not to hijack your thread or anything, and i know there's a million reasons why this could happen, but was this resolved? i'm having a similar issue, but with some strange details to go with it...

 

I just plugged in my scan tool tonight and it told me crankshaft positioning sensor so I am goin gto go from there i will keep this updated.

 

please keep us updated, i had the same problem today and i changed the CPS 3 times and it still did the same thing. I am thinking its the flywheel

 

i think thats the cause

i had a engine replaced and had the same problems. first it only happened when i went past 4k rpm, then 3, then 2. worst of all it happened at a meet so everyone thought i was a noob driver. needless to say i had it towed and turned out it the crank shaft position sensor wasnt seeped in right.

 

that is the exact same thing that is messed up with mine only mine was at 3 k then 2 then 1200 i am calling nissan canada tomorrow and see wha tthey say about the recall then call the dealer it is said to have a bad solder on one of the wires. I will keep you guys posted.

 

did you plug a scan tool into it or anything? or did you just change it because?

 

koo gluck.

 

this happened when i was on the dyno at Injected Performance. Hal plugged in the scan tool and it threw the a cps code, changed it out with 3 known working ones, swapped out the ecu, swapped out the haltech and the patch harness and still nothing. Hal ended up putting a scope on the voltage output of the crank position sensor and it had a very bad voltage signal. They think it is probably the flywheel

 

what do you mean by "seeped in right"?

 

thats what the work order said. prolly not secured tightly?

 

why would the flywheel have to do anything with it. I did just have a new one put in

 

the flywheel has a plate machined on to it with little teeth notched out of it. That is what the crank position sensor reads off of. If there is a defect in the flywheel or it is slighly deformed then the sensor will not be able to count the teeth correctly and confuse the hell out of the ecu

 

btw i also have an exedy clutch and flywheel, so that is a common link

 

ya i have a clutch masters flywheel

 

I am pretty sure i figured out my problem. i got under my car with alot of trouble only having a scissor jack. i found my sensor was actually loose and hung out a quater inch as you read this I am going to try my car right now.

 

ok so it was the sensor loose. thanks for all the help.
