How to troubleshoot & Fix P06dd Jeep Wrangler DTC Code? [Top 4 Fixes]

When the DTC code P06dd is detected on your Jeep Wrangler, it mainly refers to an engine oil pressure sensor issue. The problem affects the oil pump to some extent in the longer run.

No need to be worried, in this article we will cover the ins and outs of the P06dd in the Jeep Wrangler. So, stay tuned with us right through this blog.

What does the P06DD Jeep Wrangler code mean?

It is a DTC trouble code, which mainly implies that the engine oil pressure control circuit is stuck off. The PCM gets a signal from the oil pressure sensor about the oil pressure.

But when it gets the signal that pressure is low and the dual-stage oil pump is affected, the P06DD code is detected in the Jeep Wrangler. We have added a breakdown of the code below to help you understand better:

  • P – Powertrain, the system that drives the vehicle functioning forward
  • 0 – A number as per the SAE standard
  • 6 – Computer output circuit (Dual-Stage pump oil pressure stuck low)
  • DD – Specific Fault Index (Here, the engine oil pressure control circuit is stuck off)

P06DD Code: What causes low engine oil pressure on the Jeep Wrangler?

Several reasons might contribute to detecting the P06DD code on your Jeep Wrangler. When you frequently notice low engine power, noise, and too much vibration from the engine, the P06DD is likely to show up.

We’ll discuss some primary reasons below that affect the dual-stage pump and cause low oil pressure. Those are listed below:

  • Malfunctioning oil pressure sensor
  • Faulty oil pump
  • Wrong engine oil filter
  • Faulty electrical connections to the engine oil pressure sensor
  • Lower engine oil level
  • Short or open circuit of the oil pressure sensor
  • Dirty engine oil

How to troubleshoot & fix the P06DD Jeep Wrangler code?

The engine oil sensor complications often trigger the P06DD code in the Jeep Wrangler. 

Since there are various possible reasons behind the problem, you can’t stick with a single solution. 

Therefore, we are adding some relevant fixes below to help you solve the problem. 

Inspect and Change the dirty Engine Oil 

Start by inspecting the oil level and its condition. Continuous operations make the engine oil filter collect debris, dust, and unwanted agents. 

As a result, the engine oil becomes dirty over time and requires an immediate change. 

But if you delay the change, chances are your engine getting affected, which can result in detecting the P06DD code in the Jeep Wrangler. 

To identify whether the engine oil is dirty, you should inspect whether it got darker and thicker from its original state. 

We’ll let you know about the oil change procedure in the steps below. But while carrying out the steps, ensure you have all the tools like jack stands, pliers, screwdrivers, containers, wrenches, etc. 

Therefore, let us have a look at the process.

  • Open the hood and start the process of removing the engine cover
  • Carefully use the tools to detach the components that are adhering the cover to the engine
  • Access the oil pan and remove the cap
  • Place the container underneath the car and remove the oil drain plug to let the container collect dirty oil 
  • Use the wrench to loosen the oil filter and then remove it
  • Remove the filter and replace it with a new one
  • Tighten the filter and then also change the drain plug
  • Add new oil to the pan and then tighten the cap that you removed before

Replace the Oil Pressure Sensor

Next, the most important element to look at is the oil pressure sensor and electrical connections to the engine oil pressure sensor. 

When the engine oil pressure sensor gets affected, the job becomes quite hectic in the case of replacement. 

You must access the oil cooler first and then replace the sensor. The breakdown of the steps in this process are as follows:

  • Take out the engine cover after opening the hood
  • Use a wrench and pliers to unhook the air intake inlet
  • Start the intake manifold removal
  • Carefully detach all the brackets and hoses for the upper intake manifold
  • Take out the upper intake manifold
  • Access the lower intake manifold and loosen all of the electrical connections
  • Ensure that you have unplugged all the engine harnesses and injectors
  • Access the oil filter housing and cooler, then take it out carefully
  • From the oil filter cooler, replace the faulty oil pressure sensor with the new one
  • Reverse the entire process stated above and reassemble all the parts

Locate and take measures to fix leaks

Engine oil leaks are common, which can lower the engine oil pressure. As a result, you may detect the P06DD code in your Jeep Wrangler. 

You can determine whether there is a leak in engine parts by discovering a puddle of oil beneath your Jeep Wrangler. Apart from this, some other methods of locating the leaks are mentioned below:

  • Remove any plastic covers if required, and use the flashlight in parts to view where it is tough to access
  • Apply talcum powders in the locations where you suspect the leaks are. Drive the vehicle for 10-20 minutes; the leaks will be visible in the areas in the powdered area

  • Use a 19 mm socket to rotate the crankshaft
  • Take out all the oil pan bolts
  • Pry the oil pan cautiously by not to damage its surface 
  • Remove the bolts holding the oil pump to the engine block
  • Add some slack in the timing chain that has the oil pump
  • Clean the surface of the place for the oil pump and get rid of sludge
  • Set the new pump following the manual
