If you’ve been driving for a while, you’ve probably had to deal with a check engine light. If it’s accompanied by the codes P1133 and P1153, here’s what you need to know. These two codes indicate that there is a problem with the air/fuel mixture in your vehicle.
The first step in troubleshooting this issue is to check your oxygen sensor.
Chevy P1133 Oxygen Sensor (O2) Diagnosis and Replacement
- Check the engine’s air filter and replace it if necessary
- A dirty air filter can restrict airflow to the engine, causing the P1133 and P1153 codes
- Inspect the air intake duct for any cracks or holes
- A damaged duct can leak unmetered air into the engine, triggering the codes
- Clean or replace the mass airflow sensor if necessary
- Over time, dirt and debris can build up on the sensor, causing it to malfunction and throw off readings
- This can cause both P1133 and P1153 codes
- Check all of the vacuum hoses going to and from the engine for any leaks or damage
- A leaking hose can introduce unmetered air into the system, leading to false readings from various sensors and eventually triggering a check engine light with one of these codes stored in memory
How to Fix Code P1153
If your check engine light is on and you’re getting a Code P1153, it means that your oxygen sensor isn’t working correctly. Here’s how to fix it.
1. Check the wiring to the oxygen sensor.
If there are any loose, frayed, or broken wires, replace them.
2. Inspect the oxygen sensor itself for damage. If it looks damaged, replace it.
3. Check the air filter. A clogged air filter can cause this code to be thrown. Replace the air filter if necessary.
4. Check for vacuum leaks around the intake manifold and other engine hoses/components. A vacuum leak can cause this code to be thrown as well.
P1153 Manufacturer Control
If your check engine light is on, you may have a P1153 manufacturer control fault. This code is related to the emissions system and indicates that there is a problem with the manufacturer’s control of the system. The most common cause of this code is a faulty oxygen sensor, but it can also be caused by a problem with the catalytic converter or exhaust gas recirculation (EGR) system.
If you have this code, it’s important to get it diagnosed and repaired as soon as possible to avoid damaging your engine.
P1133 Vacuum Leak
If your vehicle is displaying the P1133 code, it means that there is a vacuum leak in the system. The most common cause of this problem is a leaking gasket or seal. If you have a vacuum leak, it can cause your engine to run lean and may eventually lead to engine damage.
It’s important to fix this problem as soon as possible. Here are some tips on how to troubleshoot and fix a vacuum leak:
1. Check all of the gaskets and seals in your engine for leaks.
Replace any that are damaged or worn out.
2. Inspect all of the hoses and pipes in your vacuum system for cracks or leaks. Replace any that are damaged or leaking.
3. Make sure all of the clamps in your vacuum system are tight and secure. Loose clamps can cause leaks.
P1153 Chevy Code
If your Chevy is displaying the P1153 code, it means that the powertrain control module (PCM) has detected a problem with the bank 2 sensor 1 oxygen sensor signal. The PCM uses data from the oxygen sensors to help monitor and adjust engine combustion. When there’s an issue with the signal from this particular sensor, it can cause problems with engine performance.
There are a few things that can cause the P1153 code to trigger:
-A problem with the oxygen sensor itself
-An issue with the wiring or connectors for the oxygen sensor
-A problem with the PCM
If you’re getting this code, it’s important to have your vehicle checked out by a mechanic as soon as possible. They’ll be able to diagnose the problem and let you know what needs to be done to fix it.
In some cases, simply replacing the faulty oxygen sensor will take care of the issue. However, if there’s another underlying problem, such as an issue with the PCM, it will need to be addressed as well before your Chevy will run properly again.
P1153 Code
If your car is displaying a P1153 code, it means that the powertrain control module (PCM) has detected a problem with the air/fuel mixture sensor. This sensor is responsible for monitoring the air-to-fuel ratio in your engine, and when it detects an imbalance, it will trigger the P1153 code.
There are a few potential causes of this problem, including a faulty air/fuel mixture sensor, a blockage in the exhaust system, or a problem with the PCM itself.
In some cases, simply replacing the oxygen sensor can fix the issue. However, if there is something more serious going on, such as a clogged catalytic converter, then more extensive repairs will be necessary.
If your car is displaying a P1153 code, take it to a mechanic as soon as possible so they can diagnose and fix the problem before any further damage is done to your engine.
P1153 Code Chevy Suburban
If your Chevy Suburban is displaying the P1153 code, it means that there is an issue with the readings from the front oxygen sensor. This code is associated with a lean condition in the engine, which can be caused by a variety of things. The most common cause of this code is simply a dirty or faulty oxygen sensor.
If you suspect that this may be the case, you can try cleaning or replacing the sensor to see if that clears up the problem.
Other potential causes of this code include vacuum leaks, fuel injector issues, or problems with the air intake system. If you have checked for and ruled out these other potential causes, then it’s likely that you do indeed have a faulty oxygen sensor.
In this case, you’ll need to replace the sensor in order to clear the code and get your engine running correctly again.
P1153 Code Chevy Tahoe
If your Chevy Tahoe is displaying the P1153 code, it means that there’s an issue with the vehicle’s air/fuel mixture. This can be caused by a number of different factors, including a dirty air filter, a faulty oxygen sensor, or a problem with the fuel injectors.
If you’re seeing the P1153 code, it’s important to have your Tahoe checked out by a qualified mechanic as soon as possible.
They’ll be able to diagnose the problem and get your SUV back on the road in no time.
P1133 Code
P1133 is a code that can be stored in the computer of a vehicle when there’s an issue with the air/fuel sensor. The purpose of this sensor is to monitor the oxygen levels in the exhaust and make sure they’re at proper levels. If the computer detects that something is wrong with this sensor, it’ll throw the P1133 code.
In most cases, this simply means that the sensor needs to be replaced.

What is P1133 And P1153?
A P1133 code is a diagnostic trouble code (DTC) for a problem with the air/fuel ratio sensor in bank 1, sensor 1. This sensor is also known as the front oxygen sensor or upstream oxygen sensor. The job of this sensor is to measure the amount of oxygen in the exhaust gas and send this information to the powertrain control module (PCM).
The PCM uses this information, along with other inputs, to calculate the correct air/fuel mixture for optimal engine performance and emissions.
A P1153 code is a DTC for a problem with the air/fuel ratio sensor in bank 2, sensor 1. This is also known as the rear oxygen sensor or downstream oxygen sensor.
The job of this sensors is similar to that of the front O2 sensors – it measures the amount of oxygen in the exhaust gas and sends this information to the PCM. The PCM uses this information along with other inputs to calculate the correct air/fuel mixture for optimal engine performance and emissions.
