• Prolonged engine operation under high speeds with the air compressor in Low-Pressure mode might culminate in extensive engine damage.

Why Does the P06DD Code Appear After an Oil Change?

The P06DD code often appears after an oil change due to a lack of pre-priming the engine oil filters or other maintenance discrepancies during the process.

Understanding P06DD: P06DD is a diagnostic trouble code (DTC) that is triggered when the dual stages oil pump sensing element alerts the Powertrain Control Module (PCM) about a low oil level.

Root Causes of the P06DD Post-Oil Change

1. Initial Computer Response: On the initial startup post oil change, if the DTC P06DD surfaces, it’s advised to erase the code using GDS and monitor if it reoccurs.
2. Oil Filter Issues: Often, this problem stems from the engine oil filters not being adequately pre-primed with oil before installation, leading the p06dd engine oil pressure control circuit to get stuck off.
3. User’s Maintenance History: Always inquire about the last time the engine oil and filter were changed if the vehicle records show DTC P06DD. If the code appears shortly after a recent oil change, the lack of filter pre-priming is a probable cause.

Remedial Measures: Always erase the P06DD code using GDS after identifying the cause. If the oil change was done at a different service center, incorrect filter pre-priming is likely the issue.

Can I Drive with Code P06DD?

No, you cannot drive with code P06DD. Doing so might put your engine at a significant risk of severe damage.
