Can you give the exact code(33 or34)? Not sure if you mean the MAP signal was low or that the vac was low....

Essentially, the code sets when the computer is reading the voltage too low. If you have verified the sensor is reading correctly, you will want to check the supply voltage to verify it is what it should be, and you will need to check wiring as well.
