I have a Buick lasabre 3800 and on my mass airflow sensor one wire is clean and one lookes burnt . Would that cause my car to act up?


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. Mass Airflow Sensors are fragile. Let it dry before putting it back in the car. If your car has the check engine light on, they can check the code for your as well. You could go to Autozone, Advanced Auto Parts, Oreilly's, etc. CRC Mass Air Flow MAF Sensor Cleaner Instructional Video

    Code 157


    Error code 157 on your vehicle indicates a problem with your mass airflow sensor. The mass airflow sensor gives a reading based on the air intake and output within the engine compartment. A properly functioning sensor will contribute to better fuel economy. In some instances, you may be able to clean your mass airflow sensor to clear the error code, but the error will most likely return in a short time. Fortunately, replacing the mass airflow sensor is a reasonably simple repair.

    Is the metal flap on Maf sensor on 92 Lexus es300 supposed to move with gas pedal if car is not running? Will a bad maf cause no apart or a no start condition?


    No. The metal flap in the mass aiflow sensor is not connected to the throttle control. The air moving through the mass airflow sensor moves the flap. The flap works a variable resistor inside the mass airflow sensor. The more (and faster) the air is that moves through the sensor, the farther the flap will move...that is how it measures how much air is entering the engine....that is what a mass airflow sensor does.

    A bad mass airflow sensor can cause all kinds of fuel control problems that can range anywhere from a hesitation on acceleration to a complete engine no-start condition.

    When I get to 60 mph or when I first crank up my 2000 Buick lasbre stalls.


    First check fuel pressure to specification. My suggestion is a faulty mass airflow sensor. At idle lightly tap on mass airflow sensor with screwdriver handle and listen for erratic change in engine rpm. Wiggle airflow sensor connector and listen for any changes also. Replace sensor if rpm changes.

    The mass airflow can get dirty and you will get trouble codes for everything under the hood except for the mass airflow. Try unplugging your mass airflow and driving the vehicle, if your problem goes away you need to clean the sensor. Buy some mass airflow cleaner though because other cleaners can damage the coating on the sensor.

    X TYPE YELLOW WARNING LIGHT


    I recently had the same code come up when my car failed to start in the mornings. It also said that the crank sensor had failed. Having changed the sensor and still not starting it went back to the garage. According to a Jag enineer the ECU will fail to register if it gets less than 12v from the battery, this will also throw up several codes for the diagostics. Solution, change the battery. Problem solved.
