My "check engine" light came on a couple weeks ago so I have been trying to diagnose the problem.

I consulted my mechanic and he mentioned that I need two new O2 sensors. The problem is I have 4 O2 sensors on my 1998 Disco. After I replaced the two that I thought were having the issue the "check engine" light has still not gone off.

I went down to Autozone and I had them run a free diagnositic. They came up with 2 error codes 1193 and P0158.

1193 - EGR Drive Overcurrent
P0158 - Bank 2 Sensor 2 Hogh Voltage.

Questions:

First off, I was wondering which O2 sensor is Bank 2 Sensor 2? Is it the passanger side farthest back?

Secondly what is the 1193 error mean?

Lastly, I thought I changed out the correct O2 sensors. Is there something I need to do to reset the "check engine" light?


Thank you for any help you may provide...

Did you double check the sensor connection?

Bank 2 sensor 2 is the sensor behind the cat on the P/S...is that the one you changed? High voltage could indicate a short in the plug. As for the 1193 if its obd2 then its gonna be P1193
Oxygen Sensor Heater Circuit Open Downstream Sounds like you need to check your connections.

So it is probably the Bank2 Sensor2 that is not plugged in correctly or is bad?

Checked connection and it seems tight. IS there something I need to do to reset the "check Engine" light?
