[DeRobert]

Here are the solutions for fault code 00546: 1. Clean the throttle body and check if G188 is functioning properly; 2. If it works normally, then the engine wiring harness needs to be replaced. Below is more information about the throttle body: 1. Components: The throttle body unit contains two sensors - angle sensor 1-G187 and angle sensor 2-G188. 2. Function: These sensors determine the current position of the throttle valve and transmit this information to the engine control unit. The engine control unit uses the angle sensor signals to determine the throttle valve's position.
