Hello,

I am also glad I found this site.  I have an 04 Titan that has the same problem.  (ticking under acceleration)  I took the truck to the garage three times, drove with two technicians and have a call to the Nissan customer service center about the problem.  The posts at this site have given more information than Nissan and the dealer combined.  My question is:  Would it be possible for you to give more information on ware the ground wire that goes from the block to the firewall is located, or a picture?

Thanks for any replies

     This noise almost made me go insane last Sept.  I dissassembled the glove box and air box trying to find the noise because I swore the noise was inside.  The ticking would only occur under a load, so simply revving the engine in park would not create the noise. Anyway, to simplify the story; I found the same tiny black wire, low on the passenger-side firewall running perpindicular to the aluminum a/c compressor line.  I thought damn, I wonder if that tiny wire is smacking the compressor line when the engine rocks.  I grabbed a trusty cable tie, tied the wire to the aluminum line, and voila.  The cable tie is still there, the noise is not.

     I fortunately do not seem to have a grounding issue.  I have never heard the ticking again. Hopefully this helps someone keep their sanity.
