The diagnostic code 410, on your 2004 Chevrolet trailblazer, is a reference to a vacuum hose problem. Check the vacuum hoses to make sure they are all connected.
how to diagnostic this code
The only way to know for certain is to read the diagnostic code. Code readers are becomming quite inexpensive and in my opinion, everyone should have one.
The diagnostic code should go off when the issue is fixed. You can try disconnecting the battery for a few minutes. Also, it can be reset through a code reader.
"Check Engine" usually means that the computer has stored a diagnostic code. Use a code scanner to find information about the stored code.
Based on numerous internet searches the code means you check engine light is on.
Start by changing the bulb in the check engine light. If that does not cure the issue and this code comes back up you need to figure out what other code is up and repair that. This code indicated that 1st the bulb or circuit controlling the Check engine light is faulty or that the engine computer has run a diagnostic check and one of the systems failed.
More than likely, its probably the oxygen sensor. The best way to determine why the light is on is to read the diagnostic code. There is a procedure to get the engine "Check" light to flash the diagnostic code; or you could take it to a dealer for them to read the code. By the way, the oxygen sensors should be replace every 70,000 miles.
code 401 means A required change in air/fuel mixture was not detected during diagnostic test. Check for faulty EGR Valve-vaccumn line leak. Should not be to difficult to isolate
