丰田雷克萨斯节气门位置传感器 89452-30150 精确反馈油门信号

When Toyota or Lexus experiences sluggish acceleration, unstable idle, jerky shifts, or check engine light, likely a dirty or aging throttle position sensor causing inaccurate throttle signal. This sensor precisely monitors throttle opening and transmits real-time position data to the ECU to ensure proper fuel injection during acceleration, deceleration, and idle. OEM number 89452-30150; fits Camry, Corolla, RAV4, and Lexus ES, RX models. Installation: disconnect negative battery first, clean throttle body surface, ensure sensor orientation matches original, and perform throttle position learning reset with a diagnostic tool after installation.
