P06dd Jeep Wrangler – Error Code Explained!

Are you familiar with P06dd Jeep Wrangler error code?

The Jeep Wrangler is one of the world-leading off-road vehicles. If you are one of the lucky owners of this beast, we are sure you like to push it to its limits. And we don’t blame you since Jeep Wrangler is made to be persistent.

However, it can get scary if your dashboard warning light turns on. In this text, we will explain the possible reasons a P06dd code is showing on your Jeep. Also, we will guide you through some general dashboard light rules.

Warning Lights on a Dashboard


You can think about signs on a dashboard as a language your car speaks to you. Sometimes, it will only notify you to close the door properly. Other times can be a lifesaver.

Even though some of those dashboard signs can turn on and you can still keep driving – it is best to get it checked as soon as possible. Follow this logic: over time, a small issue can become bigger – so solve it on time.


And what are the types of signs cars can give you? Firstly, some icons are unified for all car types. So, for example, the well-known check engine light notifies a driver there is an issue.

Check engine light

In fact, your Jeep Wrangler most likely first showed you the check engine light. Then, after a while, you got the P06dd code.

Alphanumeric codes (DTC)

As you may already know, we have alphanumeric codes for the other type of car dashboard signs. They go by the name DTC: Diagnostic Trouble Codes. DTC identifies what exactly the issue with your car is. So, of course, P06dd is a diagnostic trouble code. [1]

So, what does P06DD Jeep Wrangler Code Mean?

Before we get to that, it is important to understand that all DTC codes consist of five characters. Each character provides you with a different piece of information about the vehicle’s issue.

P in the P06DD

Normally, the first character is a letter. It shows which part of the car has a problem. Here are the meanings:

  • B – Body.
  • C – Chassis.
  • P – Power Train.
  • U – Network.

Therefore, P stands for engine, fuel system, or associated accessories.

0 in the P06DD

The second character is always a digit, either 0 or 1.

Zero shows you that the issue is the standardized SAE code. SAE (formerly known as the Society of Automotive Engineers) is a United States-based, globally active professional association and standards-developing organization for engineering professionals in various industries. Principal emphasis is placed on global transport industries such as aerospace, automotive, and commercial vehicles. (1)

One tells us that the code is vehicle manufacturer-specific, in this case, Jeep only.

Nonetheless, in your P06DD code, we can see that it is a standardized issue.

6 in the P06DD

The third figure is again a digit, going from 1 to 8. Numbers are referring to some of these problems:

1 and 2 – fuel or air metering system

3 – ignition system

4 – emissions system

5 – idle control system and vehicle speed controls

6 – computer output circuit

7 and 8 – transmission-related issues.

DD in the P06DD

The last two characters (DD) are normally numbers between 0 and 99 or letters, showing the specific fault index.

Finally, what is the possible cause of your P06DD Jeep Wrangler Code?

It can be some of the issues listed below:

  • Your engine oil is low or dirty.
  • Your oil pressure sensor is improper.
  • Your oil pressure sensor harness is open or shorted.
  • Your oil pressure sensor circuit has poor electrical components.

Examine all the connectors and harnesses carefully to distinguish and solve your particular issue. If you see some damaged, broken, or corroded parts – there is your problem.

Can I Drive with Code P06DD?


No matter why your P06DD is showing, driving is not recommended when it appears. Instead, it would be best to contact the closest auto repair shop so they can solve the issue right away.

Can I Solve the Issue Myself?

If you are patient enough and have the proper equipment and knowledge, you can fix the DTC Code on your Jeep Wrangler.

To get the right diagnosis for your trouble code, thoroughly inspect all the parts connected to the related issue. In this case, you will need to check the oil pressure supply.

Anyway, a brief explanation of the steps you could take would be:

  1. Check whether the DTC Code is right and if any additional code is showing.
  2. For this, you will need an OBD scanner – a useful tool that can help you read DTC codes. In addition, you can read the owner’s manual to find the OBD port location on your Jeep Wrangler. However, the port is most likely located above the pedals on the left side.
  3. When you connect the scanner, you should check if P06DD is the only thing showing. If there is another code, you will need to interpret it and deal with it.
  4. Clear the code and turn on the Jeep to double-check if the P06DD appears again.
  5. If your code keeps showing, you will need to check the engine oil and notice if there are any irregularities. Also, see if your Jeep Wrangler has oil sludge, if engine oil is dirty or if there is some aeration.
  6. You must inspect the oil pump to see if everything is okay with your oil and filter. Sometimes, you will need to replace the entire oil pump assembly since it does not have sub-parts you can buy and restore.
