Horn doesnít work at all/alarm acting up, also getting boost sensor CEL
Hey guys, I was hoping to get some advice about how to figure this out for my 04 speed Miata. Not really turbo related problems, figured I'd ask anyways.
Horn and Alarm
My horn used to work just fine. It would honk when I pressed on it and also when I double-tap the lock button on the fob. That was the only sound that it would make when I locked it with the fob.
Recently, however, the horn makes no sound at all when I press on it, and for the most part, there is no sound when I lock the car. The fob does work Ė the car locks and unlocks and the lights flash when I do so, but no sound. Occasionally when I open and close the door (and occasionally when I lock it with the fob) I hear a very high pitched beep, as if coming from the alarm itself. For the most part however, there is never any noise. If I press the panic button on the fob, the lights start flashing but there is no noise. Whatís weird is that I can still set off the alarm (makes the same high pitched noises as I mentioned before) by shutting the trunk really hard or opening the door when the car is locked. There is a little red LED on my steering column that flashes when the car is locked and responds whenever I use the fob to lock/unlock. Iím not sure if this is aftermarket or stock for MSMs.
Iíve checked all of the fuses and they are all working. Iíve looked into valet mode and that doesnít seem to be the solution to it. Iíve searched for answers for the last few weeks and Iím starting to run out of ideas. If anyone knows anything that might work, please, let me know.
Check Engine Light
Another issue that itís been having is that it keeps spitting out the P0106 (Manifold Absolute Pressure) code to me. I bought a new OEM boost sensor and installed it and it worked for a while. In the next few times that I drove it the CEL sure enough came back. I checked the new sensor and it all of the hoses near it and they all seem to be okay. I clear the CEL often now, and it comes back in the next few times that I drive. I havenít had any issues with performance whatsoever, I just want to know why it keeps giving me this code.
Also, both of my fog lights went out. Checked every single fuse in both fuse boxes and they were all good. Not sure if related at all.
..Itís also possible that this is all just happening because it is so cold recently.
If anyone has any clue about what any of these might be, any help would be appreciated. Thanks!
