🔧 The Sensor That Brought My Engine Back to Life 🔧
I was stranded—again. My 2011 Silverado 2500HD had been stalling, refusing to start, and throwing crankshaft position sensor codes. I’d tried aftermarket parts before, but they never lasted. Then I found the ACDelco GM Original Equipment 12703627 Crankshaft Position Sensor. Installation was straightforward. I swapped out the old sensor, plugged in the new one, and hoped for the best. The difference was immediate. My truck started on the first turn, idled smoothly, and ran like it used to. No more stalling. No more hesitation. Just reliable performance. I’ve learned the hard way that cutting corners with cheap parts doesn’t pay off. This sensor is the real deal—OEM quality that restored my engine's timing and fuel injection synchronization. If you're dealing with crankshaft sensor issues, this is the one to trust. 💪

The original lasted 155k, so I got another AC Delco. I got a P0335 code so I replaced this sensor. The car seems to run fine without doing the relearn process. I will do the relearn when I can borrow a scanner.
