When your mass air flow sensor isn’t working right, your engine will run roughly, idle poorly and could get horrible gas mileage. For most of the modern engines on the road, the mass air flow sensor is the most important electronic input for the onboard computer to make decisions on air-fuel ration. With the Chevy Monte Carlo, P0101 means the the Mass Air Flow (MAF) sensor has a Range/Performance problem. 5L L5 Exhaust & Emission Mass Air Flow Sensor. 2004 Tahoe Mass Air Flow Sensor - MAF Swap I know this is pretty simple stuff for those who are mechanically inclined, but I decided to make this a tech write up in case it helps someone out that could use it. If your vehicle is giving you a MAF code, replace it immediately to ensure you get the best gas mileage and performance. Use the plastic wand that comes with the throttle body cleaner so that you can direct the cleaner onto the throttle body plate (rotate open with your hand) and the throttle body interior. We will cover exactly what that means and potential fixes for it below. Contamination of a MAF’s ­resistors is, by far, the leading cause of MAF calibration errors. Please Log in or Create an account to join the conversation. The Mass Air Flow sensor is a very delicate sensor. The PCM calculates this by multiplying air density by air volume. MAF Sensors) are precision components that measure the amount of airflow entering the intake manifold and must communicate clearly with the Engine Control Module (ECM). Exhaust leaks also damage the Oxygen Sensor, leading to an intake of air which can cause a dangerous increase in temperature. by Jecr. 1L with a MAF sensor) is not hard at all. Forums. Chevrolet-GMC Diesel Diagnostics Inspect the mass air flow (MAF) sensor for obstruction, contamination, and damage. it is connected right on the out side of it. Then, loosen the hose clamp that connects the intake hose and the mass air flow sensor. clean it up real good. The mass air flow sensor senses the total amount of air passing the sensor and allows the fuel injection system to adjust the fuel mixture to compensate for cold weather and/or high altitude conditions. The computer uses this information in conjunction with input from other sensors, to calculate the correct amount of fuel to deliver to the engine. How to clean a Mass Air Flow sensor (MAF Sensor) Discussion in ' GMC Truck Forum - GmFullsize. CRC SensorKleen Mass Air Flow Sensor Cleaner dissolves dirt, grease and flux Will not harm sensitive electronics or plastics Improves the air to fuel ratio of your vehicle The heat generated by the hot film is reduced as the intake air flows around it.

Re: How To: Clean Your Mass Air Flow Sensor ive talked to a guy at work about this cause i get a bit of rough idle myself where i feel it in my seat, but he says there is an after burner if u will that is supposed to burn off and clean itself do ares have that cause im gonna get at this this week and see The Mass Air Flow (MAF) sensor measures the amount of passing air going through the air intake system. A MAF sensor measures the amount of air coming in to your engine. Save time, money, and labor by replacing only the MAF sensor instead of the entire mass air flow assembly. The Mass Air Flow Sensor (also known as Air Flow Meter Sensors) is used to determine the mass of air entering an electronically fuel-injected engine. You will know your MAF (mass air flow) is dirty from either noticing a decrease in gas mileage, power, or just an overall "less smooth" ride in your car. Intake Air Sensor (IAT) Depending on the type of MAF sensor, the IAT can be either located in the air intake tract or internal to the MAF sensor. Our Envoy mass flow sensor improves horsepower and torque because it allows for better combustion. A phillips or flat head screwdriver (depending on the type of clamp used on the throttle body intake hose). thanks Delphi’s Mass Air Flow is engineered for affordability, and convenience. Remove Hose from Throttle Body. Note: Since the MAF sensor calculates the air density, the engine does not need the MAP or baro sensor readings. com , Cabin air filter replacement- Ford Taurus , Cabin air filter replacement- 2011 Ford Explorer , 2001 Ford Expedition Mass Air Flow Sensor - CRC cleaner - try this first. CDN$ 116. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. Replacement restores the engine to proper operation by determining the most efficient air/fuel mixture for achieving clean burns. I found some at my local O'Reillys auto parts store for about 7 bucks a can. You'll surely enjoy big savings and fast delivery! [full online] mass air flow sensor gmc user manual introducing the panamera porsche is proudly presenting the first four door gran turismo in the history of the company a brand new development from the ground up the porsche panamera sets a new A dirty throttle body reduces an engine's ability to breathe just as a dirty air cleaner would. 20147. If the check engine light comes back on with code P0171 continue the diagnostic process. com The Mass Air Flow sensor is crucial to the fuel systems operation. If you understand that a defective mass air flow (MAF) sensor can cause an extremely lean condition by underestimating the amount of air flowing into the engine, then you can understand how a defective MAF sensor can be mistaken for a defective fuel pump assembly. The mass air flow sensor still comes back. Reset code and drive vehicle. Most modern EFI engines have a Mass Air Flow (MAF) sensor located in the air intake of the engine. – Small air leak in the exhaust system between the engine and the Oxygen (O2) sensors. These devices are designed so similarly that a device that works for a MAP also works for a MAF. Two other sensors have been replaced - problem still exists. 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. Use the appropriately designed mass airflow sensor cleaner, or carefully remove the electronics from the housing and clean them separately.
