- Check the engine light to see if it is on. If it is, then there is a problem with the engine and you should take it to a mechanic.
- If the engine light is not on, then you can try to fix the code yourself.
- First, check the air filter to see if it needs to be replaced.
- Next, check the oxygen sensor to see if it needs to be replaced.
- Finally, check the fuel injectors to see if they need to be cleaned or replaced.

Chevy P1133 Oxygen Sensor (O2) Diagnosis and Replacement
What is P1133 and P1153?
The P1133 and P1153 codes are diagnostic trouble codes (DTCs) for a heated oxygen sensor (HO2S) in the front or rear of the vehicle. The HO2S monitors the oxygen level in the exhaust gases and sends a signal to the engine control module (ECM). The ECM uses this information to adjust the fuel mixture. If the oxygen level is too high or too low, the ECM will set a code and turn on the check engine light.
How do I fix my P1133 code?
The P1133 code is a generic code that indicates the engine control module (ECM) has detected a slow response from the oxygen sensor heater element. The most common cause of this code is a faulty oxygen sensor, but it can also be caused by a faulty ECM or oxygen sensor wiring. To properly diagnose and repair this code, a technician will need to use a diagnostic scanner to read the ECM data and check for any other codes that may be present.
What can cause code P1133?
There are a few things that can cause code P1133 to trigger. The most common cause is a faulty oxygen sensor, but it can also be caused by a problem with the air/fuel mixture, an exhaust leak, or a problem with the engine’s computer.
What does engine code P1153 mean?
The P1153 code is a generic powertrain code that indicates the engine control module (ECM) has detected a bank 2 sensor 1 oxygen sensor signal that isleaner than expected. The lean condition may be caused by a vacuum leak, low fuel pressure, or a faulty oxygen sensor.
What is the most likely cause of code P1133?
Code P1133 indicates an issue with the oxygen sensor heater control circuit. The most likely cause of this code is a faulty oxygen sensor, but it could also be caused by a problem with the oxygen sensor heater control relay, the oxygen sensor heater control circuit fuse, or the wiring in the oxygen sensor heater control circuit.
What are the common symptoms of code P1133?
There are several common symptoms associated with the P1133 code. These include the engine light turning on, the engine running roughly, and the vehicle stalling. In some cases, the vehicle may also experience reduced fuel economy.
How can I fix code P1133?
There is not a one-size-fits-all answer to this question, as the code P1133 may be caused by a variety of different issues. However, some possible fixes for this code include repairing or replacing the relevant sensor, testing and cleaning the relevant electrical connection, or checking for and repairing any leaks in the vehicle’s fuel system.
What is the severity of code P1133?
This code is a manufacturer’s specific code, and it indicates a problem with the oxygen sensor bank 1, sensor 1. The code is triggered when the oxygen sensor bank 1, sensor 1 is not switching correctly between the lean and rich states. The severity of this code will vary depending on the make and model of the vehicle, but it can typically be classified as a mild to moderate issue. In most cases, the only symptom of this code will be a check engine light. However, if the problem is left unchecked, it could lead to decreased fuel economy and increased emissions.
What are the consequences of code P1133?
A code P1133 may indicate that the oxygen sensor in your vehicle is not functioning correctly. This can lead to increased emissions, decreased fuel efficiency, and potential engine damage.
