P0018 OBD-II Trouble Code: Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor A) P0442 TOYOTA - EVAP System Small Leak Detected P0022 - "A" Camshaft Position - Timing Over-Retarded (Bank 2)

So to answer your question no not all three, it would however triggerr the EVAP code p0442 , the other codes could have been original stored and just came out latter so cnacell all codes and see if any return.

I don't know where you got it from. obdII codes are usually...P0442 for instance.

p0505 is isc idel speed control ac valve /trottle valve sticking

P0505 Idle Control System Malfunction

IACV or Idle Air Control Valve if equipped is malfunctioning.

P0420 Catalyst System Efficiency Below Threshold (Bank #1)
The Catalytic converter is not working up to par in Bank#1.

I think this will point you in the right direction..

replace the IAC valve to resolve this issue.

P1442
The code actually has another character in front of it, most likely a P (Powertrain) code as they're most common, although it could also be a B (Body) or C (Chassis) code. So it's likely P1442 and it's description is Evaporative Emission Control System Leak Detected. That code is specific to Toyota vehicles, although it seems nearly identical to the generic code P0442. This error pertains to the emissions system in the car. You now have the choice of either taking the car to a qualified technician or you can try a few troubleshooting steps yourself. If you're not mechanically inclined, I would recommend you change the gas cap to a brand new Toyota one (not a cheap aftermarket one), reset the code and see if it comes back. If the code returns there are additional steps you can take. Take a look at this P0442 article for other ideas.
