I have a 2001 2.7t..the check engine light came on and now turned offso when i got homei used my obdII computer and it said i have 3 codes which are the following....P0154(02 Sensor Circ.,Bank2-Sensor1 No Activity Detected)...P0134(02 Sensor Circ.,Bank1-Sensor1 No Activity Detected)...P0300(Random/Multiple Cylinder Misfire detected)...so since the light is off i dont know if they are current codes or older ones? But if anybody knows what they all mean that would help so much
