Gear Indicator Fault Has been on my dash ever since I got the car, sometimes it goes away for a while then I will see it for a few days. what is it referring to? some1 mentioned that its user generated by not putting it fully into gear. I mostly see it when shifting into park

Thanks for adding the code. This is called a transmission range sensor.

More than likely this needs to be replaced but I am attaching the info below on how to test this for this code.

Here are a couple of guides that will help with completing this testing:
