What is the reason for fault code 00546?

[AlyssaLynn]

Cars are equipped with numerous sensors, which display different fault codes when they detect issues. When fault code 00546 appears, the corresponding measures are: clean the throttle valve, check whether G188 is functioning reliably, and if it is working normally, replace the engine wiring harness. More information about automotive fault self-inspection is as follows: 1. The angle sensor 1-G187 and angle sensor 2-G188 in the throttle unit are used to determine the current position of the throttle valve and transmit this information to the engine control unit. 2. The vehicle fault self-inspection terminal and automotive fault diagnostic tool (also known as a car decoder) are portable intelligent automotive fault self-inspection devices used to detect car faults. Users can quickly read faults in the car's electronic control system and, through the LCD screen, display fault information to promptly identify the location and cause of the fault.
