yes, I believe it is a common problem. Apparently it was a common fault with the Aust delivered Pulsars of the early 2000's models where this part is common.
My car was showing the warning light on and clearing it self. As it got worse the motor would stop at random times at speeds up to 70km/h, so not the most enjoyable experience.
I had the part replaced, in my case, right bank (drivers side) and the problem was all solved. less a few dollars taken by the Nissan dealer.
Cheers
