What does Error Code P06DE mean?
Moderate Issue
DTC Code P06DE indicates a malfunction in the engine oil pressure control circuit, specifically related to the ON signal. This code is applicable to vehicles with generic systems.
What are the symptoms of Error Code P06DE?
- Illuminated Check Engine Light: The check engine light may illuminate on the dashboard, indicating a malfunction in the engine oil pressure control circuit.
- Erratic Oil Pressure Readings: The oil pressure gauge may show erratic or fluctuating readings, which could be linked to a malfunction in the oil pressure control circuit.
- Engine Performance Issues: Drivers may experience reduced engine performance or unusual engine behavior due to improper oil pressure regulation.
- Unusual Engine Noises: There may be unusual noises from the engine, such as ticking or knocking, which can be associated with incorrect oil pressure levels.
What causes Error Code P06DE?
- The engine oil pressure control circuit may have a faulty oil pressure sensor, leading to incorrect readings and triggering the code.
- Wiring issues such as damaged or corroded connectors can disrupt the signal in the oil pressure control circuit.
- A malfunctioning oil pump can cause inadequate oil pressure, resulting in the control circuit malfunction.
- Low engine oil levels or degraded oil quality can affect the oil pressure, causing the control circuit to malfunction.
- ECU software issues or glitches may lead to incorrect interpretation of the oil pressure control signals.

How to fix Error Code P06DE?
- Verify DTC Code: Ensure the DTC P06DE is active and not a stored or historical code. Clear the code and see if it returns after a short drive cycle.
- Inspect Engine Oil Level and Quality: Check the engine oil level and quality. Low oil level or degraded oil can affect oil pressure control. Refill or replace oil if necessary.
- Examine Oil Pressure Sensor: Inspect the oil pressure sensor for any signs of damage or disconnection. Ensure the sensor is properly connected and functioning.
- Check Oil Pressure Control Solenoid: Test the oil pressure control solenoid for proper operation. Ensure it is receiving the correct voltage and is not stuck or clogged.
- Inspect Wiring and Connectors: Examine the wiring and connectors related to the oil pressure control circuit for any signs of damage, corrosion, or disconnection.
- Perform Oil Pressure Test: Conduct a manual oil pressure test using a mechanical gauge to verify the actual oil pressure against the manufacturer's specifications.
- Evaluate Engine Control Module (ECM): If all components are functioning correctly, consider the possibility of a fault in the ECM. Reprogram or replace if necessary.
