check engine light came on for the downstream sensor on my OBDII reader and when i went to the live data on my obdii reader the upstream sensor it gave the approx. 0.4 volts and 2.3% while the downstream sensor gave me 1.000 Volts and N/A %.. do this mean that the sensor if burnt out?? i checked the wiring it is all fine and the fuses are fine i unplugged the sensor and no change. did any body come across this before??
