The engine and whole electrical wire harness had caught fire and the car burned up with 3-5 minutes. I had to throw it in park and jump out because the peddles quit working and the car exploded in flames and had I not had my window down I would have been locked inside and could have lost my life. Also, if the computer isn’t the issue, then it means one of the other sensors is probably off if the car isn’t able to. It isn’t able to use the tables programmed in it to guess the amount of fuel needed. People passing by were honking and said the underneath of car and under hood had flames in front of car. If the car dies when you disconnect the mass airflow sensor, then that means it was working right and that your computer has issues. I soon lost all power including gas & breaks and windows. The following day after putting gas in the car I was leaving gas station and lost acceleration again and the car smoked again.

Whatever the reason for P0101 in your Chevy HHR, ignoring it is a bad idea.My 2003 montee ss had been smoking and having problems accelerating & shifting and put on testers and read code and I needed a air flow sensor so I had that put on, was recommended I get tune up so I got that, and had just put new battery in the car. Clogged Catalytic Converter– If you are getting P0101 in your HHR accompanied by a noticeable lack in power at speed, it may very well be that you have a clogged catalytic converter.

At this point if you use the YouTube video above in the MAF sensor dirty section, and there turns out to be no voltage at all, try checking out How to Find an Electrical Short on Most Any Vehicle from BackYardMechanic If you don’t see any you can use a multimeter to test the wiring. This leads to excessive fuel consumption, poor fuel economy, and possibly detonation. If the ECM is reading low or no vacuum, it assumes the engine is at high load, so it dumps in more fuel and advances spark timing. Start by inspecting the wiring harness for obvious damage. Here are the key problems to look out for: Poor Fuel Economy.

The second is that it only takes a few minutes to test it with a multimeter. 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 Chevy HHR. Since P0101 has to do with the Mass Airflow Sensor, which is a huge part of a computer controlled engine’s combustion process metering. Release the safety clip and gently pull the connector from the sensor. The engine’s computer uses this reading to determine the exact amount of fuel that the engine needs for optimal combustion. When replacing a mass air flow sensor, first locate the sensor which is positioned in the air intake tube between the air filter housing and throttle body. 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. With the Chevy HHR, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem.
