My truck is showing these codes and Bluff City Rover will not let me speak to a tech. I am sure these are 02 related codes but I am not sure if 1170 and 1173 are also 02 related. I am also sure that 0137 and 0157 are upstream codes coming from right below the headers but should I change all of the 02's? I am under the impression that there are 2 more downstream from the cat. I was also quoted $163.92 for one 02!!!

 

Tell the dealer to F--k off and let us help you.
First, how many miles on your truck?
137 is a low voltage on bank one sensor 2
157 is a low voltage on bank bank 2 sensor 2
Can't find the other 2 but if you are near 100,000 miles I would say replace all for, Atlantic British has them on sale for $59 a piece.
Make sure the dealer writes down the information on the all 4 sensors or tell him you will not pqay for only partial information.

Thanks Mike, I did tell him that in so many words. The other 2 codes look have something to do with both banks running lean, does this sound right? The truck is a 2000 with 90k.

 

Wish I had the defination of those 2 codes.
I would still lean towards 4 new ones.

Mike,

Could the codes indicate a problem with the exaust not being grounded properly?

I went ahead and ordered the o2's. So from what I gathered from redhott I need to check the PVC hoses? This could be causing the 1173 and 1170? Also, will I need to have the codes cleared after the install of the o2's, or will the service light turn off itself? Again I know that these are elementary questions, I am new to the Rover world but the folks on this site have been EXTREMELY helpful!!!!

 

YUP!
All codes need to be cleared once the repair has been made.
