Toyota Corolla 1.4L/1.8L Neutral Switch 88969648 Gear Position Sensor Replacement

This neutral position switch (gear position sensor) directly replaces Toyota Corolla OEM 88969648 and 8454052050; universal compatibility. It monitors transmission gear position and sends signals to ECU to control idle, starting, and shift logic. Fits Toyota Corolla 1.4L and 1.8L models, including older and newer versions. Post-installation, resolves gear engagement shudder, starting difficulty, or unstable idle, especially cold-start; if vehicle won’t move after shifting, or gear indicator shows errors, or you need to press accelerator to start, likely worn-out—replace early to protect transmission.
