To fix codes p1133 and p1153, replace the faulty oxygen sensor. These codes indicate a problem with the oxygen sensor’s circuit in bank 1 and bank 2, respectively.

The oxygen sensor plays a critical role in a vehicle’s emission control system, helping to measure the level of oxygen in the exhaust gases. However, a malfunctioning oxygen sensor can lead to decreased fuel efficiency and increased emissions. If your vehicle has triggered codes p1133 and p1153, it’s likely that the oxygen sensors in bank 1 and bank 2, respectively, are not functioning correctly. While other issues can cause these codes, replacing the oxygen sensors is generally the first step in addressing the problem. Here, we’ll explore some additional information about these codes and what you can do if your vehicle triggers them.

Understanding Code P1133 And P1153


Code p1133 and p1153 are related to the oxygen sensor in a vehicle’s engine. P1133 is specifically related to the bank 1 sensor 1 oxygen sensor, while p1153 is related to the bank 2 sensor 1 oxygen sensor. Both codes indicate that the oxygen sensor is not functioning properly, which can affect the vehicle’s performance.

Symptoms of these codes include decreased fuel efficiency, engine misfires, and difficulty starting the engine. To fix these codes, the oxygen sensor may need to be replaced. It’s important to address these codes promptly, as they can cause damage to other parts of the engine if left unresolved.

Causes Of Code P1133 And P1153


Code p1133 and p1153 are usually caused by faulty oxygen sensors. These sensors play a significant role in ensuring the vehicle’s engine runs efficiently. A failed air/fuel ratio sensor can also trigger these codes. The sensor acts as a feedback mechanism for the engine control unit (ecu) to optimize the air/fuel mixture.

Malfunctioning mass airflow sensors can also cause these codes. This sensor is responsible for measuring the air coming into the engine. When the sensor gets clogged or fails, it can affect the engine’s performance. It’s crucial to diagnose and repair these codes promptly to avoid further damage to the engine.
