When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be indicating a fault code of p1133. This code specifically relates to the oxygen sensor in your vehicle.

The oxygen sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases.

It helps the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. A p1133 fault code suggests that there is a problem with the oxygen sensor located in the bank 1 sensor 1 position. This means that the sensor in question is located before the catalytic converter and on the side of the engine with cylinder 1.

The fault code indicates that the oxygen sensor is not responding as expected or is providing inaccurate readings. This can lead to issues with fuel efficiency, emissions, and overall engine performance. If you encounter a p1133 fault code, it is important to address it promptly.

Ignoring the issue can result in decreased fuel economy, increased emissions, and potential damage to other engine components.

It is recommended to have a qualified mechanic diagnose and repair the problem to ensure proper functioning of the oxygen sensor and optimal engine performance.

How can a faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 cause the automobile fault code p1133?

A faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 can cause the automobile fault code p1133. This can result in symptoms such as poor fuel efficiency and engine performance.
