I have a 2006 Monte Carlo SS, 5.3 L check engine light came on and dealer stated it was the #2 bank sensor (evap sensor) and they want $650 to replace it. Live on S.S. and would like to save money. Do you know where I can find the sensor and is it something I can do ??

 

They probably mean the O2 sensor. Go to Autozone, Oreilly or Advance auto and they will read the codes for free. Then you can post those codes and it would be then easier to answer your question.

 

The 2nd O2 sensor is under the car before the catalytic converter. You'll need a lift or ramps to get under the car.
