Hi I have Toyota tundra 5.7v8 he is not starting....

Our dear customer, regarding the problem that your car is facing, which is that the air sensor does not work, this is due to the following reasons:
Accumulation of dust and dirt within the sensors inside.
- The entry of some hard and solid impurities within its internal parts, which causes damage.
- The end of the default life of the sensor as a result of damage and wear of its internal components over time.
The malfunction in the air sensor will make the car driver feel that the engine in the car is suffering from shredding, and the shredding mark appears when the driver stops the car and keeps the engine running, such as standing at traffic lights, or driving on crowded roads.
