C1201 is exactly related to how the engine is running, but it's just the vsc system storing a code due to an engine control fault.
To quote the description for 0018:
"To monitor the correlation of the intake camshaft position and crankshaft position, the ECM checks the VVT neutral position against the VVT learning value while coasting. If the VVT neutral position is out of the specified VVT learning value range in driving cycles, the ECM illuminates the MIL and stores DTC P0016 (bank 1) or P0018 (bank 2)."
It trip on the 2nd drive after clearing because it's a 2 trip detection logic
