When you guys say CPS, do you mean the Crank Position sensor? CPS is the cam position sensor. CKPS is the crank. If you mean Crank Position sensor, I say another vote for it. My car was shutting off randomly and wouldn't let me start back up no matter what for at least a minute. I took the harmonic balancer off and checked the CKPS. It had some metal shavings between the teeth. I cleaned it with brake parts cleaner and wiped it down. Didn't have the problem afterwards. Worth a shot before replacing the sensor. You'll need an impact with good power and possibly a puller to remove the harmonic ballancer. I think I used M6x70 or M6x80 bolts with the puller. Just have to remove the plastic splash guard and the front passenger tire to access it.
