ECU- Atmosphric Pressure?

Hi,

I checked my ECU and it blinks 13 times meaning Atmosphric Pressure.
Not quite sure what they mean by this.
Thanks

are you sure it isnt the Manifold Absolute Pressure code?

IDK but if it was would it keep my car from starting.
Like it coughs and coughs like its a bout rdy to start but cant.
Thanks

the MAP sensor is THE MOST IMPORTANT sensor on the car. If you look at fuel/ignition maps, it all depends on MAP sensor input.
