Enhanced O2 for Subaru
This bulletin announces availability of new oxygen sensors for 2020-2-24 Subaru Legacy and Outback 2.5L, 2017-2024 Impreza and Crosstrek, 2019-2023 Forester and 2022-2023 BRZ vehicles. The new oxygen sensors address the following DTCs detected in the ECM:
P0137 (O2 sensor circuit low voltage bank 1 sensor 2)
P0138 (O2 sensor circuit high voltage bank 1 sensor 2)
P0140 (O2 sensor circuit no activity detected bank 1 sensor 2)
P0141 (O2 sensor heater circuit bank 1 sensor 2)
The new O2 sensors have an optimized coating to help prevent cracking within the internal surfaces, reducing any possibility of short/open circuits.
