But I don't know how a DSC fault would cause the crank sensor code, plus it did that fairly reliably once per drive, usually within 5 minutes of start up for 3 or 4 days before it went into limp-home mode. On a couple of those occasions I was at a stop light at the idle just dropped from the usual ~750 down to a struggling ~400 until I blipped the throttle. It's now been almost 3 weeks with zero recurrence.
Did you try running with DSC off at all? To see if it had an affect? That's what I am doing at the moment. Did you take any remedial action? Did you find out what caused it?
