Feb 22, 2021· The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
The MAF Sensor has low voltage output problems which may have several causes. The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. The most obvious problem is restricted airflow from the air cleaner to the MAF sensor which can be a clogged air filter.
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean. You’ll notice if the tailpipes eject black smoke or when the engine runs rough or backfires.
The Buick 3800 V6 is a fairly reliable engine, but coolant leaks on the Series II 3800 engines with the plastic intake manifold have been a problem. The OEM intake manifold gasket tends to deteriorate after 60,000 or so miles in the area that seals the cylinder head coolant passage to the manifold. The fix is to replace the intake manifold gaskets.

Aug 06, 2019· 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 GMC Sierra’s engine running rough, or even inoperable.. A MAF sensor measures the density of the air entering the intake manifold.
Jun 18, 2008· The digital 5volt signal is then converted by the PCM into the air flow rate. Normal MAF Readings at idle • Use a scan tool to look at the grams per second • Should read 3 to 7 grams per second • GM 3800 V6 should read to KHz. • If not within this range, check for false air or contamination of the sensor wire
Aug 11, 2016· Re: I have a Buick lasabre 3800 and on my mass airflow... Yes, a dirty or bad mass airflow sensor can cause a car to run badly. I had a 1999 Mazda Protege that had this problem. You can get a can of mass airflow sensor cleaner from an auto parts store. Be careful to hold the can a few inches away from the wires so as not to break anything.
Oct 18, 2009· This article will show you how to test and diagnose a bad GM mass air flow (MAF) sensor on all of the early 90 thru'' mid 90''s Buick, Olds, Pontiac , and V6 equipped cars (to be more specific: 8996). If you need to just clean the MAF sensor, you can find this article here: Cleaning The MAF Sensor (at: ).
