P0107 OBD-II Trouble Code

[Gerald52]

My 2002 S40 Volvo (152000 miles) has just recently started showing an error code of P0107 (MAP Sensor Low Voltage). I have replaced the MAP Sensor with a new one, reset the error code and after running the car for 30-45 minutes or after starting it 2 times, the check engine light comes on and when you check the codes it comes up with a P0107 again. Next I replaced the Air Filter and spark plugs (4) and coils for cylinder 3-4, rechecked the MAP Sensor and even removed it and tested off the vehicle and it passed. I am at a lost now--VADIS doesn't give me any further information or direction I should go to rid this P0107 code. Any ideas?
