That requires an OBDII engine scanner.
It requires an engine scanner to do that.
I have the check engine light on and the code is for map sensor on my 1999 1500 Chevy suburban
How do I reset the service engine light on a 2003 Chevy Trailblazer?
can you tell me why my 1999-2000 Chevy trailblazer light is on
Maybe you should service the engine soon. :P
There is a problem with the emissions system. You need to have the engine scanned with an engine scanner to be able to find out what is wrong and then FIX the problem that made it come on in the first place. Then clear the codes and it will go off.
When service engine light is on on a 2003 Chevy Trailblazer, the problem could be a faulty thermostat, a circuit range performance problem, or any other problem.
That requires an engine scanner to do that. If you don't repaire what made the light come on in the first place it will just come back on.
You need to have it checked for codes to know what the cause of the code is.
