Over the last two weeks I have gotten p1173 code trigger my CEL light 2x.
I have done some research on the forum and there is not a clear consensus of the fix.
First off I replaced all 4 of my 02 Sensors at 73,000 now I'm right at 100,000 miles. Has anyone found a fix for this code? Rover is running fine. Idle is strong MPG is good at about 14 hwy and city combined.
I was wondering if a super slow oil leak from the drivers side rocker cover could short out that O2 over time. I have have heard that hypothesis before.
Also my right rear O2 gets slathered with grease from my front prop shaft greasing .
I know 02's are finicky in our trucks but was hopping I could get more than 25,000 mine out of mine
Here is some copy from my research:
"1173 is another 02 fault"
"P1173 Land Rover Lambda sensor aging tv bank 2Drive cycle C:Signal out of range -"
"1173, Down stream fuel trim malfunction, Bank 2, Front sensor aged- rear HO2s adaption too lean/too rich Bank 2 NAS and EU-3 only
Talk to your mechanic with the version of an 1173 code."
I would rather not throw parts at this but if it means another $75 O2. I'll go for it.
