SB17-067 Countermeasure for VALVE ASSY OIL CTRL 2013-2017
Solving Internal oil leakage with new 10921AA241
Check part as described.


I changed the lower drive side one thus had a oil leakage generating some VVT code.

Is this a preventative thing, or a will repair thing ?

it's a countermeasure, "IF"

Is this the cause of all the ignition coil codes?

sometimes may occour VVT DTC code if conductivity is poor. I got VVT DTC code and solved this way, you need ring and back ring too when change.

NO, it doesn't affect ignition, only VVT system

what exact code did you get?

I noticed my left hand side upper OCV sensor has this oil contamination in the electrical plug connector.

I haven't gotten a CEL yet, and it's been roughly 3,000 miles since I noticed.

I bought a spare OCV sensor to have on hand, should I change it out now? Or wait till a CEL to eventually come on to replace the sensor?

On a side note, I always use dielectric grease on all my engine harness connectors to prevent corrosion from the elements (if they don't have a rubber/silicone weather seal in the plug), wouldn't this oil contamination have the same effect as dielectric grease?

@Sigh-on-Rice I think this warrants being added to the sticky

I had this replaced without a TSB a few years back. I had no check engine light or any drive-ability issue. I only saw an oil leak seeping out.

Thanks for letting me know.
Thanks also to OP for posting this.
