Definition of Code P0310
P0310 – Cylinder #10 Misfire Detected
What does the P0310 code mean?
P0310 DTC means that there’s an engine misfire in cylinder 10. Powertrain Control Modules (PCMs) alert the engine when a misfire is detected in the 10th car motor cylinder. It’s a generic code, applying to all OBD-II equipped models.
The P0310 trouble codes can be considered to be generic. However, it could vary depending on what make and model of vehicle you have. You might also notice the P0300 code if there are several misfires. This could be combined with any other codes that indicate problems with other parts of your vehicle.
Trouble Code P0310 Symptoms
Performance issues can be noticed if an engine cylinder fails to fire. The Check Engine Light will turn on when the code has been set. This alerts you to the issue.
Here are some of the top symptoms you’ll notice with the P0310 DTC.
What causes the P0310 code?
There are many reasons why your car's engine may be stalling. In some cases, the issues could stem from the ignition system, but it’s also possible that something has failed with the fuel system.
These are the top causes of P0310 trouble codes.
Is the P0310 Code Really Serious?
Very severe – The P0310 DTC is considered one that should be taken seriously. An engine misfire could make driving dangerous. This is especially true if your car stalls in the middle. You could be in danger if the engine suddenly stops.
It’s important to have the P0310 trouble code examined as soon as possible. Other engine problems can be caused by misfiring engines, which will increase the cost of repairs. You might also need to hire a tow truck if your car is unable to start.
Which Repairs can Fix the P0310 Cod?
It is essential to perform an extensive diagnosis before you begin any repair. Otherwise, you could spend unnecessary money on parts that aren’t needed.
Here are some possible solutions based on the most common failures.
- Replace spark plug
- Replacing the coils/wires
- Install a brand new fuel injector
- Fix leaking valve
- Repair vacuum leak
- Change the piston ring
- Repair leaking head gasket
- Replace computer module
Common errors in P0310 diagnosis
The most common cause of misfires is the coil pack, spark plugs, coils, wires and ignition coils. However, you should never assume that’s the problem without first performing the diagnostic steps we outline. Before replacing the coil, you should first inspect all wires and plugs.
You can then move on to parts that are not working properly. A compression test is also recommended. Additionally, if there are any other trouble codes present, these might help you narrow down what’s going on.
How do you diagnose the P0310 trouble code?
Professional mechanics should follow a plan for diagnosing P0310 codes. Gathering the code from the scanner is just the first step of figuring out what’s wrong. The right steps will give you the answer.
These are some of the more common steps to diagnose the P0310 DTC.
- Collect the trouble codes with your OBD-II scanner and use freeze frame data to see what’s going on. Use the OBD-II scanner to collect trouble codes and then use freeze frame data to troubleshoot based on any additional codes.
- Set the code back to default.
- To find out which codes are back, test drive the car.
- To determine if the spark plug or ignition coil is worn, inspect the coil pack or wire on cylinder 10. Replace if necessary. You can try to move over the spark plug and ignition coil to another cylinder to see if you get a trouble code on the other cylinder instead – if so replace the faulty spark plugs and ignition coil.
- Vacuum leaks can be found in the intake.
- If this isn’t the problem or the code doesn’t go away, you will need to inspect the fuel injectors.
- You might need to inspect the distributor cap as well as the ignition cables if you own an older vehicle.
- A compression test on cylinder 10 is required beyond this.
- If necessary, check the timing of the camshaft and examine the shaft or timing belt.
- If you can't find anything else with diagnostics, it is possible that the PCM needs to be replaced. However, with this problem, you’ll likely see other false codes or problems.
The estimated cost of repair
Depending on what’s causing the problem, you are looking at a varying amount of repair costs. You will pay less to repair some problems than others. Here are some of the most popular repairs, along with the average labor and parts costs.
- Replace spark plug – $40-$350
- Replace ignition coils/wires – $75-$400
- Install a new fuel injector – $200-$500
- Fix leaking valve – $500-$2,500
- Replace piston ring – $1,000-$5,000
- Repair leaking head gasket – $1,500-$3,000
- Replace computer module – $750-$3,500
The P0310 Code: Mechanics Tips
It is possible to replace the plug if the problem with the cylinder 10 sparkplug causes the code p0310. However, it’s always a better idea to replace all of the plugs at the same time. The first one will fail and then the other ones will likely follow. You can also replace the spark plugs quickly and easily to keep on top of the recommended maintenance.
It is also important to ensure the spark plugs are properly gapped. It is possible to have a misfire if the gap between spark plugs and metal is not right. Use a spark plug gap tool to ensure the space matches the manufacturer’s specs.

Most Frequently Asked Questions
Are you able to safely drive with a code P0310?
A P0310 error code is dangerous and it should not be used to cause unsafe driving conditions. A P0310 code is an indication that the engine on cylinder 10 is not firing properly. You should not continue to misfire the cylinder. This could damage your internal engine components or catalytic converter, and can lead to costly repairs.
Is it worth fixing the P0310?
First, diagnose the problem to determine what it costs to repair the P0310 code. If the cause of your P0310 error is a simple spark plug or ignition coil problem, you could be charged between $50-150. It is possible that the problem could be caused by low compression. In rare instances, you may have to spend more than $5000 in order to repair it.
What is the best way to fix error P0310
You must first diagnose the problem and fix it. The most common reason for a P0310 error is a bad spark plug or ignition coil. This is where to start your diagnosis.
What is the meaning of P0310?
If the P0310 code is displayed, it means that engine control module detected misfires in cylinder #10. It needs your attention. A failing spark, low fuel compression or problems with fuel delivery can all cause misfires in car engines.
Is there a reason for the P0310 error code?
Many issues can lead to engine misfires in cylinder 10, which could result in a code P0310. Faulty spark plugs or ignition coils are the main causes of the P0310 code. Two other causes of a P0310 trouble code are vacuum leaks and a defective fuel injector.
