Q: What does code P2E88 mean?

Proximity Detection Circuit B Range/Performance. P2E88 indicates that the powertrain control module has detected an out-of-range or performance fault in the proximity detection circuit B, which is typically part of an advanced driver assistance system that senses nearby objects. The computer compares the circuit's signal against expected values and flags this code when the voltage, current, or response time falls outside the manufacturer's specified window.
