My check engine light came on, and the oil change place said it indicated the air intake sensor. He plugged it back in and the code went off, but then came back on after driving down the block. That sensor is a bit loose, and doesn't snap in, which I presume it should. I tried plugging it back in myself, but the light still comes on. I've got a big trip this weekend... can I put it off until Monday, or is this something I need to fix immediately? I was going to temporarily tape it, but now the light still comes on even right after pushing it in... 2015 Promaster 1500, btw.
