This seem to be a wiring problem. It codes out to be low voltage form No 2 O2 sensor. Once the car is ran local for approx 5 mile lite out no code.Just had the yearly emission and it passed but the day before the lite is lit. Have purchased a new o2 sensor but the wiring is real brittle and a little afraid of the night mare that lies ahead
