What does code P2E87 mean?

Q: What does code P2E87 mean?

Proximity Detection Circuit B. P2E87 indicates that the powertrain control module has detected a fault in the proximity detection circuit B, which is part of an advanced driver assistance system such as a blind spot monitor or parking assist. The circuit typically uses ultrasonic or radar sensors to detect objects near the vehicle, and the code sets when the module sees an abnormal voltage, resistance, or signal pattern on the 'B' circuit.
