mic canic

the o2 sensor must have a fresh air source outside the exhaust source for comparison
like mike stated
and the o2's receive that from the the o2 sensor wiring. again you should never solder or
crimp a o2 wire below the connector going to the o2 sensor
a 02 can even detect fresh air coming down the exhaust from higher up and send bad
signals( reports )to the pcm which in turn results in poor fuel management adaptives and
will result in a check engine lite to make a long story short
and i did not even mention 02 heater circuts hence the 4 wires and the sensors now
