P2023 is meant for a bank 2 flap position signal that briefly drops out or jumps without staying out of range long enough for P2021 or P2022. No manufacturer documents this code publicly; Ford's V-engine summaries stop at low, high and over-travel for bank 2, and Volkswagen's Touareg tables skip it. The closest published analogue is P2018 on bank 1, which Mitsubishi lists for the PR25DD-engined Outlander as a two-trip fault with warning lamp. CARB's rules for comprehensive components require circuit faults of emission-related inputs such as variable runner systems to be detected, so a calibration may use P2023 for unstable feedback. In practice it points to a loose connector, a chafed loom on the hot side of the engine or a worn sensor.

Likely causes

Bank 2 sensor plug with loose or corroded contacts
Harness rubbing through near exhaust or valve cover
Worn bank 2 position sensor giving dropouts

Symptoms

  • Warning lamp appears now and then
  • Usually no change in how the engine drives
