The main function of the oil pressure switch is to monitor the oil pressure in the engine and send a signal to the CPU when the pressure is abnormal, and may control the automatic response of the engine.
Fault diagnosis and troubleshooting:
When there is a problem with the oil pressure switch, such as failure to work properly or false alarms, the driver may experience problems such as engine warning lights, power loss, etc. At this time, the key is to accurately diagnose the root cause of the problem.
