What Causes the Engine and Skid Light to Illuminate?
3 Answers
When the anti-skid warning light on the dashboard illuminates during driving, it usually indicates that the road surface is excessively slippery. This is normal as the vehicle's anti-skid system automatically activates, and the warning light will turn off after passing through that section. If the anti-skid warning light remains constantly lit, it is likely that there is a malfunction in the vehicle's electronic stability system. It is recommended to first stop and turn off the engine, then wait a moment and restart to check. Additional information: If the warning light turns off, it is mostly due to a system error. If the warning light remains on, it is necessary to visit a 4S shop or auto repair shop to read the fault code and determine the exact issue.
I recently encountered a situation where both the engine and skid control lights came on while driving. It happened suddenly on the highway with the car shaking slightly. Possible causes could be issues with the engine control system, such as a faulty oxygen sensor causing abnormal emissions, or worn spark plugs affecting ignition, which might indirectly trigger wheel slip and activate the skid control light. Another possibility is a common electronic control unit failure, like an ECU problem affecting the vehicle stability system. I first pulled over to check fuel levels and tire pressure to ensure no leaks, then drove slowly to a nearby repair shop to scan for trouble codes. This issue shouldn't be delayed as it might damage the engine or cause accidents. Immediate attention is recommended to avoid higher repair costs later.
As a car enthusiast who often works on my own vehicle, I know that the engine light usually comes on due to insufficient fuel pressure or intake pipe leaks, while the skid light may indicate a wheel speed sensor malfunction or false activation of the vehicle dynamic system. When both lights illuminate simultaneously, it often signals a systemic issue. For example, engine faults causing power fluctuations can destabilize the vehicle and trigger the stability control light. My first step is checking fuses and simple connections, then using a diagnostic tool to read data streams for specific error codes to avoid guessing and unnecessary part replacements. Regular maintenance and sensor cleaning can help prevent such problems.
