It's possible driving 100 miles was not enough to complete your Camry's catalyst and EVAP monitors. We usually recommend driving 200-300 miles over the course of a few days and in both city and highway traffic. In most cases, the emission monitors run and show their status as completed during this time period. Due to individual driving habits and patterns, sometimes the criteria required to get a particular monitor to initiate and/or complete is not met. In such instances it may be required that a specific drive cycle pattern, designed by Toyota be followed. There are two driving patterns which we indicate below that will require you look up your Camry's engine class number. You'll find this information on the Underhood Emissions Label. Select the drive cycle which pertains to your engine class.
Notice: Take extra caution when performing the drive cycle on public roadways. Perform the drive cycle at your own risk. If you feel you may be unable to perform the drive cycle below safely, please seek assistance from a reputable smog check repair station or Toyota dealership.
Preconditions: (Make sure you have between 1/4 and 3/4 fuel in the gas tank. The EVAP test will not run while your Toyota Camry has a full tank of gas or the gas tank is near empty). Ensure there are no pending or active trouble codes and that the check engine light is not on.
