What does code P2E8B mean?

Q: What does code P2E8B mean?

Proximity Detection Circuit B Intermittent/Erratic. P2E8B indicates that the powertrain control module has detected an intermittent or erratic signal on the proximity detection circuit B, which is typically part of an advanced driver assistance system such as blind spot monitoring or rear cross-traffic alert. The computer sets this code when the circuit's voltage or resistance fluctuates outside expected limits for brief, unpredictable periods rather than failing completely.
