4/11/2018· Mass Air Flow Sensors are usually easy to locate and if they have done a lot of miles they could well benefit from being cleaned. Very simple, no moving parts and very reliable. You can read more information about Mass Air Flow sensors at Wikipedia here. Mass Air Flow Sensor Symptoms – Problems and Faults.
How to test your mass air flow sensor (MAF) and to quickly know if it is defective. Mass air flow sensor testing with a multimeter without dismantling. Meth...
17/11/2015· This sensor lets the computer know the correct oil pressure is present. Since the efficient flow of engine oil is required to maintain proper lubrication, a failed sensor or one that is not able to relay data can trigger a fail safe mode in the ECU. If it sends a signal that the pressure is low, the computer may prevent the engine from starting.
11/10/2018· Reinstall the mass air flow sensor and clear the check engine light using FIXD. If the check engine light comes back on with code P0171 continue the diagnostic process. If check engine light code P0171 persists after you have reconnected and replaced all damaged vacuum lines and cleaned the mass air flow sensor, perform a fuel pressure test.
17/10/2016· Mass Airflow Sensor Replacement. Get a Quote. Jay Safford. Automotive Mechanic. 16 years of experience. This is a sure sign of a shorted mass airflow sensor. The reason it starts with it off is the computer sees no mass air signal and replaces it with an internal memory fake signal to use. This will let it start and will run ...

ECM operates in backup mode if sensors fail, to enable vehicle to be driven to workshop. Sentra >1999/all other models >2000: Trouble codes can be displayed by the malfunction indicator lamp (MIL) or by using a Scan Tool connected to the data link connector (DLC) 1 [1] or 1 [2] .
The mass air flow (MAF) sensor in a Nissan truck sends a signal to the truck''s computer. As the intake air increases, the voltage from the MAF sensor increases. The truck''s computer uses this signal to determine engine load and adjusts ignition timing and fuel timing for optimum engine performance. If the MAF ...
8/8/2008· Where is the idle air control valve located on a 1995 Nissan Altima and how do you change it? Is it difficult to get to and would I need to jack my car up? My car idles rough and hesistates on accelcelartion I replaced the fuel filter and the mechanic said I should replace my idle air control valve (IACV). can anyone point in the right direction or any help would do.

Mass air flow sensor problems are often caused by deposits left inside the air intake duct. If the mass airflow sensor is sensing hot/cold spots on the air ducts, this is a sign that there may be movement of metal particles within the exhaust stream and a subsequent need to remove them via a chemical wash.
Symptoms of a bad mass air flow sensor include decreased fuel economy, starting trouble, stalling shortly after starting, rough idling, and jerking during acceleration. If your check engine light is on and your car has any of these symptoms, you can check the MAF sensor with an OBDII …
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...
22/10/2018· 03/31/2021 10/22/2018. The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should. The job of the mass air flow sensor ...
MAF Sensor A contaminated or failing Mass Air Flow (MAF) sensor may interfere with your car computer and affect fuel supply to the engine. Check inside the sensor housing first for dirt and debris that may be interfering with the sensing element readings. Consult your repair manual to troubleshoot the sensor for potential problems.
20/7/2009· 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.
