P0134

The P0134 code indicates a slow response from the oxygen sensor circuit in the Ford F-150, specifically related to the upstream (pre-catalytic converter) oxygen sensor, which can lead to poor fuel economy and increased emissions.

The P0134 code indicates a malfunction related to the upstream oxygen sensor circuit for the Ford F-150 Fourteenth Generation (2021-present). This code typically refers to the sensor's performance being outside the expected range or the sensor not providing a signal.

The P0134 code indicates a problem with the upstream oxygen sensor (O2 sensor) on a Ford F-150 from the Fourteenth Generation (2021-present), specifically signifying that the sensor is reporting a signal that is too low or not fluctuating as expected.
