What sensors are there on the engine?

1. Crankshaft sensor accurately calculates crankshaft position, which is used to calculate injection time, injection quantity and rotation speed.

2. When the camshaft sensor judges that the cylinder and crankshaft sensor are faulty, it is used for limping home (temporary operation).

3. The air temperature sensor measures the intake air temperature, corrects the fuel injection quantity and timing, and prevents overheating.

4. The boost pressure sensor monitors the intake pressure, calculates the intake volume and intake temperature, and combines them with the intake temperature.

5. The cooling water temperature sensor measures the cooling water temperature for cold start and target idle speed calculation. At the same time, it is also used to correct the injection advance angle and overheat protection.

6. The * * * rail pressure sensor measures the fuel pressure in the * * * rail pipe to ensure the stability of oil pressure control.

7. The throttle position sensor sends the driver's intention to the controller ECU.

8. The vehicle speed sensor provides the ECU with the vehicle speed signal for vehicle drive control, which is provided by the vehicle.

9. The atmospheric pressure sensor is used to correct the fuel injection control parameters at different altitudes and is integrated in the ECU.

There are also cylinder pressure sensors, knock sensors, and some sensors that monitor CH and NO emissions after treatment.
