What is the drive cycle for catalyst and oxygen sensor?
You will need 10-15 minutes of steady state cruising at 55-65 mph to run the oxygen sensor test. Cruise control works well for this. Do not exceed 65 mph or drop below 55 mph if at all possible during this portion of the drive cycle. After 15 minutes of minutes. This will trigger the catalytic converter test. After the 2 minutes of
Can a drive cycle fail to complete a catalyst monitor?
In most cases, you should be able to complete the catalyst monitor after following the drive cycle a couple of times. If several reasonable attempts at running the drive cycle fail to complete the catalyst monitor, a problem may exist that is preventing your vehicle from running the monitor to completion.
Can a lazy oxygen sensor cause a catalytic converter problem?
You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself. A technician can determine if the sensor is responding as it should.
How to do a catalyst monitor on a car?
Start the engine and bring the idle speed to 1,000 RPM’s for 6-8 minutes. allow the engine to idle normally for 2 minutes. Drive the vehicle at a steady speed of 55 MPH for 10 minutes. Stop the vehicle and allow the engine to idle in drive A/T with the brake pedal applied, in neutral M/T with clutch and brake pedals applied for 2 minutes.

Why is the oxygen sensor not ready for the drive cycle?
These constantly monitor the sensors, the fuel mixture, and the occurrence of misfires. If the oxygen sensor heater monitor is not ready, check to see how many other monitors are not ready. If the oxygen sensor and catalyst monitors are also not ready, the culprit is most likely a weak battery.
What should I do if my catalyst is not ready?
If the battery is detached or the catalyst is not ready, it might take five complete driving cycles to decide the status of the catalyst. For additional information about catalyst monitor, one can refer to maintenance tips by car experts.
