  The PCM as detected faults in the systems that it monitors. The first thing to do is retrieve the trouble codes by connecting a scanner to the data link connector under the dash. Just take it back to the dealer if the vehicle still under warranty...

  I have the same problem with my 2005 Scion xB. Took it to the dealer where they checked it out and said the downflow, (after the catalytic converter) O2 sensor needs to be replaced.
