2002 Pathfinder Died today...
I was driving to work this morning and my Pathfinder quit on the highway. I was driving along and everything was fine and normal. I had the cruise set at 70mph. I started to smell something like burning wires, about 10 seconds later the engine quit and I coasted to the side of the road. It will not start. I had my boss tow it back to my inlaws place tonight and I am trying to figure out what happened. I have been looking for burnt fuses and found the ECCS 2 fuse was blown. My Father in law has
Unfortunately, that is a common problem with the Pathfinders that have the VQ35 and a cable controlled throttle. Usually it is a small coolant leak at the throttle body that drips coolant onto the idle control valve. Over time the valve gets damaged and requires more current to operate and causes the idle control drivers to burn out in the ECU.
Only real fix I know of is to repair/replace the ECU and replace the IAC valve. Make sure everything is clean and sealed.
