The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
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
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.
If the check engine light code is "Random Multiple Misfirings", you need a tune up. Have the spark plugs and wires changed. The loss of power is due to misfirings.
disconnect the negative battery cable for 30 seconds
it could be a short or anti-pollution devices filters etc. check the vacuum on the charcoal cannister. 65;
That requires an OBDII engine scanner.
When a O2 sensor goes bad your check engine light will go on and set a code.
How do you reset check engine light for the 2009 Chevy trail blazer?
you need a scanner
When the check gauges light comes on then that means you have either lost all oil pressure are the engine is running HOT. It only has 2 functions and these are it.
You can either bring it in to a Chevy dealer or use a programmer/tuner to reset the check engine light.
