A vehicle speed sensor (VSS) monitors how fast the vehicle is moving. It sends that information as an electrical signal to the truck's control modules, which use it for functions such as the speedometer reading. Delphi supports its sensor portfolio with stringent OE development and product validation methods. Each sensor is tested and calibrated to OE standards for accurate readings.
- Calibrated to match OE: Every unit is tested and calibrated to match the OE part.
- Temperature-stable: Delphi states that the sensor is not impacted by temperature changes.
- Digital output: Uses a designed digital output for maximum signal-to-noise ratio.
- Protected construction: Provides robust, long-lasting sensor protection.
Signs this part may need replacing: an erratic or inoperative speedometer, irregular shifting, cruise control that won't engage, or a check engine light. These symptoms can have other causes, so diagnose the vehicle before replacing the sensor.
Package contents: one vehicle speed sensor. Country of origin: China.
