Repair shop recomendations Nissan(sensor woes)

[JPS2345]

I have the FSM but followed the procedure to determine the issue causing the trouble code I pulled a P0335 Crank Position Malfunction...Im stumped, replaced the sensor, checked wiring etc.

It bogs/misses between 2k-3k RPMs and the tach is completely erratic.

Check your battery terminals/grounds and possibly look at at the TPS. The TPS could have some burned contacts in the "range" causing the computer to freak out.

This has been my experience on some other other cars i've had. And of course, check your plugs and other no money out of pocket easy inspection targets.
