How to Reset the Engine Lights on the Chevy Monte Carlo

by Justin Cupler

The Monte Carlo received the axe treatment in favor of the more family friendly Lumina in 1988, but it made a return in 1995 as a toned-down, front-driven coupe. In 2006, the Monte Carlo somewhat returned to its muscle-car roots, when Chevy equipped it with a 5.3-liter V-8 that pumped out 303 horsepower and 323 foot-pounds of torque. The Monte Carlo's production ended following the 2007 model year, and resetting the check engine light in your 2007 model is simple and straightforward.

Turning off the "Check Engine" Light

Move the driver seat as far back as it will go to provide the room you need. Look under the driver side of the dashboard, just above and to the side of the accelerator pedal, and find the trapezoid-shaped plug. This is the OBD-II diagnostic port. Plug the OBD-II scanner into the diagnostic port, then turn the Monte Carlo's ignition to "Run" without starting the engine. Wait for the OBD-II scanner to communicate with the vehicle, then scan the codes via the scanner. Each scanner varies in this process, so refer to the scanner's manual for details. Write down these codes, then delete or erase the codes with the scanner. The deleting process also varies between scanners, so refer to the manual for specifics. Once the scanner completes its deletion process, turn the ignition off, turn the scanner off and unplug the scanner.
