Toyota Lexus Vitz Vios Corolla Vehicle Speed Sensor 83181-12040 Mileage Signal Transmission

When your Toyota or Lexus shows a non-working speedometer needle, cruise control failure, or automatic transmission shifting hesitation and upshift delay, the vehicle speed sensor may be aging or damaged, failing to reliably transmit mileage data to the ECU. This sensor normally converts wheel speed to electrical signals for real-time speed data, ensuring accurate gauge reading, smooth transmission shifts, and cruise control operation. OEM number 83181-12040; also compatible with 83181-12030 and 83181-42010; fits Toyota Vitz, Vios, Crown, Lexus and many models. Installation requires disconnecting the battery negative and ensuring the sensor seal with the transmission housing is intact to prevent leaks or signal interference.
