Lexus IS250 check system light issue requiring repair on Lexus IS250

Some Lexus IS250 owners report experiencing issues with the check system light, which can indicate problems with the Tire Pressure Sensor (TPS) or malfunctioning sensors. If the underlying issue is resolved, such as tightening a loose gas cap, the check engine light may turn off automatically. However, if the light is flashing, it signals a serious problem that requires immediate attention. Additionally, some owners find that switching the system back to the main sensors using the adjustment switch near the steering wheel can help resolve the check system light issue. Troubleshooting these aspects is essential for ensuring proper vehicle function and safety.
