Will a bad camshaft sensor cause Chevy trail blazer to shut off?

Yes, a bad camshaft position sensor (CMP sensor) can definitely cause a Chevy Trailblazer to shut off, especially while driving. The CMP sensor tells the engine's computer (PCM) where the camshaft is in its rotation. If the PCM doesn't receive a signal or receives a faulty signal, it may shut the engine down to prevent damage. This is a common cause of no-start or stalling issues.
