Dodge Magnum vehicle speed sensors missing issue on Dodge Magnum

Some Dodge Magnum owners report experiencing issues with the vehicle speed sensors, which can lead to a malfunctioning speedometer. Common causes include a faulty vehicle speed sensor (VSS), a defective speedometer, or underlying electrical issues. Error codes such as P0501 may indicate problems with the VSS, while a check engine light often accompanies a faulty speed sensor, triggering trouble codes like P0500. To diagnose these issues, owners are advised to use an OBD-II scanner to check for error codes related to the speedometer or VSS. Additionally, fault code P0501 could result from various factors, including problems with the sensor harness, poor electrical connections, or a malfunctioning Engine Control Module (ECM). It is recommended that owners investigate these components to effectively address and resolve any speed sensor-related problems.
