Possible Causes of Ford Code P1131 P1151

1. Oxygen Sensor Malfunction

An oxygen sensor malfunction is a common cause of Ford code P1131 and P1151. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases and providing feedback to the engine control module (ECM). When the oxygen sensor fails or becomes contaminated, it can lead to inaccurate readings and trigger these codes.

2. Vacuum Leak

A vacuum leak in the intake manifold or associated hoses can also cause codes P1131 and P1151 to appear. A vacuum leak allows unmetered air to enter the engine, disrupting the air/fuel mixture and causing the engine to run lean. This can result in the ECM detecting a problem with the oxygen sensor readings.

3. Faulty Fuel Injector

If one or more fuel injectors are not functioning properly, it can affect the air/fuel mixture and trigger codes P1131 and P1151. A faulty fuel injector may be delivering too much or too little fuel, causing the engine to run lean or rich. This can lead to inaccurate oxygen sensor readings.

4. Intake Manifold Gasket Leak

A leak in the intake manifold gasket can introduce excess air into the engine, leading to a lean condition and triggering the P1131 and P1151 codes. Over time, the intake manifold gasket can deteriorate, causing gaps or cracks that allow air to bypass the throttle body and disrupt the air/fuel mixture.
