What does code P2E89 mean?

Q: What does code P2E89 mean?

Proximity Detection Circuit B Low. P2E89 is a generic OBD-II code that indicates the powertrain control module has detected a low voltage condition on the proximity detection circuit B, which is part of an advanced driver assistance system such as a blind spot monitor or parking assist. The computer monitors the circuit for expected voltage and sets this code when the signal falls below the calibrated threshold, often due to a wiring fault, sensor issue, or module problem.
