MAP sensor vehicle v6 motor 1992


What is the question? A manifold absolute pressure sensor is a measure of intake manifold vacuum. The sensor sends a varying voltage signal to the computer based on the actual pressure, or vacuum, in the intake manifold. The pcm uses the signal to help compute amount of fuel required for the given conditions . If engine is accelerated, it has a load on it-vacuum is momentarily reduced. The pcm senses this load and knows to add more fuel.

MAP sensors been around a long time-ever since the onset of fuel injection during the 1980's. The auto giants had to be dragged kicking and screaming into new technology. I have a '92 Buick with a MAF sensor (mass air flow) and no MAP sensor. But my son owns a 2005 Buick century with both a MAF and a MAP sensor. I guess they are getting more sophisticated, more precise in fuel economy. Heaven knows, we need that, given our guzzling habits, appetites, and indulgences. I have been accused of moralizing too much, so I am responding with vigor!

Dose the buick park avenue use a map sensor or a mass air flow sensor. or are they the same thing


They are different types of sensors, but in your car the MAP (manifold absolute pressure) sensor, along with the BAROmetric sensor are used to estimate the required fuel flow through the throttle body injectors. These sensors measure pressures inside and outside the engine to estimate airflow. You do not have a MAF sensor. These are more common in later vehices with mulit-port fuel injection. A MAF sensor actually measures the airflow into the engine using a hot wire anemometer. You are correct in believing the sensors serve the same purpose, that is to calculate the fuel flow required for stoichiametric combustion. The oxygen sensor also feeds back to the computer to further refine the fuel charge by measuring oxygen in the combustion products. If excess oxygen is detected, the fuel charge is increased. This is known as closed-loop operation. Closed loop operation is not started until the engine is at operating temperature. If you have more questions, please let me know. I have pasted the location of the MAP sensor below. The sensor is mounted to the air cleaner, but it has a vacuum hose that leads to the throttle body, which is where the pressure must be measured.

Where is the pcv valve on a 2002 buick lasabre


The PCV valve is located under the map sensor in a plastic housing. If you stand on the passenger side of the vehicle and look under the hood, the map sensor is the sensor right in front of you.

It should have three wires going to it. If you look closely, the sensor is clipped into a type of cap. If you grab the cap the sensor is clipped into and twist it counterclockwise, it should come off and the pcv valve will be inside. You may need new orings to prevent oil consumption. You may also need a needlenose pliers to remove the sensor from the upper intake manifold.

Hope help.

WHERE IS THE MAP SENSER MANIFOLD ABSALUTE PRESSURE SENSER ON A 92 BUICK PARK AVENUE


You have a mass air flow sensor in between air intake hose and throttle body. ( round cylinder with wire connection.) Don't believe there is a MAP sensor on that model/year. Call to parts store, should verify that.
