What Is Diesel Generator Camshaft Sensor?

What is a diesel generator camshaft sensor? What role does it play? It is a synchronous signal sensor device and also a cylinder discrimination and positioning device that inputs camshaft position signals to the ECU, serving as the main control signal for ignition control. However, during use, various faults may inevitably occur. How to handle abnormal camshaft sensor signals? Let's hear what the editor from Dingbo Power Generator Manufacturer has to say.

1.Connect to a computer and use a diagnostic instrument for detection: A. Monitor the "synchronization flag bit" when the engine is running. B. Use the diagnostic instrument to monitor the "limp home flag bit".

2.The diagnostic instrument is used to monitor whether there are fault codes related to "camshaft signal error or signal loss" when the engine is running.

3.After unplugging the crankshaft sensor connector, use the diagnostic instrument to monitor the "engine speed". If the diagnostic instrument shows that the "engine speed" value is within an abnormal range, the camshaft sensor signal is abnormal.

4.If an engine with a single camshaft sensor signal cannot start, but an engine with a single crankshaft sensor signal can start, the camshaft sensor signal may be abnormal.

5.Check whether the camshaft sensor and sensor connector are loose, oxidized, or have poor contact.

6.Check whether the lower end face of the camshaft sensor is damaged or covered with foreign objects.

7.Use a vernier caliper to measure whether the air gap between the sensor and the convex teeth of the signal disc is within the normal range of (1.0±0.5) mm.

8.Use a meter to measure whether the resistance between the camshaft sensor measurement terminals is within the normal range of "860Ω±86".

9.Loosen the camshaft sensor connector and use the meter to measure whether there is an open circuit or short circuit from the J1-53 line to the ECU connector.

10.Check whether the installation phases of the crankshaft sensor and camshaft sensor are abnormal.

11.Replace the camshaft sensor for testing.
