Start your vehicle and let it sit idle for around 7 minutes. Moreover, set an auxiliary fan in front of the radiator if it tends to overheat. The cooling system needs to be at the right level, and there needs to be enough oil in the car. Therefore, you should park your car in a well-ventilated area. While I understand that you are eager to have the catalyst monitor ready, keeping the vehicle safe during this process should be a higher priority. What if I told you that your monitor could be ready in just a few minutes? Sounds incredible, doesn’t it? Let me show you how it is done. This may occur when the monitor cannot read the drive cycle data because the engine control unit (ECU) is blocking it. However, it is possible that you have driven the cycle, but the monitor is still not working. I stated earlier that the monitor could be incomplete due to a lack of the drive cycle. In that case, the monitor won’t run without indicating that the issue is with the gear position sensor.
If it malfunctions or requires replacement, the car will not appear in drive mode, even when driving at 60 mph. I apologize if this sounds a little crazy your gear position sensor may be at fault for the catalyst monitor not being ready. Replacing them is the only way to resolve this. What you should know is that they may still function well and even PASS while having various issues. Okay, I hear you when you say your O2 sensors seem to work perfectly. O2 or AF SensorsĪnother reason why the catalyst monitor is not ready is poorly performing oxygen sensors. Every car has a unique drive cycle based on its manufacturer, model, and year.

The driving cycle, also known as the driving pattern, refers to a series of driving instructions that must be followed for the monitor to function. If you have not driven your ‘driving cycle’, the monitor will not be complete. There are only a handful of reasons why the catalyst monitor might not be working. In the next section, I will explain what they are. You have to meet certain conditions to make the device work. However, just because the monitor is not running does not mean your vehicle is malfunctioning. They solely rely on the O2 sensors of the car, which rarely give incorrect readings. More often than not, catalyst monitors are accurate. You will experience lackluster acceleration, poor engine performance, and dark exhaust smoke if the conversion stops. A catalyst monitor ensures that the converter is performing conversions as necessary. If the status does not switch to COMPL (complete), restart the engine, make sure that the preconditions have been met, and then perform the Monitor Conditions again.The catalytic converter of the exhaust transforms toxins into less harmful substances, such as CO2 and water vapor. Check the Readiness Monitor status displayed on the tester or scan tool. Connect a hand-held tester or OBD II scan tool to the DLC3.Ĥ. If the engine is started, the step described above must be repeated.ġ. HINT: Do not start the engine until checking Readiness Monitor status. Turn the ignition switch to OFF and wait for 6 hours. Vehicle was driven in the city area (or on free-way) for 10 minutes or more.ġ. The intake air temperature is between 4.4 degree C and 35 degree C (40 degree F to 95 degree F). The engine coolant temperature is between 4.4 degree C and 35 degree C (40 degree F to 95 degree F). The altitude is less than 8,000 ft (2.,450 m). If it does not set then there is a continuing issue with the system. Follow that suggestion and it should run. I posted below the process that needs to be done to run the monitor.

Was there a code that was repaired for the EVAP system?
