Trunk Ajar Sensor

ShadeBoy · 2025-09-18T16:53:59-0400

All - In putting my roof down today I learned that you definitely want to have the "hook" in the closed (retracted) position first. On my first attempt to close the trunk, the "hook" was hitting something. I learned that there is a latch (of some sort) mounted in the trunk behind the rear window. After putting the hook in the closed position, I was able to close my trunk properly. (I know it was closed properly because the deck lid was flush with the silver body panels). Regardless, the "Trunk Ajar" sensor was going off for the entire trip home. I suspect that I created the problem when I first tried to close the trunk. When I got home and looked inside the trunk, I did not see anything that caught my eye. The latch that is inside the trunk (mounted behind the rear window) may be a little off kilter but I can't say for certain.

Does anyone know how the sensor is engaged or disengaged and what may be out of alignment? (I did not used to have this problem until today).

Thanks.

The trunk ajar sensor is built into the latch, and normally indicates that the latch is not fully engaged. I would never drive the car with that light on.

Hmm. As I said, I am confident that the deck lid was closed all the way. Maybe the latch wasn't fully engaged but the deck lid was closed. Maybe I need to raise the whole latch assembly to further engage the bar that holds the roof in place. I'll take another look. Thanks.

You can unplug the harness to the latch the alarm will stop sounding. The truck lock will still work with the button or fob. You just loose the ability to know if the trunk is truly closed.

Thanks. I'll try to fix it properly first but good to know this info.

I can add that the sensors do go bad. I have had a couple of cars with the same problem. To test the latch is good you can take a screw driver or similar round object and place it in the latch where the deck lid latch connects. Push down hard to allow the latch to lock. To release the test bar just hit the fob or dash button or the release it. If the alarm is still sounding with the latch locked your best bet is to replace the latch assembly to remedy your problem. I have several good latches if you do require one.

Great. Thanks. Probably won't get to it until Monday but I appreciate it.
