How To Fix Code P2096 On The Car?

In the simplest of terms, the P2096 fault code indicates the Powertrain Control Module (PCM) has received data from the oxygen sensors in the exhaust system that there is an excess of air and shortage of fuel within the number one cylinder. Although this code is normal still think repairing the car is a better option or to make a temporary solution just follow the below steps of how to fix code p2096.

What Does Code P2096 Mean?

A P2096 code indicates that you’re experiencing an issue with your air-to-fuel ratio. The P2096 code is specifically triggered by a problem with Oxygen Sensor. This is the oxygen sensor that sits downstream from the catalytic converter.

When this sensor indicates that the air-to-fuel ratio in your car is too high, it will return a P2096 code. While your vehicle normally adjusts the air-to-fuel ratio automatically as you drive, this might not always be possible.

In most cases, a P2096 code is the result of too much air in the system or a lack of fuel being released. Either way, this means the air-to-fuel ratio will be too high.

Causes Of Code P2096

There are a variety of root triggers that can cause a P2096 code to appear. Unfortunately, this means that you might have to do a little more troubleshooting to identify the problem.

Below, let’s explore some of the common causes of a P2096 code on your OBD2 scanner:

  • The fuel pressure regulator is not working.
  • Mass airflow sensor is not working or damaged.
  • The fuel filter is clogged.
  • The catalytic converter is clogged.
  • There are leaks in the vacuum or exhaust.
  • The exhaust manifold is cracked or rusting.
  • The oxygen sensor or oxygen sensor circuit is malfunctioning.

How To Fix Code P2096?

When dealing with a P2096 code, you don’t have to panic and immediately go to the repair shop. Instead, you should try a couple of times that might help you get rid of the problem at home. This way, you don’t have to worry about every high and expensive repair cost, especially if you’re going to a dealership.

Below there are the following steps to know how to fix code p2096

1. Use An OBDII Scanner 

The first thing you need to do to get rid of the P2096 code is to check whether the code exists or not. Many drivers might rely on general symptoms and immediately perform common repairs. However, that’s not how it should go. Instead, you need to use a certain specified scanner and get it connected to the vehicle to scan any internal errors.

This scanner is usually referred to as the OBD II scanner. Once you connect the OBDII scanner, you will see on the screen a pop-up showing an error code.

Once you confirm that the P2096 code exists, you can go ahead and try the below steps in the following way.

2. Check For Small Exhaust Leaks 

Over time reviews, small leaks can develop across the chambers. These chambers run beneath the vehicle and end with a tailpipe that you see at the rear part of your vehicle.

A small leak can happen anywhere across these champers and sometimes it can be a little challenging to detect where the leak exactly is happening. Usually, most small leaks happen around the exhaust corners. If that’s the case, you can use exhaust putty and seal out any small leaks that you can visually detect.

In case you are looking for the best results, it recommends that you start with cleaning the leak area and scrubbing it with sandpapers before applying the putty. This way, you get the best results and ensure that the leak is seal completely. It also recommends that you should stir the party enough before applying it to the craft area. As you apply the paste, make sure to press hard to ensure that the material goes through all small leaks and covers them completely.

Do not attempt to start the engine because if you start when the party is not dried enough, the pressure within the exhaust system could blow out the material you just apply. Based on previous experience, you recommend allowing the pace to sit between 6 to 24 hours, depending on the room temperature. Usually, the hotter the temperature, the faster it is for the putty and the paste to dry.

If you don’t want to wait for an extended time, you can always use a hairdryer to help dry out the paste faster without needing to wait up to 24 hours.

3. Check For Large Exhaust Leaks 

Larger exhaust leaks usually occur around the exhaust pipes that are made of rolled steel. Therefore, inspect the exhaust pipes for any signs of major leaks. Once you detect one, you can use sandpaper to clean and prepare the area.

Larger leaks cannot be fixed by simply using a putty; You need to purchase what’s referred to as the heat wrap. This heat trap should be activated by soaking it in warm water. Once the heat wrap is activated, you can roll it around the large leak. Allow the engine to run for up to 30 minutes to get the best results.

4. Inspect The Oxygen Sensor 

Another comment problem that might cause the P2096 is a faulty oxygen sensor. Inspect the oxygen sensor on bank one for any signs of damages.

In case you find that the oxygen sensor damage, you need to replace it immediately to eliminate the problem.

5. Clear the P2096 code 

Once resolving the issue successfully, you need to go ahead to get out. Remember that any error code associated with the check engine light does not clear itself. And it’s your job to connect your OBDII scanner to the vehicle’s computer and ask it to clear inactive codes.

Once you clear the codes, we always recommend that you perform a second check to see whether the code was cleared completely. If that was not the case, it indicates that you either did not follow the process correctly or the problem is linked to something else.

6. Visit A Repair Shop 

If none of the mentioned steps helped you resolve the P2096 code, the only solution is to take your vehicle to the nearest repair shop. At the repair shop, professional mechanics should implement manufacturer tests associate with certain models and makes. This way, the mechanic should be able to detect the actual root of the problem.

Can I drive my car with a P2096 code?

If your vehicle registration to have a P2096 code, the problem is not life-threatening, which means that you can still drive your car. However, ignoring issues with the air-fuel mixture can introduce damages to the other exhaust system components.

Therefore, even if fixing the P2096 code will not cost you a lot, repair costs can pile up by ignoring the problem for an extended time, which might be out of your expected budget.

In case to make a budget-friendly repair follow the above following steps of how to fix code p2096.


Whenever diagnosing the cause of the P2096 OBD-II trouble code, bear in mind that the process takes time and may require multiple tests to identify the specific cause of a too lean fuel mixture. The investment of this extra time and labor upfront helps to ensure that not only the root cause is detected and fixed but also that any other components that have been adversely affected are also repaired or replaced.
