I did a search and didn't come up with anything. The Service Engine Light came on and I got both these codes. They are P0161 O2 Heater, Bank 2 Sensor 2, P0141 O2 Heater Bank 1, Sensor 2.
The truck has 61K and I finished the 60K service myself a month or two ago. I think it's odd both would fail at the same time. The Rave CD said for both codes short/open circuit. Should I try checking the O2 connections or is there anything else I should check? Are new O2 sensors in order?
I did lightly spray the engine bay to get rid of salt, the night before I got the codes. Could that have contributed?
Also where do the O2 sensors connect to the harness? Again, I think it's weird both sides threw the code at the same time and they are both in the rear. Do the O2 sensor heaters have a fuse or relay?
Thanks in advance!
