Toyota 4Runner Drive Cycle?

Pretty sure it’s the same for all Toyota’s made after 1998.

Start with cold engine

Idle until it reaches normal operating temp.

Drive around city roads for 15 minutes , no more than 40mph

Drive on highway for 15 minutes at steady speed , anywhere between 40-70mph , make sure it’s steady


Park car and let idle for few minutes.

Turn off and you should be good to go.
Should ready all monitors including catalyst.

If you throw a code at anytime you’ll need to fix the problem and try again.


You’ll find various methods online but they’re all very similar and the above has worked for me.
