It was the first of two cam position sensors to break. They are easy enough to change. The front one is easy, the back on needs long skinny fingers and patience.

THIS IS BS I HAVE HAD TO REPLACE MY CAM POSITION SENORS 3 TIMES THIS WILL BE MY FOURTH. THEY LAST ABOUT A YEAR SAME AS THE WACC WARRANTY THEY OFFER. THE CAR WONT RUN ON AFTER MARKET SENSORS SO OEM IT HAS TO BE. BUT THEY ONLY LAST A YEAR. THIS BOGUS NISSAN IS BOGUS. MY CAR HAS STALLED ON THE FREEWAY WITH MY KIDS IN THE CAR. THIS IS A DANGEROUS ISSUE THAT NEEDS TO BE ADDRESSED. CARS ARE TOO DAMN EXPENSIVE TO BE STRANDED ON THE SIDE OF THE ROAD BECAUSE OF A LITTLE PIECE OF PLASTIC FU NISSAN !!!
