Possible DTC P06DD After changing engine oil and filter

change due to oil filter being empty

Correction:

If you encounter DTC p06DD during the first start-up Immediately following an engine oil and filter change, clear the DTC using GDS and verify the code does not return.

This issue was likely due to the engine oil filter not being pre-primed with engine oil before installation causing low or no oil pressure on initial start-up.

If the vehicle arrives with DTC P06DD in history question the customer as to when the engine oil and filter was last changed. If the oil and filter was recently changed then clear the P06DD code using GDS and verify the code does not return. The above condition may have been induced if the engine oil and filter was recently changed at another repair facility.
