I have a 2005 chevy colorado po442 and po506 codes problem

The code 442 is a small EVAP leak such as a gas cap or vac line to the canister.
Code 506 is saying the computer can not raise idle speed to where it needs to be. Could be a faulty idle air control valve or dirty throttle body.

Code 506 low rpm

First thing to do is clean the throttle body, that includes the front and back sides, make sure to disconnect the battery during the cleaning in order to reset the computer.
If this does not fix problem, look for vacuum leaks.

What does it mean code 300 and code 506. Thank you.

This P0506 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0506 DTC is triggered when the PCM detects an engine idle speed that is lower than the desired (pre-programmed) RPM.

Most likely the only thing you'll notice is the idle speed is lower than normal so it will likely be rougher. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL illuminates. Such as the P0300 which is an indication of multiple misfires to the spark plugs. 

A P0506 DTC trouble code may be caused by one or more of the following:

  • A vacuum leak 
  • An air restriction in the intake air path or exhaust
  • A faulty positive crankcase ventilation (PCV) valve
  • Damaged/failed/dirty throttle body
  • Internal engine problem
  • Failed PCM

Hope this helps, keep me posted if you have any more questions. Be glad to help you get your blazer running 100% again.
