· I have changed my mass air flow sensor twice with OEM parts, reset the code multiple times, put a new KN air filter in and the light still comes with in 3 or so miles. I have a 2017 Titan XD with the Cummins. I did find a skinned wire that looks like a rodent got it but I soldered it back together so it is solid. Please start your own thread.

· Hi all, Recently, the Check Engine light turned on and, after taking it to the shop, they tell me that a sensor need to be replaced. It is the Mass Air Flow Sensor. Can anyone tell me 1) Is this is an expensive sensor and 2) Is it difficult to …

Answer (1 of 6): Because either the sensor is reporting incorrect air amount and or air temperature to the ECU. So you either have a bad sensor or the heated sensing wires are contaminated. The MAF sensor measures air weight in grams per second and air temperature and if either of those two are...

· The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Toyota Corolla’s engine running rough, or even inoperable.. A MAF sensor measures the density of the air entering the intake manifold.

· It''s always a good idea to test a Mass Airflow (MAF) sensor before replacing it. With the engine at idle, the MAF''s PID value should read anywhere from 2 to 7 grams/second (g/s) at idle and rise to between 15 to 25 g/s at 2500 rpm, depending on engine size.

· When should I replace the Mass Air Flow Sensor of my vehicle? There is no fixed duration to replace a Mass Air Flow Sensor. They function properly for a long time in case of good engine performance, low emissions, and decent gas mileage. You can use them indefinitely till they function correctly.

· MASS AIR FLOW SENSOR FAILURE. ... Piston ring change is the only solution and this should be done asap. There are also individual cons found in each yearmodel and they are listed below; 2020 Toyota Corolla Sluggish base engine ...

Check My Flow. A MAF sensor is usually placed inline immediately after the air filter, and takes a reading of how much air is entering the engine. It takes account of the air flow and converts it to an electrical signal sent to the ECU. The ECU …

I recently had the mass airflow sensor replace by a local garage on my 2002 Pontiac Grand Prix. I was looking at replacement parts online, and they seemed to be significantly cheaper than what they charged me for the part. When I asked them about the price difference they told me that they used the manufacturer’s part (I think the term they used was “OMC”) instead of using an …

· A MAF sensor code. Lean and/or rich code (s). Fuel trim code (s). A tremendous lack of power upon acceleration. Black smoke coming from the tailpipe. Vehicle may idle rough and stall. As stated before, the Mass Air Flow Test is a very easy and simple test but there are a couple of things that have to be done first.

Sensors: When to Replace Them. See more from Counterman. Sensors provide the inputs the Powertrain Control Module (PCM) needs to make critical control decisions. They are like the nerve endings of the vehicle. Without accurate input data, the computer may not make the correct command decisions. This, in turn, can cause emissions, performance ...

· How to Diagnose a Bad or Failing Mass Airflow Sensor?Mass Airflow Sensors (MAF) have the responsibility of reporting the amount of air entering the engine to...

· If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This is because the computer in the car if it does not receive a reading from the mass airflow sensor, will estimate and supply a number that it thinks it is supposed to have. This means that if your mass airflow sensor dies ...

· The mass air flow sensor is a fairly small part but not the cheapest to replace. The good news is that it’s usually located near the top of the engine and DIY replacement is easy in most cases. Since it doesn’t take that much time for …

· With the Toyota Corolla, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. We will cover exactly what that means and potential fixes for it below. 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.

· Once i replace the mass air flow sensor then I will know if that fixes it or not. but after changing both o2 sensors and not hearing or seeing any exhaust leaks or any other leaks that should fix the check engine light and the code PO133 problem. Any other suggestions please feel free to drop me a message here.
