I have a '99 Millenia S and got the code of P0105. Anything I can do?

Thanks.

DTC P0105; manifold absolute pressure sensor circuit malfunction. Located behind passenger side front strut tower, has three wire
connector & vacuum hose. First, disconnect the vac hose, let engine ilde & check for vacuum at the hose end. If not vacuum, trace the hose back to the intake manifold, disconnect & check for vacuum @ the port, clean with drill bit by hand if plugged. If you have good vacuum @ the sensor, then you'll need a hand vacuum pump & voltmeter to check sensor operation. After that the next step is to test for continuity from the sensor connector to the PCM ( powertrain control module)
