Vehicle Speed Sensor: Service and Repair

REMOVAL






1. Disconnect the battery ground cable.

NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 mi) or more to relearn the strategy.
