CRANK POSITION SENSOR CIRCUIT MALFUNCTION
So, this started with an intermittent stating issue. Car wouldn't want to start when engine was warmed up, figured it was CPS so I bought a duralast one from autozone. Threw it in, no issues fired right up, reved it up to 3kish for about 50 seconds to recalibrate or whatnot I read on a DIY fourm post. Car would pop under a hard acceleration and shut right off, so i stopped pushing it and drove normally for a week, but last night I was merging onto the thruway and I hit redline, lost throttle, car reved all the way from redline to 1k rpm and just died. I get code crank position sensor malfunction. P0335, No idea what the fuc is goin on anymore with this thing. any help is appreciated fellas <3

The rpm rev in park is simple enough. My question - is there a trick to the last procedure besides burning my brakes on a far-away, empty road? STAR indicates it wants this test done in 3rd gear, which is about 45 mph at this rpm, and to get anything over 20% load I have stand on the brakes while keeping the speed up. If I didn't I'd be at redline way before 30 seconds is up. I've tried it once and was pretty confident I kept it above 50% load and 2100rpm, and it was about 40 seconds, but nothing changed on my learning chart...
Or is the rev in Park trick enough? The document called it a 'quick procedure', so does it replace the road test one or do both have to be performed?

I now use only the rev in Park trick. Like you, I felt I was burning up brakes. Once the first box was adapted, I just started driving the car as usual. I would check with STAR every week and eventually all indicated adapted.
