Details of the Ford p1152 OBD Code
Ford code P1152 relates to a lack of switching for the upstream oxygen sensor.
Ford OBD code P1152 means the Heated Oxygen Sensor (HO2S) 1, Bank 2, is indicating a lean condition.
This code is triggered by the Engine Control Module (ECM) based on the signal received from the HO2S sensor located in the exhaust system.
The ECM monitors the oxygen content in the exhaust gases to adjust the airfuel mixture for optimal combustion.
A lean condition indicates there is too much oxygen in the exhaust, which can be caused by issues like a vacuum leak, fuel delivery problems, or a faulty oxygen sensor.
