Code 11 crank position sensor? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I was driving my car in an autocross and on a fun run at the end of the day I noiced thr car seemed down on power, on the way home it really felt weird, bogging, no power etc. I really noticed it when blipping the throttle for heel toe downshifts, the rev's wouldn't come up as fast as they should. Once I got home I checked the codes and came up with 11. Since the sr has no CPS, it has a CAS so there must be some sort of malfunction there. Now I know if the cas was totally dead, the fuel pump wouldn't even turn on but it does so I guess my question is has anyone ever seen one of these go bad in this way? Causing loss of power and or hesitaion?

After a very hard stop from high speed, my car threw codes 11 and 21, crank and cam sensor. I had severed the crank sensor wire in the harness where it turns from the back of the motor onto the firewall. It took a while to figure out where the open circuit was. The symptoms were that the car would lose ignition on moderate to hard stops.

Sounds different from yours, but there's my story. Damn Z32 brakes!
