Where is the mass air sensor on my 2000 lasabre buick

SOURCE: how to replace a coolant level sensor, 2000 buick century

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

SOURCE: service engine light is on in my 2004 Buick LaSabre

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

The error that I'm showing for error code P1133 is 
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank).  I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done.  Hope this helps.  Thanks for an honest rating and for using FixYa.

SOURCE: My car was diagnoised with a bad air flow sensor

the mass air flow sensor is located under the top plastic engine cover. to remove this un screw the oil filler tube by hand and remove the top cover. its just to the right of center engine. unplug this sensor. next it has two screws to take this off. It is not standard screws so look at it. remove them and replace sensor. After install go to autozone and have the warning code removed. This is done free. 2000 buick lesabre

SOURCE: Where is the Mass Air Flow Sensor?

It is inline with the air intake .They are typically held in the tubing with hose clamps and a 2 or 3 wire connection. Make sure you check for direction of air flow.
