Gm error code p0101

Mass or Volume Air Flow Circuit Low. What does that mean? This diagnostic trouble code ( DTC) is a generic powertrain code, which means that it applies to OBD- II equipped vehicles that have a mass airflow sensor. Quality Promise Wells Vehicle Electronics is committed to providing quality products that meet or exceed our customers' expectations. We foster an atmosphere of continuous improvement and mutual respect among employees, suppliers and customers. That requires proper troubleshooting and a good course of diagnostics based on either experience or proper documentation like a GM FSM. The oxygen sensors that have a direct bearing on how the PCM fine tunes the fuel injection ar O2S11 and O2S21. O2S11 stands for Oxygen Sensor Bank 1 Sensor 1. This bad boy is located on the exhaust pipe that connects to the bank that houses cylinders # 1, # 2, # 3, and # 4. A few days ago I heard a rattling on first startup/ idle. neutral but that went away after a few minutes. The sound was coming from the muffler catalytic convertor area which sounded like something loose inside. Check Engine Lite On/ code P0101/ mass. air flow or volume air flow / circuit range performance problem This code comes on about once a week after i clear it. It stored a DTC code for P0101 and a P0171 and because this is a L6 it stored a P0174 ( fuel trim lean Bank 2) the vehicle had a rough idle and stumbled on acceleration, the fix to replace the torn MAF airduct.

    remember to visit my channel i have more videos that might help you and remember to subscribe thank you so much for watching. Every once in a while my truck will pull a CEL and when I pull the code its a P0101 - Mass or Volume Air Flow " A" Circuit Range/ Performance. gm used the same maf. My code reader listed codes P0101 ( Max Air Flow Sensor Performance), P0171 ( Fuel Trim System Lean), P0174 ( also Fuel Trim System Lean), and it also listed P. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor. Diagnosing GM Digital Mass Air Flow Sensors P0101. Hi P0101 is for MAF sensor performance try cleaning with MAF cleaner. The 300, 306 are engine misses the 430 is TWC cat due to miss. Faulty MAF is most likely the problem but would need diagnostic scan tool to verfy. I cleaned the MAF. Cleared the code. Now I am working on P0135, the oxygen sensor( s) the code reader at Autozone said the O2 on abnk one was the cause of the P0135.

    Oscilloscope Waveform Of The GM MAF Sensor If you have access to an oscilloscope, this is what the mass air flow ( MAF) sensor waveform looks like at idle. If the MAF sensor is good then at idle and at any RPM, the waveform will stay perfectly formed. P0101 - Mass Air Flow Sensor Circuit Range/ Performance The mass airflow sensor ( MAF) measures the amount of air entering the engine. The OBD- II code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn' t work properly. A MAF sensor diagnostic trouble code ( DTC) stored in your vehicle computer' s memory. P0100: Mass Air Flow ( MAF) Sensor Circuit Malfunction. P0101: Mass Air Flow ( MAF) Sensor Circuit Range/ Performance Problem. GM Trouble Codes - Check Engine Light Codes. Welcome to the GM Trouble Codes and Check Engine Light codes page. Below you will find the most complete list of GM trouble codes available. gm forum at Car Dealer Forums; My Buick Park Avenue stalls while driving. I get no SES light but my. p0101 code = mass or volume air flow circuit range/ performance the first thing id be tryin would be cleaning mass air flow sensor especially if you use an oiled filter such as k& n sorry bout caps to lazy to retype lol.

    Trouble Code Fault Location Probable Cause; P0000 – P0099 ( Fuel and air metering and auxiliary emission control). P0101: Mass air flow ( MAF) sensor/ volume air. The code has to be stored in the ecu for freeze drama data to be present. Even if the code is stored but not current, there will be data to review. But as you said, it' s not driveable with the code, so it' s kind of a crap shoot. Code P0171 applies to 4- cylinder engines ( Bank 1) as they generally have only one bank. If you have a V6 or V8 engine you can also get a P0174 code which refers to Bank 2. When the code says that the fuel system is " too lean, " it means that the computer has been adding more and more fuel, which is called Long Term Fuel Trim. If the P0171 is combined with the P0174 code, it' s very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replace the air filter and clean the air flow meter. If the problem persists the front oxygen ( O2) sensor may need to be replaced. This is important information the Engine Control Module ( ECM) uses to calculate the proper amount of fuel for combustion and the amount of ignition timing advance. 02 PM - Post# I have my fingers crossed & I' m knocking on wood etc. but so far so good!

    It looks like the P0101 failure code on our Avalanche which has drove me nuts for quite a few weeks and has baffled at least two " Good" mechanics & a number of novices ( like me) has gone the way of the dodo! So we tried to disable the P0101 DTC on a LMM Duramax but the after effect still is present. For example under the DTC menu we having disabled the P0101 code. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined expected range of the calculated MAF value. My wife was driving her Volt last Friday in 106 deg heat when she got a CEL. The codes showed P0101 and P0102, which both relate to the mass air flow sensor. I checked the air filter, and it looks essentially new. The Code P0100 code is often associated with a P0101, P0102, P0103 and P0104 codes. What the P0100 code means P0100 is the general code for a problem with the Mass Airflow ( MAF) Sensor or Circuitry. Bank 1: Now, to be a little more specific, P0171 DTC tells you that bank 1 is the one having the issue. Bank 1 is the engine bank that holds the spark plugs for cylinders 1, 3, and 5 ( V6 4.

    We recommend Torque Pro. An engine needs three things to run – air, fuel, and spark. To deliver the most efficient power, a precise amount of fuel needs to be injected into the cylinder, after which it is compressed and ignited, resulting in a power stroke. I just keep getting the P0101 code. I had a o2 sensor code but I replaced it. I cleared the codes but this code as well as a evap code keep coming back. CAI is cold air intake. Many put them on in the false hope it will improve performance. Our trucks have cold air from the factory. I asked about it and K& N because over oiling the filter can cause problems with the MAF.

    When I got the code, it was caused by a loose conection on the air tube. Unmeatered air was getting to the system and causing the problem. check all of the clamps and seals on the rubber bellows. Description or check engine light code P0101 or P0102 mass airflow sensor. Also know as the MAF. Read what sets this code and some common causes and repairs. Learning about the Usual Gm Error Code P0101 and How to Eliminate them When you utilize your personal computer and its various functions, it is inevitable to bump to. P0101 GM Digital Mass Air Flow Sensor Diagnostics and Troubleshooting by Wells Solutions. In this video we explore alternative ways to determine a failed MAF with a trouble code P0101. P0101 code definition Mass Airflow ( MAF) Circuit Operating Range or Performance Problem The P0101 code can often be associated with a P0100, P0102, P0103 and P0104 codes. What the P0101 code means P0101 is the general code. Common problems causing the code P0101 in different cars: In some GM and Chevy cars and trucks, the code P0101 could be caused by a clogged up catalytic converter. A clogged up catalytic converter can be verified by measuring the intake vacuum and the exhaust backpressure.
