What's up, guys? I'm Andy from 1A Auto. In this video, I'm going to show you how to replace a manifold air pressure sensor, also called a MAP sensor, on this 2015 Chevy Silverado.

I'm going to disconnect the negative terminal on the battery. I'm going to use a 10 millimeter socket, extension, and ratchet. Loosen this up. Grab the negative terminal, slide it off, set it aside so it doesn't arc out by accident. Loosen up this worm clamp right here. Also over here is a worm clamp back here in the throttle body. Loosen this one up with the same straight blade screwdriver. I'll take this snorkel off this side, off the air box, and then over here, there's two pipes on each side. There's this little gray lock that you have to push down on the lock and then slide it out. Just like that. You have to do the same on the other side.

This one I'm pushing up from underneath and then slide it up. And I can grab this and just slide it back. Wiggle it a little bit, and the whole thing comes up. You don't have to take this air duct off to do this MAP sensor, but for the camera shot, it's easier to see. I'm going to take a 10 millimeter socket and loosen up this bolt. Take this bolt out. There's a lock on the back of this connector. Just take a screwdriver and get in behind the lock. Pry it sideways. Just like that and push down on the terminal, on the connector, and slide it out. Now we can grab the MAP sensor. Twist it and pull it out.

Take the MAP sensor--just make sure it's cleaned off if there's any dirt on there. Looks good. Can slide it into position, push it down. Take this screw, the bolt, get this started. My 10 millimeter socket, extension, and ratchet and we'll tighten this down. Then going to take a 10 millimeter socket, extension, and a torque wrench. I'm going torque this to 40 inch pounds. Take the connector, line it up, lock it in place, and then lock the connector lock.

Then we're going to slide this into position. There is a little bracket right here that's going to slide into that slot right there. So slide it on the mass on the throttle body first, get that lined up there. Then we can take and slide this on right here onto the air box. That's good. I'm going to take a straight blade screwdriver. Tighten up this worm clamp here on the throttle body, and then tighten this one up as well. Then I'll take these hoses, these are going to clip in. Make sure they lock in place, and the same on this side.

Take the negative battery cable and hook it up to the negative side of the battery. I'm going to take a 10 millimeter socket, extension, and ratchet and just snug this up. Grab the cable, and just make sure it's nice and tight so it won't loosen up.
