Why is the throttle needle not moving?
2 Answers
The reasons for the throttle needle not moving are: 1. Problem with the fuel float: Take it to a repair shop to connect the two wires of the fuel float. If it still doesn't move, check the wiring and the dashboard; 2. Problem with the fuel gauge wiring: After removing the dashboard, use a multimeter with a large needle to locate and test the corresponding fuel gauge wiring on the dashboard. Modern car dashboards have various indicator or warning lights under the mask, such as coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, high/low beam indicator, transmission gear indicator, anti-lock braking system (ABS) indicator, traction control indicator, airbag (SRS) warning light, etc.
When I first started driving, I encountered an issue where the throttle needle didn't move, which was quite unsettling. Later, I learned that this problem could be caused by several factors. The most common cause is a faulty throttle position sensor, which is responsible for detecting how much you press the accelerator. It could also be due to a blown fuse related to the system, which can be found in the car's fuse box—checking and replacing it usually solves the problem. Another possibility is aging or poor contact in the wiring behind the dashboard, which prevents the signal from being transmitted. For older vehicles, the control unit might malfunction. At the time, I tried checking the fuse myself and found it was blown; replacing it fixed the issue. However, if the throttle doesn't respond, it can be dangerous as it affects your ability to judge speed changes. So, I recommend stopping to troubleshoot first rather than rushing to drive—safety comes first. Additionally, during regular maintenance, have a mechanic inspect the dashboard system to prevent unexpected issues through preventive maintenance.
