Not there to check your work.

But I'd remove power from the vehicle to unplug, plug in all connections associated with that code and remove the ground wire to give a little wire brush to the contact, clean and reattach. DC Meter won't check for good grounds.

I checked all the grounds seem ok. My son races dirt track and he thinks it's a mechanical issue. But not near here so he can't hear this funny pop sound.

Sorry

My thoughts were about the code and what others were sharing. As to the pop sound, my thought is that it could be a side effect from what is causing the code failure. Fix one and you may fix the other.

That's all I have for you today.
