P12A2 is for the fuel rail pressure sensor. The fuel rail pressure sensor will run around $250 parts and labor to replace. The P2187, system too lean at idle, may very well be caused by the faulty fuel rail pressure sensor as it will cause air to fuel ratio to be off. So the fuel rail pressure sensor has to be replaced first and codes erased.
