If automotive sensors have problems, the engine can't work in order. Here are some testing methods for common car sensors.

The working car engine generates the data of several systems. The information cannot be read directly by the car computer. They must be converted into electrical signals that the computer can recognize. Car sensors do this work. They convert the light, electricity, temperature, pressure, time and other data into electrical signals, then input them into the car computer system to calculate and analyze, then check the car condition.

There are various sensors in the car engine. We know about the automobile's operating condition through the water temperature. The sensor converts the cooling water temperature into an electrical signal. The vehicle ECU receives the feedback signal (water temperature), analyses it, and issues commands (signals of the fuel injection and ignition timing correction).
