Left Power Back Door Position Sensor

This smart sensor helps your Toyota’s powered tailgate open and close smoothly and safely. It monitors the left-side movement/position of the back door and sends a clear signal to the control unit, so the system knows exactly where the tailgate is at all times ✅.

Why This Part Is Needed

A power liftgate needs accurate feedback to prevent over-travel, slamming, or stopping at the wrong point. This sensor is a key “eyes and ears” component that supports normal operation and anti-pinch safety.

How It Works

As the tailgate moves, the sensor reads position changes and converts them into an electrical signal. The control module uses that data to manage motor speed, stopping points, and smooth closing force 🔧.

Symptoms of a Faulty Sensor

If the sensor is failing or broken, the liftgate may behave unpredictably, including:

• Stops halfway or reverses for no reason
• Won’t close fully or won’t latch
• Beeping/warning light, stored fault codes
• Jerky movement or safety function triggers too easily

Driving with a bad sensor can lead to a stuck tailgate, damaged hinges/struts, or a liftgate motor working too hard ⚠️.
