What happens if the MAP sensor is bad?

Hello,

Faulty manifold absolute pressure sensor (MAP) will impact the air fuel ratio.
Some of the common symptoms are rough idle, poor fuel economy, sluggish acceleration, strong smell or fuel, lack of power, hesitation on acceleration, engine stalling, backfiring through the intake, it can also cause the engine to overheat.

What issues are you experiencing?

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
