How To Clean The Maf Sesnor On A Buick 2002 Lesabre

The mass airflow sensor (ordinarily abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor tin can leave your Buick LeSabre's engine running rough, or even inoperable.

A MAF sensor measures the density of the air entering the intake manifold. Information technology passes this data onto your LeSabre's ECU. The ECU uses this information forth with other sensor data to command the amount of fuel that enters the combustion chamber.

If you do make up one's mind that you need a new mass airflow sensor, they aren't as well expensive. And, most of the fourth dimension they are right by the air box and like shooting fish in a barrel to replace.

Faulty Mass Airflow Sensor Symptoms: Buick LeSabre

When the mass airflow sensor has gone bad, you'll definitely experience information technology. Hither are the almost common symptoms of a bad or failing MAF sensor:

Idle Problems– Your LeSabre may run rich or lean when idling, or it may too idle erratically. A rich status is when there is non enough air relative to the fuel in the air/fuel mixture. The exhaust colour is usually darker when running rich. A lean condition is when at that place is too much air relative to fuel in the air fuel mixture. The exhaust color normally doesn't modify.
Hard to Outset– Without knowing the proper amount of air entering into the intake, it tin can exist really difficult for the engine to start. And when it does, it doesn't normally run very well.
Jerking– As you become downwards the road, you'll feel your LeSabre really wiggle and hesitate as the engine speed changes erratically. It's bad for your motor mounts when this happens. Also, jerking tin be caused past bad spark plugs or coil packs.
Decreased Fuel Mileage– Fuel mileage tin suffer without the proper air/fuel mixture.

LeSabre Bad MAF Sensor Diagnosis

If the MAF sensor has gone bad, information technology'll trigger the bank check engine light and provide an OBDII trouble code. This is great considering it helps you narrow downwardly the problem. The two most common trouble codes in relation to the MAF sensor are:

Buick LeSabre P0101 Diagnosis: MAF Sensor
Buick LeSabre P0102: MAF Sensor Circuit Low

There are other codes related to the mass air flow sensor as well, merely these are the most common ones. Here'south a fantastic video on how to diagnose a bad MAF sensor using a multimeter from Ratchets and Wrenches on YouTube.

Cleaning the Mass Airflow Sensor

Often, the mass airflow sensor actually only needs cleaning when they become bad. Some folks recommend using booze because it's unremarkably on hand, and tin can clean the sensor. This is a bad idea, it can ruin the sensor. Uses mass airflow sensor cleaner. It'due south actually cheap and available at any parts store. It certain beats the heck out of having to purchase a new sensor.

Locate the MAF Sensor– It'll be in between the air filter and the throttle body.
Remove the Sensor- Take intendance not to damage the wiring harness or the connector pins that receive the harness in the MAF. Simple manus tools volition be all that you need to complete the chore.
Clean the Sensor– Now that y'all've removed your LeSabre's MAF sensor, it's time to clean information technology. You'll need the MAF cleaner. You are not scrubbing anything. Allow the chemicals do their job. Most a dozen small bursts will exist all that y'all need.

Conclusion

Replacing a bad MAF sensor can make your LeSabre feel like a new vehicle. Good luck with the diagnosis. If in that location is anything that yous would like to add, please feel gratis to exit a comment below.
