    Pedal Position Sensor

    Okay, I am stumped on this one. I am getting check engine code 1221, which is pedal position sensor fault. I can not find any information on this sensor. Is it called something else. I am getting a rough idle and it appears to be running rich. Anyone have any ideas?

    O2 Sensor Fault

    Could be the O2 Sensor or bad spark plugs

    I have new spark plugs. No O2 sensor codes either.

    Thanks for posting!

    I had looked on this sight http://www.engine-light-help.com/bmw-check-engine-light-code-list.html and they show it as pedal postion sensor. Makes sense though as the light comes on when engine gets to operating temperature. Thanks for posting!
