There is a green "POWER" light that comes on this 2004 Chevy Tracker. The light simi circular in the lower right corner of dash. There is no mention of any kind of power light in the owners mannual. The local chevy service dept. has no idea?? Can you help me?
it means you have a sensor that controls the cars fuel out put when you give it gas
The power indicator light on a 2003 Chevy Tracker typically indicates that the vehicle is in "Power" mode, which allows for enhanced acceleration and responsiveness by altering the transmission shift points. This feature is often used for situations requiring more power, such as towing or driving on steep inclines. When the light is illuminated, it confirms that this mode is active; turning it off usually returns the vehicle to standard driving mode. Always consult the owner's manual for specific information regarding indicator lights and their meanings.
you mean knock sensor
It is not a "warning" light but an indicator that you have pressed the button near the shifter to put the tranny into tow mode.

I'm assuming you mean the upstream O2 sensor, which is "upstream" of the catalytic converter in the exhaust manifold or pipe.
