Code P1132 2001 Ford F150 Description

The diagnostic trouble code P1132 for a 2001 Ford F150 indicates a lack of response from the upstream heated oxygen sensor (HO2S) on bank 1, which is typically the side of the engine where cylinder 1 is located. The upstream HO2S is responsible for measuring the oxygen content in the exhaust gases before they enter the catalytic converter. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture to achieve optimal combustion efficiency.
