Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your 2005 Nissan Maxima. The catalytic converter readiness testing can take some time as well as the EVAP emissions. I recommend making sure you have a half tank of fuel or less to allow he EVAP test to run and pass. Anything over a half a tank of fuel in some cases can delay the EVAP system from running and passing. For the catalytic converter test this can take some time with extended driving under optimal conditions. There is a certain drive cycle I have used in the past that seems to work well, and you are welcome to try it. I will post it below. Keep in mind anytime you lose battery voltage in any way or reset any codes this will restart the process all over again. Cold Start The barometric pressure (BARO) is more than 81 kPa. The engine coolant temperature (ECT) is between (41-86°F). The intake air temperature (IAT) is between (41-86°F). The start-up ECT and IAT are within (16°F) of each other. The battery voltage is between 9-16 volts. The fuel level is between 15-85 percent. Important: Whenever the ignition is turned ON, ignition positive voltage is supplied to the HO2S heaters. After verifying the enable criteria, turn OFF the ignition for approximately 5 minutes to allow the sensors to cool before continuing with the test. Once the engine is started, DO NOT turn the engine OFF for the remaining portion of the set procedure. Turn OFF all of the accessories, Set the vehicle parking brake. Verify the transmission is in Park for automatic transmissions and Neutral for manual transmissions. Start the engine and allow the engine to idle for 2 minutes. Acceleration at part throttle to (55 mph) with this speed maintained until the engine reaches operating temperature. This may be up to 8 minutes depending on the start up coolant temperature. Continued operation under these conditions for an additional 6 minutes. Acceleration at part throttle to (45-55 mph) with this speed maintained for 2 minutes. Deceleration to (0 mph). Engine idling for 2 minutes while the following criteria is maintained: The service brake is depressed. The automatic transmission is in drive. The manual transmission is in neutral with the clutch pedal depressed If you need more advice, or have any further questions about your vehicle, we’re here to help.
