For about a year now, I was constantly getting the Very Small Vacuum Leak code on my 2013 JKU. I would erase the code with my code reader but it would keep coming back on within a day.
I did a lot of research and a lot of people said that they replaced the vacuum leak detector pump and the o-ring gasket. I bought it last week from Rockauto.com for about $30 and I installed it this past weekend.
I erased all error codes and now after 5 days, the check engine light has not come back on. Usually the light would come back on within about 10 miles of driving. Keeping my fingers crossed.
The dealership parts department told me that there is a new part number for the pump so hopefully they changed and improved the design of the pump. The new Mopar part number is 4861962AC.
