I checked and they are O2 sensors codes. Are they up stream? Before cats.? Also what do they mean when together? This was after a long steep hill.
Thanks,
Dave

I hate to say this but if it is running normally I would probably let it be for a couple days. Than clear the codes and see if they come back. With everything the truck has gone through including sea level change it might just be a glitch

Thanks Army! was thinking same thing. I will clear the codes in the morning and drive and see if they come back. It has been driving fine.

if it pops back up I would check the connections. Make sure they are full seated and free of corrosion. I want to say that code is for upstream sensors.

Hi Army.
So just returned back from PR, had the Drag link and Track rod replaced due to worn out bushings. Did not get a chance to do the water pump yet.
But these two codes P0153 & P0134 retuned from last November when I had it shipped there. I cleared them then, and they did not come back. I drove it a couple of times as I fly there every 2 months or so. Now 8 months later they are back. I got them back the same day I arrived (2 1/2 months of it being parked this time). I cleared them and 80 miles or so they came back. The truck is driving fine though.
Are these 2 codes just for the driver side 02 front sensor, or for both Drivers and Passenger side front sensors? I did see some oil on the front passenger side one, could that be it? Wondering? Should I purchase 2 new front sensors and take them back with me in November when I return? Or clean the bit of oil I saw on the passenger front one?

I also purchased a battery tender to keep the battery from dying since this time I won't return back till mid November.
The battery seems to have hold 2 1/2 months parked, but did not want to take a risk to leave it 3 1/2 months.
Thanks,
Dave

Oil in the connection could cause a problem.

Off the top of my head I don’t remember if it was one side or both

I will get some electrical cleaner and spray the connections and then re install the 02 plug and see, but I will still take the sensors just in case. I have to get the truck emissions inspected there in Nov, it past it last year when I had it registered there.
The LR3's never give us any issues.
