  • Estimated Repair Cost: $20 – $600

What Does The P06DD Code Mean?

The P06DD diagnostic trouble code (DTC) is defined as “Engine Oil Pressure Control Circuit Stuck Off” and refers to a detected issue in the engine oil pressure control system. In this scenario, the engine oil pressure sensor is sending a message to the Powertrain Control Module (PCM), indicating that the oil pressure is below the acceptable level, thereby impacting the normal operation of the oil pump. 

The engine oil pump plays a crucial role in ensuring a consistent oil pressure supply. It functions with two pressure stages under regulation, which are governed by an on/off solenoid. The low-pressure mode, with the solenoid on, maintains a pressure of approximately 200 kPa (29 psi). Conversely, the high-pressure mode, with the solenoid off, increases the pressure to around 450 kPa (65 psi).

The minimum required pressure for the engine, under all operating conditions, is typically around 41 kPa (6 psi). When the oil pressure sensor indicates low oil pressure where higher pressure is expected, or if there is damage to the oil pump face, the PCM takes precautionary measures to reduce engine wear. It disables the oil pump drive and generates the P06DD code as an alert.

While the P06DD code can potentially occur in various vehicle makes and models, it is more commonly observed in certain brands. Some of the manufacturers that have reported instances of the P06DD code include: Dodge, Jeep, Chevrolet, Chrysler, etc.

In some cases, the P06DD code may be accompanied by additional diagnostic trouble codes, providing further insights into the underlying issue. Some of the common accompanying codes may include: P0521, P0522, P0523, and P06DE.

How Serious Is The P06DD Code?

The severity level of the P06DD code is moderate to high. Ignoring this code and continuing to drive the vehicle can potentially lead to serious engine damage. Insufficient oil pressure can result in poor lubrication, increased friction, and accelerated wear on engine components. Over time, this may cause engine overheating, decreased performance, and even complete engine failure.

If the P06DD code is detected, it is strongly advised not to continue driving the vehicle. Immediate attention from a qualified technician is necessary to diagnose and resolve the underlying issue. Continuing to drive with low oil pressure can have severe consequences and may result in costly repairs. It is crucial to address the problem promptly to ensure the longevity and reliability of the engine.

What Are The Symptoms Of The P06DD Code?

The P06DD code can manifest through the following symptoms:

What Are The Causes Of The P06DD Code?

The P06DD code can be caused by various factors, including:

  • Engine oil level or quality issues
  • Faulty oil pressure sensor
  • Malfunctioning oil pump
  • Clogged oil passages or filters
  • Wiring or connector issues in the oil pressure control circuit
  • PCM or software-related problems

How To Diagnose And Repair P06DD Code?

In this section, we will outline the essential tools and parts required for diagnosing and repairing the P06DD code, followed by a step-by-step procedure.

Diagnostic Tools And Essential Parts

To diagnose and repair the P06DD code, you may need the following tools and parts:

Step-by-Step Guide 

  1. Retrieve and evaluate trouble codes

Connect the OBD-II scanner or code reader to retrieve the P06DD code and any additional relevant codes.

  1. Check engine oil level and quality
  • Check the engine oil level and ensure it is at the recommended level.
  • Inspect the oil quality and consider replacing it if it appears contaminated or degraded.
  1. Inspect oil pressure sensor and wiring
  • Inspect the oil pressure sensor and its wiring for any signs of damage, corrosion, or looseness.
  • Ensure proper connection and secure any loose wiring or connectors.
  1. Test oil pressure sensor
  • Using a multimeter, test the oil pressure sensor to determine if it is functioning correctly.
  • Follow the manufacturer’s specifications for the sensor’s resistance values and compare them to the measured readings.
  • If the sensor goes faulty, consider replacing it.
  1. Inspect oil passages and filters
  • Inspect the oil passages and filters for blockages, restrictions, or debris.
  • Clean or replace any clogged filters and ensure proper oil flow through the passages.
  1. Measure actual oil pressure
  • Use an oil pressure gauge to measure the actual oil pressure and compare it to the manufacturer’s specifications.
  • Ensure that the measured pressure falls within the acceptable range for the engine.
  • If any parts become defective, such as an oil pump, repair or replace it.
  1. Clear the code and test drive
  • Use the OBD-II scanner to clear the P06DD code.
  • Take the vehicle for a test drive to ensure the issue is resolved and the code will not reappear.
