A thread revival but this issue is what I have experienced for three and a half years. It does not respond to throttle position very irregular with no real cause we can find.

ZD30 manual 2006. Not in the Vin range for replacement TPS.

I have NADS fitted and it is not showing over boost. My mechanic did back of the Turbo boost anyway but no improvement.

I had a new TPS fitted nineteen months ago and the issue went away for ten months before starting again.

I have today had the wiring harness checked and no issue. It failed again today while the auto electrician was driving with his diagnostic reader connected and again it read TPS fault. It has read this each time at my mechanics as well when it plays up.

It is past warranty with Nissan for that part at over $800. Do these things fail like this as the fault is identical? It will not accept acceleration then a few seconds later it works again.

It can go six months and not fault then it can do it often for a few days.

We have gone through so many things trying to resolve it. Fuel filters as well replaced. We think we have it beaten and back it comes!

Any advice appreciated.
