Hi Mike

"P1170 Lambda Senson aging tv bank 1drive cycle c:signal out of range" is the exact code my OBD II code reader gives me. So I suppose 1170 or P1170 is the code you're looking for? Sorry, I'm a LR rookie.

You need to run more than one tank of premium to reset the computer. Make sure that you use good gas like Shell, BP, Mobil, Chevron, not assbrand gas. Saving a dollar at the pump will cost more you in the long run.
There is a specific "drive cycle" that you need to do to reset the computer, Google it, it is something like start cold and drive at 35mph for x miles, then full throttle for "X" and then cruise for "x" miles and so on, it might be in your owners manual.
But run another tank of premium first, if it comes on again then try the drive cycle method to reset the ECU.

 

The gas had nothing to do with this 02 sensor fault.
How many miles on the truck?

 

Hey Mike

There's 90,500 miles on the truck. I've only owned it for less then a week but to my knowledge the previous owner hadn't ever replaced the O2 sensors.

 

Good place to start since 02's start acting up at your mileage.
Might check out Atlantic British, they have a pretty good price, around $69.
Replace all 4 and you will probably be fine.

 

I've ordered the parts from BA. I'll let you know how it goes. Thanks for the advice.
