I can't rev past 5500 rpm's?
 

So I can't rev past 5500 rpms, I don't know why or how or what's going on? As soon a get to 5500 my car suddenly goes into a weird limp mode like situation. Kind of sounds like a 2 step but I know it's not anything good... I replaced spark plugs, and idk how but it's throwing me a crank sensor code. I replaced the sensor and my cut off began at 3000 rpms. Doesn't make any sense to me. I have no other codes someone help?!!

Any check engine lights? error codes?

Was it throwing the crankshaft sensor code before you noticed that you couldn't rev past 5,500rpm's? Did you replace it with an OEM Nissan sensor or some generic crap? Just asking.

Yeah it's give me a crank sensor code

No it wasn't giving me the crank sensor code at all, nt until after I noticed the cut off on my rpms

It was an Oem nissan replacement

Oem or oem replacement.....big difference

did you get it from nissan?

^ This.

It was an Oem replacement not from nissan

Always always replace sensors with genuine nissan ones

So that cut off could be my crank sensor??

this has happened time and time again.... replace with non nissan sensors and still have error, replace with nissan and issues go away. there was a thread about this just the other day, let me see if i can find it
