Spilled some engine oil while topping up on this marked area. Will it cause any problems?

 

It shouldn't cause any issues as the pins are fairly well sealed where they insert into the connector. They have a weather resistant rubber seal so to speak around the end of the crimp point. Those seals usually do a decent job protecting from moisture and in this case, a little bit of oil.

If you are concerned about it, unplug the connector and spray it with brake clean and blow it dry. I don't suspect any oil made its way to the pins but I suppose it's worth a look.

 

Welp, that's a rebuild.


It's quicker to clean up than to make this post

 

What is that sensor btw?

 

purge valve solenoid or PVS
