If you don’t see any you can use a multimeter to test the wiring. Start by inspecting the wiring harness for obvious damage. MAF Sensor Wiring– Make sure to check around the MAF sensor for opens or shorts.Without knowing how much air is really getting into the engine, P0101 will be thrown. Intake Manifold/Vacuum Leak– If there is a leak in the intake manifold, it will be impossible for the MAF sensor to get an accurate reading.Just make sure you check to make sure it fits your year Maxima before purchasing. If you do need one, they are pretty reasonable on Amazon. The second is that it only takes a few minutes to test it with a multimeter.
#2012 NISSAN MAXIMA MASS AIR FLOW SENSOR PROBLEMS HOW TO#
Here’s a video on how to test one without pulling it. MAF Sensor Failure– While it is very likely that the MAF sensor itself could be the problem, it’s absolutely necessary to test it before you replace it.Here’s a great article on exactly how to clean one from Family Handyman. They can be cleaned, but it’s easy to mess one up, and you don’t want to use a wire brush. MAF Sensor Dirty– Over the course of its life, the MAF sensor will often get so covered in grime that it’ll no longer get an accurate reading.They are presented loosely in order from most to least likely: Here are the most common causes of P0101 in the Nissan Maxima. Since P0101 has to do with the Mass Airflow Sensor, which is a huge part of a computer controlled engine’s combustion process metering. The engine’s computer uses this reading to determine the exact amount of fuel that the engine needs for optimal combustion. It measures the air density and volume in between the air filter and the intake manifold. It’s important to understand what the MAF sensor does. It should be considered a high priority to fix, as the MAF sensor not reading properly can really make an impact on the performance of the vehicle. We will cover exactly what that means and potential fixes for it below. Never use any of the 'cleaners' sold for the purpose.they only loosen up debris that then can clog the radiator and heater core further.With the Nissan Maxima, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. Refill with water and you have a clean system. Wait until it cools down.look in the radiator and you'll see what looks to be a brand-new inside. As long as you shut the engine down when it 'pops', you won't hurt anything. This will 'steam clean' the internals.you'll find residue all over once the show is over. At that point, all the water in the system will immediately turn to steam. When it gets high enough, the hose will blow off. Remember, your pressure cap is still protecting the system against overpressure. What happens here is that the water will get to above-boiling temperature and build up pressure. Wait in the driver's seat for the top hose to blow off. Keep everyone clear.this sprays boiling water (do this outside) and start the engine and let it idle. Then place a piece of cardboard in front of the radiator to block airflow. Put some cardboard in a position to keep sprayed water off any electrical stuff (alternator, distributor, starter, etc.). Then remove the clamp on the upper hose at the radiator. A cheap, shade tree fix that still works well today on dirty radiators is to drain the radiator, then refill with fresh water. Replacing the thermostat is a cheap diagnostic.do it. Two most likely culprits are bad thermostat or plugged radiator. If none, something is causing water loss through overheating. Only two ways for that to happen, a leak or running hot and boiling it away. i did not intend to make fun of your design, i just don't understand the function of the seperate resivior if the regular resivoir never drains? If/when you get it built we want pictures! darthhelmut I realized my previous post sounds really mean. you seem like you have a deeper interest in really understanding things so you might enjoy scientific type books though. I would not recomend these college level reference books to the casual gardener becasue they are very dry, scientific data that has not been dumbed-down for the masses the way the books the book store have. I think we spent 4-5 weeks on nothing but roots when i was working on my horticulture degree. If there is a local college near you, and you can access their library, you can learn more than you ever wanted to know about how and why roots work. I knew what you were talking about, i was just messing with you. I think sarcasm is often lost in text based communications. I know you can buy commercial units, but i think many home hydro growers enjoy designing and building stuff as much as they enjoy the growing its self. I'm still in the design/build/test phase, but if/when it works, I'll post details like a parts list and instructions. I'm working on a simple design for building an automated float valve system to replenish hydro-nutrient tanks. Tclynx- Look into float valves as they might help you out when tanks start to get low.
