Toyota Highlander speedometer not working with ABS and check engine lights on on Toyota Highlander

Some Toyota Highlander owners report experiencing issues with a non-functioning speedometer accompanied by illuminated ABS and check engine lights. These problems may stem from a malfunctioning Vehicle Speed Sensor (VSS), which is essential for relaying speed data to the vehicle's systems. Additionally, issues with ABS sensors located on each wheel hub could impact both the ABS system and speedometer functionality. A faulty Engine Control Module (ECM) has also been noted as a potential cause for the ABS light activation and speedometer malfunction. Furthermore, some owners find that poor electrical connections, open or short circuits, or a failed VSS could contribute to these issues. It is crucial for owners to inspect ABS sensors for visible damage or debris and to test their resistance according to manufacturer specifications to ensure proper operation. Addressing these concerns through careful diagnosis and inspection is recommended for resolving the speedometer, ABS, and check engine light problems in the Toyota Highlander.
