P0134

The BMW 3 Series F30/F31 (2012-2019) has triggered a P0134 trouble code, indicating a malfunction in the oxygen sensor circuit, particularly related to the upstream (pre-catalytic converter) oxygen sensor.

A P0134 code indicates that the Engine Control Module (ECM) has detected a problem with the upstream oxygen sensor (O2 sensor) performance in a BMW 3 Series F30/F31 (2012-2019).

The P0134 code indicates a malfunction related to the upstream oxygen sensor (O2 sensor) on a BMW 3 Series F30/F31 (2012-2019). This code typically signifies a slow response time or a no activity detected from the oxygen sensor.

The P0134 code indicates a problem with the oxygen sensor circuit in the 2019-2024 BMW 3 Series G20/G21, specifically related to the upstream oxygen sensor (Bank 1, Sensor 1), which is not receiving a valid signal.
