2013 Ford Escape P0234 Code: Is It a Sensor Issue or Real Turbo Over-Boost Risk?

I recently purchased a used 2013 Ford Escape about a week ago, and yesterday the check engine light came on. I took it to AutoZone for a diagnostic, and they reported a P0234 code — indicating turbo or supercharger over-boost condition. This has me very concerned because I’ve read that over-boosting could potentially damage the engine, even leading to blown gaskets. My vehicle doesn’t show any signs of surging, RPMs remain stable during driving and idle, and the engine runs smoothly with no noticeable overheating or shifting issues. I’ve monitored my instant fuel economy throughout the ride home, and nothing seemed out of the ordinary. Given this, I’m wondering: what is the likelihood that this issue stems from a faulty sensor rather than an actual over-boost condition? I’m considering replacing the sensor myself, but I don’t want to continue driving it if there’s a real risk of engine damage. If the turbo were truly malfunctioning, I would expect symptoms like sudden RPM spikes, overheating, or surging — none of which I’ve experienced. Additionally, the AutoZone technician mentioned that the P0234 code has been cleared three times previously. Does this make a difference in diagnosing the root cause? Any insights or advice from experienced users would be greatly appreciated! Thanks!
