Definition of Code P2096
P2096 – Post Catalyst Fuel Trim System Too Lean Bank 1
What is the P2096 Code?
A trouble code P2096 indicates that your vehicle's catalytic converter is emitting a mixture of lean fuel and air. The oxygen sensor reads this mixture and transfers it to the powertrain controller module (PCM). It’s a generic code found with most major automotive brands.
The Bank 1 oxygen sensor is located on the side of the V6 and V8 motors. It won’t have the same meaning with straight cylinder engines. The downstream sensor monitors the oxygen coming from the converter while the upstream sensor detects the engine's combustion.
When the oxygen is high in the mixture, it’s referred to as running lean, while a lower concentration of oxygen is known as running rich because of how much fuel is present.

P2096 Trouble code symptoms
As a result, the Check Engine Light will be illuminated. The unbalanced air-to fuel ratio can cause performance issues.
These are the most common symptoms that have been reported using this code.
What is the P2096 code?
There’s no straightforward answer to what causes the P2096 trouble code to set. That’s why it’s important to follow our diagnostic procedures, laid out later in the article.
These are just a few examples of top causes.
What is the P2096 Code and How Serious?
Medium – You shouldn’t have trouble driving the vehicle home once the code sets. You should be able drive the vehicle home, despite possible performance problems.
You should not continue to drive the car if it isn't fixed immediately. If it’s not fixed soon, you could face higher repair bills in the future.
How can you fix the P2096 code?
You will be able to identify the exact problem if you follow these steps. These are the best fixes to get you on your way again.
- Repair fuel system
- Replace spark plugs
- Fix vacuum leak
- Fix exhaust leak
- Change catalytic converter
- Replace oxygen sensor
- Rewire or repair damaged wires
- Replace mass airflow sensor
- Replace/update PCM
Common mistakes in diagnosing P2096
It could happen, depending on which vehicle you have. It’s wise to check service bulletins from the automaker before getting started.
Many Chrysler and Jeep cars can sometimes be affected by this code. The repair will usually require you to clean the wiring and reconnect it.
How to diagnose P2096 Trouble Code
You don’t have to be a professional mechanic to troubleshoot the P2096 code. Instead, you just need to be able to follow the instructions in your car’s service manual and our general guidelines.
These steps will get you started.
- You should read all the codes. It could be helpful to identify the source of the problem if there are more than one.
- Check the wires and connections. You can repair anything that is obvious.
- Make sure to inspect the spark plugs. If they become fouled, replace them.
- Test for a vacuum leak, as per the car’s service manual.
- You should test for an exhaust leak.
- Analyze the fuel delivery systems. Use a scanner or mechanical gauge to determine the fuel pressure.
- With an advanced scan tool, you can also monitor the oxygen sensor performance to ensure it’s accurate.
If these steps don’t show you where the problem is, it’s best to consult with a professional.
The estimated repair cost of P2096
Once you figure out the problem, it’s time to budget for the repair. Here are the approximate prices for parts and labor if you have to hire a mechanic.
- Repair fuel system – $50-$750
- Replace spark plugs – $50-$350
- Repair vacuum leak – $150-$850
- Repair exhaust leak – $75-$650
- Replace catalytic converter – $900-$2,500
