Having problems with your 1992 Lexus Es 300 ?

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?

Answers :

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.
