I have an 05 Avalanche, when first purchased the dealer mentioned it had been traded in with an airbag light on. They had since fixed it however about six months in, the light came back on. It's been on about a year now and I finally got around to having a friend run the DTC code which threw a B0103, Front End Sensor 2 Performance (Right). I found the part # 10370149 however before ordering a non-returnable part wanted to check the wiring to the sensor as I've already tested moving the driver seat and connectors. The left front sensor has GM part # 10370149 however to my surprise, the right and possible culprit shows GM part # 15103522.

 

 

 

I haven't been able to locate part # 15103522 in the forum, gmpartsdirect or anywhere online. Is it possible they installed the wrong sensor or does anyone know if this is an acceptable replacement? Pics of both sensors are below, I appreciate any and all possible help.

---- UPDATE ---

 

 

 

For anyone experiencing DTC B0103, parts guy confirmed #15103522 was the old part number. Not sure why they changed, perhaps due to it known to be junk however I purchased #10370149 at dealer for $107. Pulled fuse under hood and removed negative battery cable. Due to screw location on sensor, ½” socket wouldn't fit so used a 10mm combination wrench to remove old sensor and replace with new. Replaced fuse, re-connected battery cable, Airbag light off and problem solved!!

      What a wonderful result! Great story telling to. You are quite multifaceted sir.  I'd keep it. Four is my limit too and yet we have five as well. One assigned the 'salt car' to do all those tasks you hate to ask of your 'Save for Good" crowd. 😉    Don't forget the antifreeze.    The Iron 4.3 is a favorite of mine.

      Ancillary parts to the lower intake and connections went together without issue.   There was a brief pause when I leak-tested the fuel lines and injection system. Fuel was spraying all over. Lovely. O-rings weren't sealing the fuel lines to the spider, and inbound line was leaking at schrader valve, leaks at both flange nuts. It's moments like those when you just want to set fire to the whole shop, and be done with it. I was mostly enjoying the project up until that point, and was tracking to an agenda of having a running Blazer and a cold beverage in hand by dinnertime.    I found some larger Viton o-rings for my spider and some grease to get them to seat. One leak solved. Swapped fuel line Schrader core for old core. Still leaked. Swapped entire valve for old valve. Leak solved. Nudged the flange nuts a little tighter on the connections. Another leak solved. I could cycle the key / prime the pump and the intake was staying dry.    Reassembled the upper intake, with 10,000 vacuum lines, and filled the cooling system with water* (this is temporary, I'm not done with the cooling system yet).   Showtime!!   Cranked it over and smoke billowed, it was running rough. CEL illuminated and began flashing. P0300 and I somehow tripped a code for the TPS sensor, voltage low.    There's nothing as unrewarding as a vehicle that won't run (and produces the same code/problem) after hours of research and work.   Clearly I was in over my head. Was the timing off, did I stab the distributor incorrectly? Is the new distributor bad? With my limited OBD 1.5 data stream I really don't have a lot of parameters to see. The engine was pulling mad timing again (flooding?).   Think, Atlas, think.   1-6-5-4-3-2. One, six, five.....four, three, ....two. Wait a second. That makes no sense. 1 is the forward cylinder on the driver's side, so 2 should be the forward cylinder on the passenger side, not 6.    I can't believe it, but I'm looking right at it. Swapped 2 and 6 on the distributor and turned the key over, and...   It fired, coughed and stumbled, smoked, and then settled into a smooth idle. The scanner showed no codes, no lights on the dash, and the throttle was nice and responsive to gentle revs while it warmed up.   It's working!!! IT'S WORKING!!!   I paused for a late dinner, no cold beverage yet. I was determined to do my shakedown run. Did a basic safety and fluids check one more time and then went out and put almost 70 miles on it last night. She's a runner, runs good.   Came home and did a post-trip, post-mortem. The underside is dry *except* for where the last owner RTV'd the snow out of the intersection of the timing cover and oil pan. He said he had replaced the timing cover seal, but, my dude had clearly done it incorrectly and then tried to hold back fate with black RTV. Never works.   Yesterday morning I replaced the broken driver's door mirror. As much as I hate cheap Chinese parts, thank goodness for cheap Chinese parts. I think an entire new power mirror assembly cost me like $30, and it works perfectly. Replacement tail lights (faded, and one was busted) ran me about $12/side. I have a door pin kit ready to go in because the driver's door sags just a little and I want to fix that because there's nothing sadder than a saggy door.   I don't know what's next for this rig. Half of me wants to take some nice photos (there's a park nearby with a HUGE American Flag that always seems to be catching wind) and throw it up on CL/Marketplace for a couple grand and see if it flies. The other half of me... I've got a sweet running S10 Blazer that's been keeping my mind off of whatever I'm going through right now, and it's bringing some joy, and is cheaper than therapy. Maybe I'll keep it around for a little while. However, this is my 5th vehicle, just for me. 4 is really my limit, but they are not junk, so need very little attention. I don't know...there's a point where it's just too much and I don't see owning this truck long term. But I solved its major problem, got it running, so I'm going to stick a feather in my cap for now.   Sometimes we just need to get our hands dirty and fix something in the physical world to gain some satisfaction.
