I have a 2010 with the 3.0. I recently replaced the timing chains and tensioners after it jumped time. After replacing the chains and tensioners, I am getting codes for bank 1 sensor 2 low voltage and stuck lean as well as codes for the heater side of the sensor. I replaced the sensor and repaired the exhaust leaks I had. I am still getting the same codes. I have checked voltage coming to the sensor and I get 1.5 volts. I also checked ohms on the sensor side and have resistance. Can anyone point me in another direction to look?
