Why is my catalyst Monitor Not ready?
If the oxygen sensor and catalyst monitors are also not ready, the culprit is most likely a weak battery. If your battery is more than four years old, replace it and re-run the Drive Cycle. Even though your car may start just fine, the PCM is hypersensitive to the slightest glitch in the battery.

The vehicle must then be driven in stop-and-go traffic conditions at five different cruise speeds ranging from 25 to 45 mph over a period of 10 minutes.

How do I test my monitor readiness?
To check if the readiness codes are set, turn the ignition switch to the ON (II) position, without starting the engine. The MIL will come on for 20 seconds. If it then goes off, the readiness monitors are set. If it blinks five times, the readiness monitors are not set.
How many miles should I set my monitor?
Normally, the required emission monitors should become ready simply by driving the vehicle for 200 to 300 miles and over the course of a few days… without needing to drive a specific pattern. During normal driving the ECU will perform the neccessary internal self-tests required to set the monitors.
How many miles do I have to drive to complete a drive cycle?
When you have accelerated up to around 60 mph and have safely merged into the flow of traffic, stay in the slow lane and maintain a steady speed of 55 to 60 mph for a minimum of five miles.

What’s the difference between catalyst monitor and non continuous monitor?
Whereas, non-continuous monitors need certain conditions like speed, ambient, acceleration, fuel level, and much more to carry its testing process. Catalyst Monitors are non-continuous monitors that assess the ability of the catalytic converter to decrease harmful emissions.
