OBDI Code P1170

Hello Guys,

I read that the OBDI code 1170 means that the two O2 Sensors before the Cat Coverter needs to be changed.  I did that and the Check Engine Light still comes on.  Any Suggestions???

By the Way, I have a 2003 Range Rover HSE 4.4

How many miles on your truck??
The fault codes won't go away by them selves, you need to go by your local auto parts store, have them read and cleared, usuallyy they will do this for free.

Mike,

The mileage is 56k.  I was told that I needed to change the O2 Sensors before the Cat- converter.  I did that and reset the codes, but then later that day the codes came back.
