@lancelott, generally our key indicator of the problem is in the sensor array codes given. Unfortunately, yours is garbled; I'm guessing you scanned a screenshot or picture, but the code we need is unusable. Can you post the original or do a straight copy & paste of this sensor array 0 line?

S.sensor array 0 - 5is 161, 0, O, O, O

Once we have that we can better confirm @oldturkey03's diagnosis.
