You can ignore the P1000 code, that's just information.
It is set each time the fault codes are cleared or the battery is disconnected.
It will disappear when all tests are complete (without any fault).

Both heaters from the Oxygen sensors do not work properly. It is possible that you have 2 defective Oxygen sensors, but I would first check if power is supplied to the heaters.
Maybe there's a fuse blown.
