How to Troubleshoot & Fix P06DE Jeep Wrangler DTC Code?

As convenient as ECM codes can be when identifying engine issues, they can also be confusing. One of these codes is a P06DE code! This code is set by the control module or ECM of wrangler when it detects an issue with the oil pressure sensor. 

No Need to be worried. We will discuss every detail, including the meaning, reasons, and fixing strategy to eliminate the code P06DE. Keep reading to find out more!

What Does the P06DE Jeep Wrangler Code Mean?

The P06DE code is mainly a powertrain code that indicates the engine oil pressure is above the recommended threshold for 250 seconds or more. This particular code is detected by your car’s ECM (Engine Control Module). 

To be clear, the code indicates an issue with the engine oil pressure regulation system. The code may occur due to a faulty solenoid valve circuit. 

If the solenoid valve circuit isn’t working properly, it may disrupt the engine oil flow and pressure. The ECM then detects the issue and shows a P06DE code, causing the oil pressure control circuit to be stuck off. 

Here is a breakdown of the P06DE code: 

• P = Indicates the powertrain of a vehicle.   
• 0 = Indicates the code is derived from the SAE standard.
• 6 = Indicates onboard computer and other output issues. 
• DE = Indicates specific issue; Engine oil pressure control circuit stuck off. 

P06DE Code: What Causes Engine Oil Pressure Circuit Stuck On Problem on Jeep Wrangler?

Three things can cause a P06DE code. The main one is a faulty pressure sensor. This pressure sensor ensures the engine oil stays within the calibrated threshold. 

Apart from that, some other causes can be low oil levels, wrong oil viscosity, etc. Also, the other reasons for which the code is present are given below:

• Faulty oil pressure sensor
• Engine oil or mechanics failure
• Dual-stage oil pump

How to Troubleshoot & Fix P06DE Jeep Wrangler Code?

Now that you know the causes of a P06DE Jeep Wrangler code, it’s time to learn how to troubleshoot and fix it. 

As there are three main causes, we’ll go into the details for each of their fixes. So, here is how to troubleshoot and fix the P06DE Jeep Wrangler code: 

1. Ensure the Oil Pressure Sensor is Sending Accurate Readings

Sometimes, your Jeep Wrangler’s PCM may show a false alert. And regarding DTCs, it’s always best to check and ensure an error code is accurate before troubleshooting. 

If the DTC is checked and found to be false, the oil pressure sensor may malfunction. 

Start by clearing out the DTC and putting your engine through a test run. Make sure your car’s engine reaches normal operating temperature. 

With your scan tool, check to see if the error codes re-appear. If the P06DE code doesn’t show again, the code is likely a false alarm. 

Also, check for any additional DTCs. If any do appear alongside the P06DE code, treat them. To check for an active DTC, you will need a scan tool.

2. Check for Engine Oil or Engine Oil-Related Issues 

If the P06DE code seems to be accurate, check for any engine oil or engine oil-related issues. As we mentioned earlier, P06DE is an engine oil pressure-related issue. 

So, low oil levels, dirty oil, contaminated oil, or having the wrong oil viscosity can cause the pressure sensor to not work properly. 

Also, having an oil filter that doesn’t meet the OEM specifications can cause a P06DE code in your Jeep Wrangler. 

To fix this issue, maintain the right oil levels, accurate viscosity, and proper car maintenance, and ensure you’re using the clogged-free oil filter. Also, look for built-up engine sludge, which tends to cause many engine oil-related issues!

3. Check for Damaged Dual-Stage Oil Pump

If all the above-mentioned oil-related issues are ok, check for a damaged dual-stage oil pump in your Jeep Wrangler. A damaged oil pump or solenoid is one of the prime causes of a P06DE code. 

However, we kept it at last as the oil pump cannot be repaired and needs to be replaced! The oil pump comes as a two-part assembly, and the solenoid is a part of it. 

But, before the replacement, we need to run a quick test to ensure the P06DE code is active. 

And if you have already gone through step #1, proceed accordingly. If the P06DE code is active and returning, the dual-stage oil pump must be replaced. It’s best to contact a professional for major component replacements such as this. 

A dual-stage oil pump replacement for your Jeep Wrangler will cost you about $700-$900, excluding the labor costs. The labor costs will range from $200-$400 depending on the quality and labor.
