Vehicle Emission Monitor- Drive Cycle
Have you failed smog for an incomplete emission monitor? Try this generic drive cycle. It's important to note that the specific drive cycle procedures can vary depending on the make and model of the vehicle, as well as the type of emission monitor being tested. Additionally, some monitors require specific driving conditions or engine operating temperatures to activate. Therefore, it's always best to refer to the vehicle manufacturer's recommendations or consult with our qualified mechanic here at Anderson Smog Shop in Anderson, CA.
Cold Start:
Cold Start: Begin with a cold start. This means that the vehicle should not have been driven for at least 8 hours and the engine should be at ambient temperature.
Idle
Idle: Let the vehicle idle for 2-5 minutes with the air conditioning and defrost turned off. During this time, the oxygen sensor, catalytic converter, and other monitors will start running their self-tests.
Acceleration
Acceleration: Accelerate the vehicle smoothly to a speed of 25-30 mph and maintain that speed for about 2 minutes. This will activate the EGR and EVAP system monitors.
Steady Speed
Steady Speed: Drive the vehicle at a steady speed of 45-50 mph for about 10 minutes. This will activate the oxygen sensor, catalytic converter, and other monitors
Deceleration
Deceleration: Decelerate the vehicle smoothly to a stop without applying the brakes. This will activate the fuel system monitor.
Stop-and-Go Driving
Stop-and-Go Driving: Drive the vehicle in stop-and-go traffic, with periods of acceleration and deceleration, for about 10 minutes. This will activate the misfire monitor.
Highway Driving
Highway Driving
