hi, new to the forum. i just picked up a 2001 S60 T5. the check engine light is on and i had the code read. they told me it was "Boost pressure signal too low and signal too low." fromwhat i can find that is the MAP sensor.anybody have any insight or experience with this that can confirm that it's theMAP sensor?

also, the emission system service required light is on too.

thanks!

 

Could be the Map sensor I have seen them go bad.
To find out more I would have to know the code that they pulled.

 

FYI, it was the MAP sensor.

 

well the flipping light came on again today after being out for 2 weeks. stay tuned for further updates.

 

new code was for the coolant. i reset the light and replaced the coolant with new stuff and all seems to be good.

the original problem was the map sensor.

 

The coolant temp sensor or thermostat might be bad see if the light comes back on for the same code.
