Wanted to see if anyone else is having this problem. I have a 2005 base and
have had the crankshaft sensor changed out twice (The car went into fail safe mode both times). Yesturday, I was on the Interstate doing around 80 and the car jumped into fail safe mode again. I don't have any engine mods, the only thing I have done to the car is upgrade the stereo with new speakers and an amp. Any ideas???

 

Yea...i have a 2005 model and my crankshaft sensor went out on me but thats it. It's driving ok now...sorry to hear yours went out on you 2 times!!!

 

man nissan makes some really bad Crank position sensors. If the car doesn't recive a RPM signal it wont function correctly and will shut off or use another sensor to get information from. Really sucks thought .. This was a common problem on sentra's too.

 

Yup it happened again this morning on the drive to work UUUGGGHHH ....i was on the freeway going at about 90mph then all of the sudden it started to choke i'm like WTF not again!!!
i let my foot of the gas pedal and let it roll...at about 40mph i dropped it back in 4th then it's alive again WTF!!!

 

I had the same problem with my '03 Z. the car would cut out between 3000-4500 rpms. and the check engine light would go on. I got mine replaced under a recall. I had no idea the '05s had the same problem

 

This past Friday while traveling at 60MPH my engine shutdown. Fortunately I was able to coast to the side of the road. My Z won't restart immediately. After about 2 minutes I got it to start but the "Service Engine Light" was on. Proceeded about another mile and the engine cutoff again. After restart, "Service Engine ASAP" "VDC" and "SLIP" lights were on.

Took it to the local Nissan dealer who diagnosed a malfunctioning Crankshaft Position Sensor. Part was underwarranty (2005 Z) so no charge.

 

man wasn't that embarrassing...? having to slow down and POS cars just zooming by while i have my hazards lights on
