Default Low acceleration ping

Hello forum,

I looked this up and found reference to low oil, low octane fuel as possible causes. My oil was a quart low but the ping was still there after I added oil. Then I pulled fuse 35 to reset the timing which seems to have resolved the pinging.

Does this mean my knock sensor is bad? I will check the sensor with a multi meter but just looking for any other know potential causes.

Thank you for your insight!

Couple of things to try/look at assuming you are running the proper octane fuel =

Check/change air filter.
Put in "sport" mode and see if the ping goes.
Lastly, remove fuse #32, wait a few seconds, reinstall, this causes relearning of driving pattern. Just don't drive in "sport" mode for a couple hundred miles.

Dell, I recall reading something about being able to reset the OBC's "driving pattern", Does removing and reinstalling fuse #32 affect anything else?

#32 is the driving pattern reset - hence do not use sport mode for a couple of hundred miles.
