Codes 1170 and 1173
 

Hey Everybody. I am getting these 2 codes but don't know which side of the LR it is talking about.

P1173 Land Rover Lambda sensor aging tv bank 2Drive cycle C:Signal out of range - .............................P1170 Land Rover Lambda sensor aging tv bank 1Drive cycle C:Signal out of range - above maximum / below minimum

I appreciate the help.

Thanks

One sheet I found said for the "LH" bank.
How many miles on your engine, have you ever changed your 02's?

Thanks for the help.

Is that the left side when sitting in the vehicle or standing in front and looking at it? I haven't replaced any of them and know it is time. 90,000 miles.

Is the one code for the upstream and the other for the downstream on the left hand side? That is my guess

right hand and left hand is alway from sitting in the vehicle

At your mileage, I would replace both front 02's and clear the codes, see what happens.
