If you have a car with a door sensor, you may have noticed that it’s not always working as it should. Maybe the sensor isn’t collecting enough data, or maybe it’s just misreading the signals. In this article, we’ll show you how to fix the door sensor in your car so that it works properly.
What is a Door Sensor?
A door sensor is a small device that sits on the door handle or around the perimeter of the door jamb. When the door is opened, the sensor sends a signal to the car’s computer. This signal is used to activate a function in the car, such as starting the engine.
If your car has a broken or malfunctioning door sensor, you can fix it yourself. There are several methods for fixing a door sensor, and all involve removing the old sensor and installing the new one.
The first step is to remove the old sensor. To do this, remove the screws that hold it in place and pull it off. If your car has a retrofit door sensor, remove the screws that hold it in place and then unhook the wire harness behind it.
Next, install the new sensor. To do this, screws will need to be installed into the mounting bracket on either side of the doorway. The screw should go through both pieces of wood and into the metal backing of the bracket. Once those two screws are in place, tighten them using a wrench.
Now connect the wire harness behind the new sensor to the connector on your car’s computer (or power distribution box).
How to Fix a Door Sensor
If your car’s door sensor isn’t working, you can fix it yourself. Here are the steps:
1. Remove the door panel. In most cases, you will need to remove the door handle and the door panel. If the sensor is located near the hinges, you may also have to remove the hinges.
2. Check the wires. If there are any broken or loose wires, replace them as needed.
3. Reconnect the wire to the sensor. Make sure that it is properly connected to the terminals on the sensor.
4. Test the sensor. Push and pull on the door to see if it opens and closes correctly.
